WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
Nov 01, 2019· The main difference between Fire Tube and Water Tube Boiler is that In Fire Tube Boiler hot flue gases pass through tubes and water surrounds them, and In Water Tube Boiler water passes through tubes and hot flue gasses is surround them. These boilers are largely used in power development and other industries like sugar industries, cotton
May 04, 2017· Water Tube Boiler: * Water circulates in tubes and heated externally by hot gases. Fuel is burned inside the furnace. i.e (hot gases- outside the tubes and water- inside the tubes). * Operating pressure = upto 100 bar * Efficiency = upto 90% * Ste
Difference between fire tube boiler and water tube boiler Water Tube Boiler. Strength of Materials (P-2) - - *Calculate the maximum allowable pressure difference* allowed between the inside and outside of a sphere 50 mm mean diameter with a wall 0.6 mm Mechanical Engineering
The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam. Here are a few key differences between the two:
Author: Raihan Kabir The water tube boiler can also handle higher pressure in applications that require more than 350 psi, unlike the fire tube boiler, which has greater pressure limitations. The physical size of a water tube boiler unit can often be a deciding factor when choosing between a water tube or fire tube boiler, because these types of commercial boilers
Difference between Fire Tube Boiler and Water Tube Boiler. The comparison between two boilers namely water tube as well as fire tube mainly includes working pressure, material type, the rate of steam production, the requirement of floor area, efficiency, load handling variation, design, operator skills, the cost for maintenance are discussed below.
Apr 23, 2016· The difference between fire tube boiler and water tube boiler can be done on various points. These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler is very crucial.
Jun 13, 2013· Let’s not forget that there is a tremendous difference in water volume between a firetube boiler and a watertube boiler. From a cold start, the firetube boiler, due to its larger water volume, takes longer to bring up to operating temperature or pressure vs. a similar sized watertube boiler.
The difference between the two is that the Water tube boilers are safer and last much longer than the fire tube boiler. Their size is also larger and have a faster recovery time.

A fire tube boiler transfers heat through tubes via thermal conduction, which then heats the water in the container and formulates steam. In other words, the boiler is the pressure vessel that contains the water. Difference between fire tube boiler and water tube boiler. a. Water tube boiler have higher rate of steam production compare to fire
