Question

Is burning of coal a Thermal reaction?​

Answer 1

Answer:

The 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

Answer 2

$\huge\mathbb{Answer}$

The coal charge and the gasifying medium move in opposite directions, or countercurrently. At the operating temperature of about 980 °C (1,800 °F), the oxygen reacts with coal to form carbon dioxide, thereby producing heat to sustain the endothermic steam-carbon and carbon dioxide-carbon reactions.
