Exergy analysis of supercritical CO2 coal-fired

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

Boiler Operations That Affect Efficiency. (Excerpted from Steam/its generation and use, 42nd edition) In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production).
