3-Pass Fire Tube Boilers

Water Tube Capacity With Fire Tube Efficiency

Each set of tubes that hot combustion flue gas travels through before making a turn within the boiler, is considered a "pass." A 3-pass firetube boiler design consists of three sets of horizontal tubes (Including Furnace), with the stack outlet located on the rear of the boiler. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler.


Generally speaking, a boiler with more passes provides more opportunities for hot gasses to transfer heat to the water in a boiler and operate more efficiently, however, boiler efficiency is highly affected by tube design, and not simply the number of passes. It is possible for a 3-pass boiler with a tube design (such as XID boiler tubes) that allows more heat transfer time to deliver the same or higher efficiency rating than a 4-pass boiler with standard tubes.


3-Pass Fire Tube Boilers Offer:

  • maximized heat transfer
  • minimal refractory
  • high steam/water storage
  • effective handling of wide load demands

Trust the Fire Tube Boiler Experts at S V ENGINEERS


S V ENGINEERS proudly manufactures and sells new 3 pass firetube boilers, and also has the expertise to provide on-site or in-house service and repair for 3 pass boilers from other manufacturers as well.


In addition to an in-stock inventory of used 3 pass boilers, we offer firetube boiler customization to meet any specification. Firetube boilers can be shipped individually, on a packaged skid, or as complete "boiler in a box" solution. And as as a fully licensed General Contractor with divisions dedicated to every aspect of the boiler room inside and out, we are able to provide system design and engineering, concrete work, electrical services, process piping, and more to provide a total steam plant solution.


Our 3-Pass fire tube Boilers are available with capacities ranging from 500 kg/Hr to 6000 Kg/Hr with working pressure ranging from 7 Kg/Cm² to 21.06 Kg/Cm² with firing medium being oil fired burner, agro-waste, fire wood and briquettes in the following different designs :

1] 3-Pass Dry Back

2] 3-Pass Fully Wet Back

3] 3-Pass Semi-Wet Back

4] 3-Pass Reverse Fired Dry Back


Contact S V ENGINEERS today to purchase a new 3-Pass Fire Tube Boiler and to  know about the various models of different capacities.


4-Pass Fire Tube Boilers

Maximized efficiency with lower maintenance cost

Each set of tubes that hot combustion flue gas travels through before making a turn within the boiler, is considered a "pass." A 4-pass boiler design consists of four sets  of horizontal tubes (Including Furnace), with the stack outlet at the front of the vessel. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler. 4-pass boilers leverage natural draft operation which allows cool water to contact the hottest part of the boiler.


Generally speaking, a 4-pass boiler provides more opportunities for hot gases to transfer heat to the water in a boiler and operate more efficiently (yielding a higher overall heat-transfer co-efficient).


4-Pass Fire Tube Boilers Offer:

  • maximized heat transfer
  • minimal refractory
  • high steam/water storage
  • effective handling of wide load demands

Trust the firetube boiler experts at S V ENGINEERS

S V ENGINEERS proudly manufactures and sells new 4-pass firetube boilers. We are also authorized to serivce and repair 4-pass boilers from other manufacturers as well, both on-site and in-house at our facility in Mysore, Karnataka.

Wet-Back Vs Dry-Back Fire Tube Boilers

Understanding the operational design differences

Firetube boilers are available in either dryback or wetback design. They are identified by the type of reversal (turnaround) chamber, or posterior portion of the combustion chamber, through which flue gasses travel through the furnace to second-pass tubes to heat water within the boiler.

Wet-back Firetube Boilers

The wetback boiler design features a reversal chamber that is jacketed, or completely surrounded by water, which is used to direct flue gasses from the furnace to the tube banks. The surrounding water absorbs burner heat, helping improve operating efficiency as heat from combustion goes directly into evenly heating water instead of refractory. The wet back boiler design uses separate tube sheets between tube passes which can be more forgiving with load changes.


Wetback firetube boilers offer a more optimal functional footprint, with lift off or split-hinged doors that require no cool-down period and can be opened immediately. While there is no expensive refractory to maintain, internal pressure vessel maintenance (i.e. cleaning and tube removal) can be more involved and challenging.

