Abstract

To achieve a high degree of heat recovery by decomposing surplus ammonia present on the downstream side of a denitrator in an exhaust gas boiler while preventing the deposition of acid ammonia sulfate on low temperature heating tubes, an exhaust gas boiler includes a residual ammonia decomposer which is disposed at a location downstream of the denitrator and between two divided high pressure evaporators.
