Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Fluidized Bed Combustors for Biomass Boilers - AS

Fluidized-bed boilers are the most common type of boilers recommended for biomass fuel. The fuel is suspended by an upward flow of combustion air through a bed of hot, inert particles, allowing oxygen to reach the combustible material more readily.

What is boiler | Types of boiler | How does a steam boil

Jan 15, 2019· The fluidized bed combustion takes place at a temperature of 840°C to 950 °C. Since the temperature is below the ash fusion temperature, melting of ash and associated problems are avoided. There are three types of fluidized bed combustion boilers: 1. Atmospheric fluidized bed combustion system (AFBC) or Bubbling fluidized bed combustion (BFBC)

Fluidized Bed Boilers Video - Convergence Traini

Fluidized bed boilers have high efficiencies and produce lower emissions. What materials are used for fuel in fluidized bed boilers? Fluidized bed boilers can burn a variety of solid fuels, including, coal, bark, sludge, wood chips, and tire derived fuel (TDF). Oil or gas can also be used as supplemental fuel or during startup and upset conditions.

Fluidized Bed Combustion - an overview | ScienceDirect Topi

Fluidized Bed Combustion. FBC enables the capture of acidic pollutants without resorting to scrubbers, although as with pulverized coal combustion, both bottom ash and fly ash are formed the lower combustion temperature, and the presence of the sorbent in the ash results in a product with substantially different properties.

Fluidized Bed Boiler - an overview | ScienceDirect Topi

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.

Fluidized Bed Combustion | Fluidized Bed Boiler |F

Fluidized Bed Combustion (FBC Boiler) “Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.”. A bed of solid particles is said to be fluidized when the pressurized fluid (liquid or gas) is passed through the medium and causes the solid particles to behave like a fluid under certain conditions.. Fluidization causes the transformation of the state of solid
