· While PRB coal was the predominant emission efficient energy source in 1990, in 2012, it no longer reins as the most environmentally friendly fuel. With the current government crackdown on coalfired power plants, the existing plants will likely be the last. Coalfired power plants .
BOILER SYSTEM The total number of pulverizers (including one spare) and their associated power requirement is based on plant size and coal type. The 400MW plant uses five pulverizers for bituminous and PRB cases, and six for lignite; the 600MW plant uses six pulverizers for bituminous and PRB, and seven for lignite; and the 900MW plant uses
Answer (1 of 6): The basic function of a pulveriser in a Thermal Power plant is to break down and crush the coal lumps into fine particle form before it is taken to the boiler for burning. Pulverisation of coal basically breaks the big coal lumps and increases the surface area which is important ...
The two methods used to feed the pulverized fuel to the combustion chamber of the power plant: 1. Unit System 2. Central or Bin System. In unit system, each burner of the plant in fired by one or more unit pulverizers connected to the burners, while in central system, the fuel is pulverized in the central plant and then distributed to each furnace with the help of high pressurized air currents ...

· Combustion system requirements. The fineness of the coal powder and the uniformity of the coal flow sent to the burners are crucial parameters to achieve an effective combustion in coalfired power plants. Coal pulverisers or coal mills are the heart of a PCF boiler. Often, the root causes of nonoptimised combustion lie with the pulverisers.

· In power plants, where coal is used as fuel for combustion, FD fans are used as primary and secondary air fans to regulate proper combustion and maximize the fuel efficiency of the process. A typical FD fan arrangement uses inlet and outlet dampers to control and maintain the required air pressure inside the system.
Hydraulic systems should only use listed fireretardant hydraulic fluids. Automatic sprinkler or water spray systems should be employed for fire protection of coal handling structures that are critical to power generation where coal or coal dust is likely to be accumulated. Fire protection to pulverizers. Design shall be in accordance with NFPA 85.