Dry-back Firetube Boilers


The dryback boiler reversal chamber has a rear wall that is lined, or jacketed with refractory, which passes combustion gasses from the furnace to multiple tube sheets and reflects burner heat, resulting in exterior radiation losses. The dry back boiler design uses a common rear tube sheet and features convenient fire-side and water-side access.


Dryback boilers have a larger functional footprint due their heavy, vessel-sized rear door which requires sufficient space to open and a cool-down period prior to opening. Dryback boilers also require regular refractory and tube sheet inspection, which can be costly maintenance items.

We can help you make an informed decision based on your unique circumstances and provide the boiler that's just right for you.



Solvent extraction is used to extract Essential Oils from plants that cannot withstand the high heat used in steam distillation. Very delicate aromatics, Jasmine, Linden Blossom, etc can not survive the process of distillation. To capture their magical aromas, a process of solvent extraction is used. For some plants, the intense heat damages them so, that the essential oils are unusable therefore, they must be extracted via other means.

For essential oil solvent extraction methods one might use alcohol, hexane, ethanol, ether, methanol or even petroleum to coax the oils out of the plant. Most people don’t approve of these methods, however, because some of the solvent will end up in the final essential oils that are consumed. This makes for an impure oil, that aromatherapy and healing purists won’t tolerate.

An extracting unit is loaded with perforated trays of blossoms. The blossoms are washed repeatedly with a solvent (usually hexane.) The solvent dissolves all extractable matter from the plant whch includes non-aromatic waxes, pigments and highly volatile aromatic molecules. The solution containing both solvent and dissolvable plant material is filtered and the filterate subjected to low pressure distillation to recover the solvent for further use. The remaining waxy mass is what is called the concrete and it contains in the case of Jasmine grandiflorum as much as 55% of the volatile oil.


The concentrated concretes are processed further to remove the waxy materials which dilute the pure essential oil. To prepare the absolute from the concrete, the waxy concrete is warmed and stirred with alcohol (usually ethanol.). During the heating and stirring process the concrete breaks up into minute globules. Since the aromatic molecules are more soluble in alcohol than is the wax an efficient separation of the two takes place. But along with the aromatic molecules a certain amount of wax also becomes dissolved and this can only be removed by agitating and freezing the solution at very low temperatures (around -30 degrees F) In this way most of the wax precipates out. As a final precaution the purified solution is cold filtered leaving only the wax-free material (the absolute.)


After the solvent extraction process has been completed, the resulting absolute will have an extremely low concentration of solvent residue, approximately 5 to 10ppm (parts per million). The current European Union standards are for less than 10 parts per million solvent residues in a finished absolute.7 However, even with such a potentially small residue (less than .0001%), many aromatherapists disagree with the use of absolutes for individuals with a compromised immune system due to the potential effect of the residual pesticide. Absolutes are highly concentrated aromatic substances and are obtained from delicate flowers by either enfleurage or solvent extraction. Absolutes will most often resemble the natural aroma of the plant and are normally more colored and viscous than essential oils. Absolutes are used extensively in the cosmetic and perfume industries due to their strong aromas. There are also different grades of absolutes. The top grade is the uncut, which can be a thick or semisolid substance, making them difficult to work with. Less expensive grades are diluted with alcohol to make them more user friendly, although often the strength of aroma is slightly diminished.

As the name implies, force is used to drive the liquid through the evaporator tubes thus producing high tube velocities. A high efficiency circulating pump, designed for large volume and sufficient head, is used to supply the force. Proper design results in controlled temperature rise, controlled temperature difference and tube velocities that give optimum heat transfer. Forced Circulation Evaporators are recommended for viscous, scaling and salting liquids. As the liquid is only heated in the steamchest with flashing taking place in the separator and no boiling taking place within the tubes, fouling on hot tube walls is reduced.

SVE's Forced Circulation Evaporators may be equipped with either horizontal or vertical steam chests. The circulating pump withdraws liquid from the lower part of the vapor-liquid separator and circulates it through the tubes at a high velocity.  Boiling is suppressed in the tubes either by liquid head or an orifice plate. The heated liquid is discharged into the separator where the vapor flashes off due to the temperature difference and is removed through the top outlet. The liquid is discharged at a maintained liquid level. 



