Abstract:
Disclosed is a coal boiler that makes it possible to reduce the height of the boiler and shorten the period of construction. The coal boiler includes a first furnace in which a combustion gas generated by burning coal and air ascends; a second furnace in which the combustion gas supplied from the first furnace flows downward; and a heat recovery area in which the combustion gas supplied from the second furnace flows upward.
