Instead of pulverizing the coal and burning it directly as fuel in the steamgenerating boiler, the coal can be first gasified (see coal gasification) to create syngas, which is burned in a gas turbine to produce electricity (just like natural gas is burned in a turbine).
The powdered coal from the pulverizer is directly blown to a burner in the boiler. The burner mixes the powdered coal in the air suspension with additional preheated combustion air and forces it out of a nozzle similar in action to fuel being atomized by a fuel injector in modern cars.
The coal received by the plant from the mine varies widely in size. It is necessary to make the coal of uniform size before passing the pulverizer for efficient grinding. There is excessive wear and tear of the fan blades as it handles air and coal particles. 2. Central or Bin System: The pulverized coal is carried from the pulverizer . Get Price

Dec 09, 1986· Such systems generally pneumatically transport the coal from a pulverizing mill to a bin after which this air is vented. The air that is then used to transport the coal from the bin to the burners is heated and often is hotter than that achievable when the same air is used to convey the pulverized coal directly from the mill to the burners.
