Coalfired boilers are mainly operated at either subcritical or supercritical conditions. From a thermophysics 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 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

They concluded that the ammonia/coal cofiring technology for coalfired boilers has high feasibility. In summary, current research on ammonia/coal cofiring is mainly focused on NOx emissions, boiler system operation analysis, and simulation calculations, with a lack of systematically experimental data analysis for ammonia/coal cofiring.

Moreover, IGCC plants cannot operate with such a wide variety of fuels as in CFB boilers. Another drawback of IGCC technology in relation to CFB technology is reliability. In the case of IGCC plant, the annual availability is in the range of 8085% on coal versus approximately 9092% for coalfired CFB boiler.

Pulverised coal (PC) combustion is the most widely used technology for utilityscale power generation in the world. In PC boilers, coal is ground into fine particles (∼100 μm) and then injected with heated combustion air through a number of burners into the lower part of the furnace. Particles burn in suspension and release heat which is ...

Abstract The share of coal generation in the global electricity production remains stable and prevails over other primary energy sources. A decrease in the coalfired power generation in some EU countries and the United States is balanced by its stable growth in Asia (China, India, Indonesia, South Korea) and Africa (South Africa). In 2021, global coal generation increased by 9% to a new all ...
