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.

CO Boilers for the Hydrocarbon Processing Indust

A shop-assembled boiler modified for CO firing is shown below. CO gas is admitted through ports in the side walls and front wall to promote mixing and rapid combustion. The burners, for firing supplementary fuel, are located in a refractory front wall and fire into a horizontal furnace.

Combustion Fundamentals - Industrial Wiki - odesie by Te

The amount of air that contains enough oxygen to combine with all the combustible matter in the fuel is called the '''stoichiometric value''' or '''theoretical air'''. It is improbable for every molecule of fuel that enters the furnace to combine chemically with oxygen.

Combined cycle power plant - Wikiped

The General Electric9HA claimed 41.5% simple cycle efficiency and 61.4% in combined cycle mode, with a gas turbine output of 397 MW to 470 MW and a combined output of 592 MW to 701 MW. Its firing temperature is between 2,600 and 2,900 °F (1,430 and 1,590 °C), its overall pressure ratiois 21.8 to 1.


removed. In addition, "dry firing a boiler" (applying heat to a boiler with inadequate water inside) can result in an extremely destructive and hazardous condition caused by the rapid and potentially explosive buildup of extreme pressures and temperatures. According to the National Board Bulletin it is a good

Conversion of Existing Coal-Fired Boilers to Natural G

natural gas. Boiler efficiency decreases are to be expected in the 3% to 4% range, depending on the current fuel and boiler design. Auxiliary power demand is reduced with natural gas firing because pulverizers, primary air (PA) fans, precipitators, coal handling system, sootblowers, and other equipment are no longer required.

Fuels commonly fired in boilers include fossil, biomass, and RDFs as well as other types of fuels and fuel combinations. Coal, petroleum-based oils, and natural gas are fossil fuels commonly fired in ICI boilers.

Combine solid fuel central heating with electric boil

Feb 20, 2010· Is it possible to plumb an electric boiler into an existing solid fuel central heating system? My house is centrally heated from a solid fuel fire with a back boiler. It is a very good system and I like having a real fire. However, I would like to be able to 'set' the heating to come on at regular times in very cold weather, when my work takes me away from home for more than 24 hours and the

Steam Boiler: Solid Fuel Firing Method in Steam Boil

Author: Technical Concept Solid Fuel Firing Method in Steam Boiler. Solid fuel is one of type of fuel used in combustion process. The combustion process with solid fuel can be performed by mechanical spreader stoker or hand stoker firing. Solid fuel firing in steam boiler can be classified as underfeed stoker firing and overfeed stoker firing.
