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.
Plant Bowen, the third largest coal-fired power station in the United States. Main article: Coal power in the United States This is a list of operational coal-fired power stations in the United States .
It can be deployed in nearly all types of coal-fired boilers, including pulverized coal boilers, stokers and fluidized beds. Because stoker boilers are designed to fire fairly large fuel particles
Pollutants from coal power plants like carbon dioxide, sulphur dioxide, and nitrogen oxide can also affect the environment. Thermal power plants are the biggest producers of Carbon Dioxide. The boiler for typical 500 MW units produces around 1600 tons per hour of steam at a temperature of 540 to 600 degrees Centigrade.
as either a CFB used primarily for large coal-fired power units or a bubbling fluidized bed (BFB) used primarily for waste coal or biomass 1 Cyclone boilers are similar to PC boilers but do not require extensive fuel grinding and are used for coals, wastes, and other fuels not suitable for PC operations.
Pulverized fuel boiler: Coal is pulverized into a fine dust (about 0.1 mm in size), and is fed into the boiler in a stream of air. They are by far the most common boiler types for coal. These boilers can reach efficiencies of over 90% when they are well run. They can be …
Apr 09, 2018· Coal also is the most used fossil fuels for producing electricity as we use coal power plant for producing around 40% of the world’s electricity, and we commonly use it in cement manufacturing and industrial purposes such as refining metals. There are four main types of coal, which are formed in a similar manner both formed from decomposed vegetation composed at high …
Power plants generally use steam coal which is a grade between anthracite and bituminous. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverized coal combustion systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature.
2. According to the combustion or heat source points: coal fired power plant boiler, gas fired power plant boilers, biomass power plant boiler, oil fired power plant boiler, waste heat power plant boiler. 3.According to the medium circulation way: natural circulation boiler, forced circulation boiler, direct current boiler. 4.
Jan 15, 2019· There are two types of boilers are used in sub critical, super critical and ultra-super critical coal fired thermal power plant: Pulverized coal-fired Boiler Fluidized Bed combustion (FBC) boiler
