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

COMBUSTION

Combustion takes place when fuel, most commonly a fossil fuel, reacts with the oxygen in air to produce heat. The heat created by the burning of a fossil fuel is used in the operation of equipment such as boilers, furnaces, kilns, and engines.
