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.
Circulating Fluidized Bed (CFB) – In a CFB boiler, the crushed coal, normally mixed with crushed limestone, is fluidized by passing pre-heated combustion air upward through a distributor plate.
Jan 18, 2015· CFB boiler uses coal powder with size nearly ranging from 3mm to 8mm. 2. In PC boiler,Combustion of coal takes place at a high temperature nearly ranging from 1200–1500deg Celsius. CFB boiler has moderate furnace temperature.
Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler.
The circulating fluidized bed boiler (CFB boiler) is the second-generation fluidized bed boiler, the updated version of the bubbling fluidized bed boiler (BFB boiler).

Ultra-Supercritical Circulating Fluidized Bed (CFB) Boilers. 660 MWe for lignite B, higher for hard coal, for low-grade and difficult-to-burn fuels such as anthracite, lignite, petroleum coke, oil shale, discarded coal and biomass, GE offer circulating fluidized bed technologies with different arrangements suited to …
Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures. This series explains the working of the boiler in modern power plant.
Circulating fluidized bed(CFB) power plant boiler mainly used for large central heating, thermal power plants to generate electricity or other purposes. CFB Power Plant Boiler Feature 1, power saving: the fans can reduce more than 30% power consumption.
