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.
Hot Water Boilers - The most economical chemical to use is a blend of Sodium Nitrite. We have a more complex boiler system. Will these chemicals work for my boiler system? For more complex steam systems such as high steam pressure or turbine boilers, more advanced boiler chemicals are used.
Solid Fuel Fired Boilers Coalmiser HPD CG This system is designed by HBC to combine the best technologies from the “old school" of coal combustion and the …
Apr 14, 2017· Energywise you should be making a profit (for a quick test I threw 100 solid fuel in a boiler and got out 520 soild fuel from one depleted well, refinery and chemical factories). Obviously it is possible to come up with scenarios where you would lose energy (e.g. if you build a billion refineries for one oil well then the idle draw may eat most
Some industrial and utility boilers may use No. 6 oil as the alternate fuel. No. 6 is a heavy residual oil that must be heated to approximately 150 o F to be easily pumped. If No. 6 oil were fed to a boiler that was set up to burn No. 2, the burner would not burn the fuel …
The fuel a solid fuel boiler runs on is referred to as “solid fuel”, solid fuel can take many forms, such as coal, wood, paper – the safe fuel you would normally feed a fire with at home, although it is highly advised against feeding a solid fuel boiler with processed types of …
A variety of fuels are available for use in boilers, each having different chemical properties. Each different fuel requires its own apparatus to handle, store, and deliver the fuel to the boiler. When designing a boiler, consideration is given to cost of a fuel, availability of a fuel, efficiency of a fuel, and burning characteristics of a fuel.
All steam boilers have four independent systems. The feed water system supplies water to the boiler, the fuel system transports the fuel, the draft system controls air flow for fuel combustion, and the steam system collects and controls the produced steam. The most commonly used fuels are coal, natural gas, and oil. Usage Examples
Further, about 50 percent of all large industrial boilers (>250,000 MMBtu/hr) use solid fuel, which include different combinations of biomass, coal and other waste products.
Solid Fuel boilers The high specification central heating boiler offers a range of sizes to suit every home. Smaller freestanding independent boilers are designed to provide domestic hot water and enough central heating for a small house or cottage, while larger models will provide domestic hot water and central heating for large properties.
Effect of chemical additives on hard deposit formation and ash composition in a commercial circulating fluidized bed boiler firing Korean solid recycled fuel. Fuel 2019 , 236 , 792-802. DOI: 10.1016/j.fuel.2018.09.020.
What steam boiler chemical program should I use? For high steam usage boilers or very low returned condensate boiler systems, generally a 3 or 4 drums chemical program is used. For lower steam usage boiler systems, a 1 to 2 drum boiler chemical program may be used to reduce the number of chemical …
