Document Type and Number:
WIPO Patent Application WO/2019/176119
Kind Code:
A1
Abstract:
A boiler facility (20) comprises: flow path formation equipment (21, 22) forming a flow path through which there flows an exhaust gas that has been discharged as a result of the combustion of a fuel; a first heat exchanger (23) that is disposed inside this flow path; and a second heat exchanger (24) that is disposed inside this flow path and that is arranged further upstream in the exhaust gas flow than the first heat exchanger (23) is. The first heat exchanger (23) includes an outer surface that has stronger anti-corrosion properties than the second heat exchanger (24) does with regard to an acidic condensation, which is an acid produced when a component contained in the exhaust gas forms condensation.
