Coal-Fired Boiler - an overview | ScienceDirect Topics
Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

Natural gas fired boiler installed at SAB plant - EE
The main objective was to cease the use of coal fired boilers. SAB substituted their coal fired boilers by installing two new natural gas fired boilers and converting two coal-fired boilers to natural gas with energy savings of between 13 and 32%. Natural gas was chosen because it is one of the least contaminated fuels used for boiler operation.

Conversion from coal to natural gas is not likely, unless there is extreme environmental pressure or substantial reductions in loads. 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.

Natural gas-fired electricity conversion efficiency
From 2006 to 2015, annual average heat rates of natural gas-fired electricity generators decreased 7% as heat rates of coal-fired electricity generators remained stable, increasing only 1%. Heat rates are calculated based on the amount of energy (measured in British thermal units) reported to EIA that was used to generate a unit of electricity.

Boiler Efficiency - an overview | ScienceDirect Topics
The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.
