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 for combustion than coal. These mechanisms can contribute to low total NOx emissions that are primarily

Conversion of Existing Coal-Fired Boilers to Natural Gas

Jun 28, 2019 · After the coal is burned, heat is released, and sulfurized oxygen gas is generated, which is discharged into the atmosphere by the flue gas. These gases are very polluting the environment and cause harm to humans. The natural gas used in gas boilers is mainly composed of methane gas and contains a small amount of non-hydrocarbon gas.

natural gas. Boiler efficiency decreases are to be expected in the 3% to 4% range, depending on the current fuel and boiler design. Auxiliary power demand is reduced with natural gas firing because pulverizers, primary air (PA) fans, precipitators, coal handling system, sootblowers, and other equipment are no longer required.

Challenges when Converting Coal-Fired Boilers to Natural Gas

Apr 05, 2017 · Co-firing is a technology that uses gas burners inserted into the boiler in a way that allows both coal and natural gas to be burned at the same time.The main advantages are environmental and load control. Gas burners can be turned up and down very easily and quickly compared to coal, especially, stoker type coal boilers.
