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.

Cited by: 85 Our Circulating fluidized bed combustion for biomass boiler manufactured strictly according to national and international standard. our products have approved ASME, IBR, ISO9001-2008, etc All our company's products are 100% factory inspected to ensure the high quality.
David A. Tillman, in Coal-Fired Electricity and Emissions Control, 2018. 2.1.3 Control of NO x. Fluidized bed boilers of all types are, by virtue of their combustion temperatures, low NO x generators. Operating the reactors at temperatures ≤1700°F virtually eliminates formation of any thermal NO x.All NO x is generated from the conversion of fuel nitrogen.
Drawing upon our extensive technical expertise and operating experience, B&W developed the Internal Recirculation Circulating Fluidized-Bed (IR-CFB) boiler which is the technology of choice for power plant owners seeking economy, reliability and flexibility. In addition, load-following capabilities are attainable with B&W’s in-bed heat exchanger technology.
Advantages of CFB steam boiler. CFB boiler usually has high thermal efficiency ranging from 97.5% to 99.5%. With CFB, solid fuels (coal, biomass) are circulated all the way to the top of the combustor, into the cyclone return system, then back to the fluidized bed combustion chamber.
The present investigation is unique because it focuses on the correlation of actual fouling, heat transfer rate, temperatures, corrosion and fuel composition over a 7 year period in a biomass fired circulated fluidized bed boiler (CFB-boiler), Boiler 5 at Mälarenergi, Västerås, Sweden.
The Delano plant (Figure 2) has two generating units, each with a bubbling bed boiler manufactured by Energy Products of Idaho and an Alstom steam turbine. Unit 1 is 32 MW and Unit 2 is 26.5 MW.
Biomass has higher moisture which reduces boiler efficiency, again requiring more pounds of biomass to be fired. Biomass bulk density can be as little as 1/10 that of coal per unit heating value
Author: Sumitomo SHI FW Biomass Fired Fluidized Bed Combustion Boiler Details 2017-12-13 16:36:13. Biomass combustion technologies burn a variety of biomass fuels, including wood, crop remnants, wood pulp and chips, and municipal solid waste.
Biomass circulating fluidized bed boiler design A biomass fired CFB boiler is a kind of boiler taking advantage of CFBC combustion technology, which can burn all kinds of biomass fuels, for example, our CFB biomass boiler can burn wood, rice husk, bagasse, straws, palm oil kernel, etc. Biomass circulating fluidized bed boiler design This biomass circulating fluidized bed boiler is designed
