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.

Steam Generators vs. Steam Boilers. a steam boiler is a pressure vessel comprised of a large shell in which the hot gases of combustion pass through one or more boiler tubes connected to the front and rear boiler sheet. The most common firetube type is the scotch marine firetube boiler, which utilizes a large furnace tube and many smaller
File Size: 195KB May 27, 2019· What is Boiler:-A boiler is outlined as “A closed vessel during which water or different liquid is heated, steam or vapor is generated, steam is super heated, or any combination therefrom, besieged or vacuum, to be used external to itself, by the direct application of energy from the combustion of fuels, from electricity or energy ”.A Brief Introduction :
The steam boiler operates on the same basic principle as a closed container of boiling water. By way of comparison, it is as true with the boiler as with the closed container that steam formed during boiling tends to push against the water and sides of the vessel. Because of this downward pressure on the surface of the water, a temperature
The 400, 500 and 600 HP capacity range of firetube boilers covers the mid-range of industrial and large commercial facility steam plants. This size boiler is commonly requested for lumber mills using steam to power dry kilns, hospitals who need building heat & sterilization steam, and meat processing plants among other applications. 400 - 600 HP boilers come in a wide variety of pressures
For judging the fuel efficiency of boilers, most rely on fuel-to-steam efficiency, which is the most popular measurement for boiler efficiency. However, fuel-to-steam efficiency doesn’t always tell the whole story. Another way to judge the efficiency of an industrial boiler system is to calculate its in-service efficiency.
The following tables are extracts of recommended levels from APAVE (Association of electrical and steam unit owners), up to pressures of 100 bar for medium steaming rates and for volumes of water in the chambers sufficient to properly control the blow down rates, and from ABMA (American Boiler Manufacturers Association) in its standard
“Low Endotoxin Steam” are encountered in the pharmaceutical industry, and may have specifications that are the same or different to those of Clean Steam used on other sites. The important point is that each site or facility must have its own written specification for a grade of steam used in its
In a steam boiler system, there are three potentially destructive elements: oxygen, carbon dioxide, and solids. 2.2.2 As the boiler water is heated and changes to steam, free oxygen is released, carbon dioxide is released from the solids, and the solids drop out (precipitate). 2.2.3 As the steam is used in the end process, it cools and condenses
Apr 02, 2020· The steam valve is a small opening at the top of the tank, usually fitted to a pipe. Most high-pressure steam boilers also have a chimney that helps expel excess heat from the system. The operation of a steam boiler is equally simple. The heating element is brought to a high temperature. The tank water eventually will begin boiling and creating
