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.
In 2013, the world’s largest 600 MWe supercritical CFB boiler developed by Chinese domestic technology successfully passed 168 h full load test and turned into commercial operation. The boiler operation data is in good agreement with the design values .
CFB boiler is the youngest and most advanced coal combustion technology with broad development space and bright future. Types of Boilers in Power Plant A power station, also referred to as a power plant or powerhouse and sometimes generating station or generating plant, is an industrial facility for the generation of electric power.
Click to view2:53Jan 30, 2018· Sumitomo SHI FW is the global leader in CFB technology and has supplied a full range of CFB boilers totaling 36 GWe in power capacity and 30 million hours of operational experience. In June 2017
Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material.
Circulating fluidized bed (CFB) boilers feature the fast fluid bed which is formed in the whole furnace (combustor), and particles are collected in a cyclone and recirculated into the furnace. Therefore higher combustion efficiency and furnace desulfurization/ denitrification efficiency than those of other types of fluidized bed boilers can be
This Section is all about AFBC and CFBC Boilers (Circulating Fluidised Bed Combustion) operation manuals. Atmospheric and pressurized Fluidised Bed Boilers design their problems. free Presentation Training material.. CFB Boilers introduction zip
The furnace cross-section heat release rate is not often used during CFB boiler design, because furnace height and cross section area are opposing factors that must be balanced. CFB boiler designers must also consider other factors. 3. Fuel. For design and operation of any boiler, including a CFB boiler, the influence of fuel is crucial.
The relevance of design and feed-stock parameters to the operation of a CFB boiler are also examined, along with their impacts on designs of mechanical components, including cyclones, air
Dec 11, 2015· Presentation on CFBC Boilers 1. Key benefits are fuel flexibility, reduced emission and lower bed temperature. 2. Different Versions Industrial boilers ore developing with gradual change in their design of different parts and to optimize the thermal efficiency, fuel multiplicity and to sustain with environmental norms, with cost effectiveness for installation operation and maintenance.
