Pulverised Fuel Mills – Power Stations of the UK

Pulverised Fuel Mills. A pulveriser or pulverised fuel mill grinds coal into a fine powder. They contain a number of steel balls inside a rotating drum, causing the balls to tumble. The coal is then in, where it is crushed between the balls. Air is blown through the drum to carry the pulverised fuel to the boilers.

Pulverised Fuel - an overview ScienceDirect Topics

The pulverizer can be a hammer mill, ring-roll mill, or a ball mill type. The ground particles and air are swept by the primary air fan and delivered to the burner as a dilute suspension of pulverized fuel and air. A combination of solid fuel materials can be fired directly or semi-directly using the system shown in Figure 6.8. Here we envision ...

UNIT-1 THERMAL POWER STATIONS Introduction

The fuel (i.e. coal) is cheaper. The cost of generation is lesser than that of diesel power plants. Disadvantages: It pollutes the atmosphere due to the production of large amount of smoke. This is one of the causes of global warming. The overall efficiency of a thermal power station is low (less than 30%).