  • Operates with extremely low temperature differences

  • High tube velocity

  • Velocity mechanically produced and controlled

  • Gives high rate of heat transfer, rapid evaporation and high concentration without requiring high operating temperatures or large heating surface

  • Maximum recovery of solids

  • Can use horizontal or vertical tubes

  • Tubes are readily accessible for cleaning and inspection

  • Suitable for single or multiple effects


Product Application:

  • Very viscous liquids

  • Scaling liquids tending to produce scale


Examples of Forced Circulation Application:

  • Organic Jaggery

  • Acid Raffinates

  • Glycerin

  • Irish Moss Extracts

  • Sodium Sulphate

  • Gelatin

  • Heat-sensitive materials
  • Crystal producing liquids
  • Glue
  • Pectin Solutions
  • Sugar Esters
  • Tomato Paste
  • Yeast Cream
  • Ammonnium Sulphate


  •  In forced circulation evaporator there is a rapid liquid movement due to high heat transfer coefficient.

  • Salting, scaling and fouling are not possible due to forced circulation.

  • Thess evaporators are suitable for themolabile substances because of rapid evaporation.

  • It is suitable for the viscous preparation because pumping mechanism is used.


  • In forced circulation evaporator the hold up of liquids is high. The equipments is expensive because  power is required for circulating the liquids, and hence pumping costs will be very high.

Retubing and Tube Replacement for Boilers of all sizes

S V ENGINEERS specializes in the retubing of firetube boilers, watertube boilers, superheaters, pre-heaters, heat exchangers and other pressure vessels. Boiler tubes must be able to endure extremely high temperatures, pressures, and potentially wide fluctuations in demand depending on the application. Boiler re-tubing and tube replacement can extend the life of the boiler, and saves the tubes from deteriorating due to scale build up and cracking. Boiler retubing can be completed by our experts onsite at your facility, or at our Mysore, Karnataka, fabrication and repair shop or as required. S V ENGINEERS also provides a large variety of emergency rental boilers to keep operations running during repairs.

Boilers and auxiliary equipment should be professionally checked every year. Contact S V ENGINEERS for information on our annual equipment service and maintenance contracts. Regularly scheduled inspection and proper boiler maintenance can improve efficiency, and prevent costly and unexpected interruption in production.


S V ENGINEERS can retube boilers by all leading manufacturers of India and abroad, restoring them to factory specifications. We also offer custom bent tubing, cracked tube sheet repair and tube sheet replacement. We provide custom welding in house or on-site, and offer a complete inventory of replacement boiler tubes in all sizes, thicknesses and materials.

S V ENGINEERS' Boiler Retubing process includes:

  • Inspection - SVE visually inspects each boiler, and perform NDT testing as needed. We use dye penetrant testing to expose areas of boiler tube sheet cracking.
  • Boiler Tube Extraction - old boiler tubes are removed along with the tube ends. Any minor tube sheet cracks are then repaired to the IBR code specifications.
  • Boiler Tube Installation - new boiler tubes (manufactured to meet or exceed specifications) are installed, rolled, beaded and sometimes welded (in the hot pass).
  • Boiler Testing & QC - SVE hydro-tests the boiler, witnessed by Inspector of Factories and Boilers. The boiler is then closed and prepared to fire using all new gaskets. We visually check scale and fits during this phase. SVE can provide ultrasonic thickness testing, or boroscope the inside of watertube boiler tubes as required. We can also handle code repairs to access points, nozzles and other related equipment.
  • Documentation - SVE provides all completed repair forms for submission to Inspector of Factories and Boilers & other applicable regulatory agencies.


Whether performed in house or on site, SVE has all the necessary retubing equipment required to handle boiler tube replacement, including:

  • Tube expanders
  • Tube & pipe cutters
  • Tube lubricants
  • Extension couplings & universal joints
  • Handhole cleaning and seat grinding kits
  • Tube end polishing kits

Extend the Life of your Boiler:

Tubes are the heart of any boiler unit. Improper deaeration and water treatment can significantly affect the lifespan of tubes. Additionally, tube replacement can often indicate water quality issues that need to be addressed.


Retubing can increase the life of the unit by many years. If you are experiencing excessive scale or system leaks, SVE can help you determine whether tube replacement is the best option, or if it’s time to replace/upgrade your boiler.


