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.

Based on the size of the boiler or steamer the rating of the fan used differs and based on the type of air flow and the process involved different types of draught fans are used in thermal power plants. An attempt is being made to explain the types of draught fans used in thermal power plants in an easy to understand format in this article.
The Industry's Best Residential Boilers As a heating professional, you know the boiler is the most important piece of equipment in any residential heating system. In addition to keeping your client’s home at the ideal temperature, the right boiler will provide it with reliable heating, consistently and affordably for years into the future.
Power: 37-315 kW. Surface Treatment: Powder Coated. Air Volume: 43591-166100 CMH. Blade Material: Steel Plate. Power Source: Electric. Voltage: 380 V/440 V/3 KV/6 KV
A balanced draft system forces air into the furnace where the combustion gases are removed by natural or mechanical means. These systems are regulated so that the forced draft fan supplies a sufficient amount of air necessary for complete combustion of the fuel and the induced fan removes the flue gases keeping the pressure slightly below atmospheric
A boiler is a sealed, usually steel, vessel that contains the combustion of one of several types of fuel including wood, coal, oil, or natural gas. The fuel heats water, which is then sent through pipes to radiators or to a fan coil unit that will heat air.
The actual Weston 4 fan size in terms of horsepower, inches of static pressure, total volumetric flow was decided by Babcock & Wilcox (B&W), under the boiler contract.
