Steam production structure and the steam boiler also used hot water boiler

摘要

Disclosed is a waste fuel utilization type of hot water boiler, to provide steam production structure that enables the steam production that can be used as the heat transfer medium is not hot water only. A steam producing structure 10, the pressing portion 1, high pressure water P raw water W is a vapor raw material is pressurized, the heating part 3 to the high-pressure hot water Y by heating the pressure water P, a high pressure hot water Y is a structure consisting of the steam generator 5 which turn into steam V, the heating unit 3 and the steam generator 5 as a heat source, to use the heat ΔH that is produced in the combustion section 9 of the hot water boiler 8 is constructed. .BACKGROUND 2
