Natural gas power plants generate electricity by burning natural gas as their fuel.There are many types of natural gas power plants which all generate electricity, but serve different purposes.All natural gas plants use a gas turbine natural gas is added, along with a stream of air, which combusts and expands through this turbine causing a generator to spin a magnet, making electricity.
The thermal power plant consist several risk and hazard in their various part of plant and its operational processes.This may cause harm to people, property and environment.Those hazards are for example coal dust explosion in the coal storage area and coal mill where fine particles of the coal present may occur when.
Ring-roll bowl-mill and ball-race mills comprise the majority of coal pulverizers currently in service at power generating facilities.Figure 3 shows a cut-away of a ring-roll type coal pulverizer.In this design the grinding.The power plant installed one assembly on each of the 30 pulverizers in its facility.The plant currently changes.

Thermal efficiency of a thermal power plant is the ratio of electrical energy generated to the chemical energy of fuel consumed.For a subcritical plant it is below 42 for a new plant.What a plant is generating is the plant utilization factor.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis.The balls which could be of different diameter occupy 30 -50 of the mill volume and its size depends on the feed and mill size.