  • Excessive scaling adheres to the tubes
  • The tubes become pitted (holes caused by oxygenation, overtreatment of water chemicals, stresses or strains, etc.)
  • Tubes continue leaking at the tubesheet after several attempts to roll them


Contact SVE today to discuss your boiler retubing and repair needs, or for more information on our re-tubing services, boiler tube replacement and onsite installation. We have experienced crews ready to assist you.

Tuning Industrial Boilers for optimal efficiency


Boiler tuning is an important maintenance item used to adjust the air to fuel ratio in the boiler and achieve maximum combustion efficiency - the measure of how effectively the heat content of a fuel is transferred into usable heat.


Beyond ensuring long term equipment life and operational reliability, highly efficient boiler systems can mean significant bottom-line cost reduction, NOx reduction and fuel savings. Boiler tuning should be performed each year to maintain peak efficiency.


A regular boiler tune-up provides an opportunity to verify current boiler operating performance and establish a baseline for optimization adjustments, such as fine-tuning the amount of excess air available to completely burn the fuel. Using the optimal amount of excess air minimizes heat loss up the stack and improves combustion efficiency. It is not uncommon for boilers to operate at greater than desired excess air levels, resulting in in heat lost due to the increased flue gas flow, which lowers the overall boiler fuel-to-steam efficiency.


Two primary indicators used to measure combustion efficiency are flue gas oxygen (or carbon dioxide) composition and stack temperatures.

  • Flue gas composition indicates whether the fuel is being burned as efficiently as possible.
  • Flue gas temperature indicates how effectively combustion heat is being transferred to the boiler water.

Protect your Boiler and equipment investment

Just like the car you drive every day, industrial or commercial boilers and auxiliary boiler equipment need to be properly maintained at recommended intervals for peak performance and long service life. Additionally, a certification of inspection is needed to operate from year to year. S V ENGINEERS is your one-stop-shop for boiler inspection, planned outage maintenance, emergency service, and on-site equipment assessments.

Annual Boiler Inspection

Every boiler and pressure vessel in the United States above 15 lb requires an annual inspection, generally led by a licensed inspector from a commercial insurance provider. Annual inspection is typically geared toward a specific piece or set of equipment and involves a planned outage to open the boiler(s) and inspect the fire and water side.

A qualified service company like S V ENGINEERS works side by side with inspectors to record any problems and identify and make repairs that may be required such as tubing, refractory, gaskets, controls, etc.


Specifically, an annual boiler inspection addresses the labor, material, equipment and supervision to:

  • remove all safety relief valves, and replace them with valves provided by customer
  • open the boiler(s), inspect tubes, tube sheets, level controls
  • close the boiler(s), clean outside area and prepare for firing
  • perform calibration service and performance testing on the boiler safety interlocks, controls and valves
  • inspect related equipment including deaerators, feedwater systems, economizers, blowdown systems, etc. as applicable


Boilers and equipment which pass inspection receive a new annual certificate of operation. Keep your steam plant operating at its best – ask about our annual maintenance contracts!

Planned Outage Maintenence

Planned outages are used to conduct annual equipment inspections, install new equipment and make upgrades, and address routine maintenance items and repairs to industrial boilers and auxiliary equipment within a designated window of time. A successful plant or process outage requires a qualified service provider with sufficient manpower availability and experience to expect the unexpected, with a contingency plan in place to meet project deadlines. It also requires proper planning to order new or used equipment, or check the availability of rental equipment as needed with sufficient lead time to secure for any pieces taken out of service.

With planned outage maintenance through S V ENGINEERS, you can expect:

  • service tech crew scheduling
  • project management & client communication
  • equipment rental & purchase management
  • safety oversight
  • inspector coordination
  • service/maintenance reporting
  • system testing & restoration
  • contingency planning

Emergency outage service and repairs

Unplanned outages happen when you least expect them, and somehow it’s always at the worst time. Equipment failure and emergency shutdowns can be extremely stressful and costly as well due to lost production time. SVE’s Field Service & Repair division and Parts divisions are both available 24/7 for emergency help. Additionally, our Rental Boiler division has a wide variety of trailer mounted or skid mounted rental boiler units in stock ready to ship and have you up and running in as little as 24-48 hours. Regardless of the type of emergency service you need, SVE has depth of experience and manpower to handle your toughest challenges and limit down time to bring your operation back online quickly.
