04/19/23 15. Steam Theory. • Within the boiler, fuel and air are forced into the furnace by the burner. • There, it burns to produce heat. • From there, the heat (flue gases) travel throughout the boiler. • The water absorbs the heat, and eventually absorb enough to change into a gaseous state - steam.
20. 13.1.Fineness Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the …
THERMAL POWER STATIONS Introduction Thermal energy is the major source of power generation in India. More than 60% of electric power is produced by steam plants in India. India has large deposit of coal (about 170 billion tonnes), 5th largest in world. Indian coals are classified as A-G grade coals.
