WebThe burning of coal can produce combustion gases as hot as 2,500 °C (4,500 °F), but the lack of materials that can withstand such heat forces even modern power plants to limit steam temperatures to about 540 °C (1,000 °F)—even though the thermal efficiency of a power plant increases with increasing operating fluid (steam) temperature.
