Welcome Mining Machinery Company
the boiler house accommodates the coal bunkers, coal feeders, coal milling plant and the forced draught and primary air fans and air heaters.the furnace dimensions are chosen to meet the requirements of low nox emissions in the flue gases whilst maximising burnout to minimise the amounts of unburned carbon-in fly-ash for the given fuel fired.in
thermal power station. thermal power stations produce electricity by burning fuel in a boiler to heat water to produce steam. the steam, at tremendous pressure, flows into a turbine, which spins a generator to produce electricity. the steam is cooled, condensed back into water, and returned to the boiler to start the process over. coal to
aug 29, 2010 pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty. however, during the design stage it is possible to make boilers firing multiple fuels. with pulverization technology, large size boilers could be designed, manufactured, erected, and run much more efficiently.

coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station. generally, bituminous coal or brown coal is used as fuel. the coal is stored in either dead storage or in live storage. dead storage is generally days backup coal storage which is used when coal supply is unavailable.
oct 13, 2020 introduction to coal handling plant. In a coal based thermal power plant, the initial process in the power generation is coal handling.so in this article will discuss the overall processes carried out at a coal handling plant in a coal based thermal power generating station.
oct 16, 2016 thermal power plant burns enormous amounts of coal. plant may require around 2000 tons of coal daily pulverising plant In modern thermal power plant coal is pulverised i.e. ground to dust like size and carried to the furnace in a stream of hot air.
sep 30, 2018 after burning of coal, of total coal consumption is converted into ash which need to be properly disposed-off from the thermal power plant. types of ash generated in thermal power plant. bottom ash ash generated below furnace of the thermal power plant is called the bottom ash. the value of bottom ash generated is around of total ash.
jan 20, 2018 coal handling plant the function of coal handling plant is automatic feeding of coal to the boiler furnace. thermal power plant burns enormous amounts of coal. plant may require around 2000 tons of coal daily following are the process of plant-: unloading process feeding process screening process crushing
coal-fired thermal power plants systems use several types of process fans. based on the size of the boiler or steamer the rating of the fan used differs and based on the type of air flow and the process involved different types of draught fans are used in thermal power plants.
At the startup of furnace besides optimising its composition; it was decided to restore selective crushing of the coal batch using pneumatic and mechanical separation in the third unit of the

plants, and it was confirmed during a long-term commercial-scale experiment that the fine crushing of high coking pressure coal decreases coking pressure and decreases the maximum power current of coke pushing. thus, the selective fine crushing of high coking pressure coal is a promising way to reduce cok-ing pressure and prolong coke oven life.
