Coal Pulverising In Boilers
Why Pulverized Coal is Used in a Power Plant
· Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns. This means every particle comes into contact with the air. The loss due to unburned carbon is only in the range of % or less making the boilers very efficient. The pulverizer does the powdering or the pulverizing ...
Coal Bunker
Secondary areas such as the storage volume of coal bunkers and the type and capacity rating of auxiliary plant such as coal pulverising mills, fans, etc., are also determined by these factors and can influence some of the principal overall dimensions of the station layout, particularly the minimum boiler centreline spacing. Fig. 500 MW oilfired boiler and auxiliary plant. Fig. 500 ...
