Pulverized Coal Boiler

General. Pulverised coal (PC) combustion is the most widely used technology for utilityscale power generation in the world. In PC boilers, coal is ground into fine particles (∼100 μm) and then injected with heated combustion air through a number of burners into the lower part of the furnace. Particles burn in suspension and release ...

Pulverized Coal Power Plant ~ Coal Energy

04/01/2011 · For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverised coal is a significant dust explosion hazard, as large quantities are suspended in air for transfer from the mill to the power plant.

TOWER TYPE BOILERS VS TWO PASS BOILERS Salient Features of Pulverized Coal Tower Type Boiler: I. Recommended for highly erosive fuel. Since flue gases passes without any change in direction, the erosion rate in these types are lower. II. Supercritical units go with tower type arrangement since it can adapt to the spiral wall construction easily [1] III.
