Coal-Fired Boiler - an overview | ScienceDirect Topics

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.

NPPD to Convert Coal Boiler to Use Hydrogen Fuel

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 unburned carbon are lower when compared to coal firing, about 1% for …

How coal-to-gas conversion is gathering pace in the US and

since natural gas contains no Particulate Matter (PM), the PM emissions are virtually zero other than "background" PM present in the combustion airflow or that which is swept from the boiler. Regarding NOx, natural gas contains low fuel-bound nitrogen content and requires lower excess air …
