COAL HANDLING SAFETY - AMETEK Land

everywhere that coal is handled, processed or stored. Safe coal handling practices are designed to ensure that the fuel remains intact throughout its journey from the mine until the point at which it is ignited in the boiler. It takes as little as 1.4 kg (3 lbs) of pulverised coal in 28 m3 (1,000 ft3) of air to form an explosive mixture.

COAL BASED THERMAL POWER PLANTS: COAL

A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer, the output will be higher than base capacity, and below 50 HGI, the output will be lower. The total moisture in coal has a high effect on mill output.
