Estimates of Emissions from Coal Fired Thermal Power

between 0.80.9 kg/kWh, seven plants use between 0.9- 1.0 kg/kWh, and at three plants - coal usage exceeds 1.0 kg/kWh. Hence the efficiency of the plants and the coal usage per unit of electricity generation also differ at each plant. There is a need to modernize India's thermal power plants and reduce the coal usage per unit of

Natural Gas Fired Boilers

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and
