Working principle of steam boiler

- Nov 19, 2018-

Heating equipment (burner) to release heat, first through radiation heat transfer by the water-cooled wall absorption, cooling wall boiling vaporization, resulting in a large amount of steam into the drum for soda separation (except DC furnace), the separation of saturated steam into the superheater, through radiation, convection continue to absorb the top of the furnace and horizontal flue, tail flue smoke heat, And make the superheated steam reach the required operating temperature. Power generation boilers are usually also provided with a reheater, is used to heat the steam after the high-pressure cylinder work, the reheater out of the hot steam and then go to the medium and low pressure cylinder to continue to do the power generation.
