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.
Secondary Air Circulating Steam Boiler.This type of heater is delivered as a whole, and is installed on site, it only needs to connect thermal gas(oil) piping and electricity to start operation. The heater has four heating areas: furnace radiation heating area, the first convection tube bundle heating area, the second convection tube bundle

Primary air ( pa fan) and Secondary air fan have an important role to play in fuel combustion and must be provided in different ratios according to the fuel quantity. PA or Primary Air fans are important item in a thermal plant ( boilers) as it lifts and carry coal to destination.
May 10, 2011· What is claimed is: 1. A secondary air flow biasing apparatus for a circulating fluidized bed combustion system, comprising: a sorbent feed path configured to convey processed sorbent particles to a circulating fluidized bed furnace chamber by utilizing a portion of secondary combustion air supplied to the circulating fluidized bed furnace chamber; a first air injection port disposed within a
A dynamic model for a solid fuel fired circulating fluidized bed boiler (CFB) is presented. The model consists of the air-flue gas and the water-steam systems combined together. The Air-flue gas system includes a furnace model describing combustion in a circulating fluidized bed and a convection section describing heat transfer from hot flue
Difference between Primary & Secondary Heat Transfer Surfaces of a Boiler A boiler in every power plant is a type of heat exchanger. Heat from the combustion of fuel in the combustion chamber is transferred to the feed water circulating inside the boiler which ultimately evaporated to form steam which is utilized in a steam turbine attached to
