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.
Northern States Power`s cyclone-fired 550 MW Allen S. King Station, which cofired wood residues with subbituminous coal from 1987 to 1997, is the longest operating biomass cofiring plant in the
Many plants across the nation have considered or actually begun converting from coal to biomass, either as part of a co-firing strategy combining biomass and coal or as a biomass-only setup. In 2011, one producer got ahead of the curve by implementing a biomass conversion at a decommissioned coal-burning power plant.
An approach that may increase the use of biomass energy in the short term is to mix it with coal and burn it at a power plant designed for coal—a process known as “co-firing.” Through gasification, biomass can also be co-fired at natural gas-powered plants.

With the boiler stable and operating on coal, the first modified biomass mill was placed into service on September 10, 2013. The classifier vanes were set to fully open (position “0”) for this
And Drax is far from the only coal-to-biomass project in the world, even if it is the largest. In Denmark, a coal plant in Copenhagen is set to be turned into a 100% biomass facility.
Biomass—renewable energy from plants and animals. Biomass is organic material that comes from plants and animals, and it is a renewable source of energy. Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis. When biomass is burned, the chemical energy in biomass is released as heat.
One week later, Dairyland Power announced an agreement to purchase the facility’s entire 40 MW net output from DTE upon conversion to a biomass burning plant. Between 2008 and 2010, Stoneman was converted by facility owner DTE Energy Services from a 100% coal …
Different fuels are used in the Amer power plant, the main types being hard coal and biomass, which are delivered by inland vessels and pulverised into dust prior to combustion. Biomass is supplied in the form of wood pellets, i.e. compacted pieces of sawdust.
