CATALYTIC COMBUSTION HEATER

摘要

A catalytic combustion heater having, in a fuel gas flow passage in which an inflammable gas- and combustion support gas-containing fuel gas flows, tubes in which an object fluid to be heated flows, and an oxidation catalyst provided on outer surfaces of the tubes and contacting the fuel gas to generate an oxidation reaction, comprising a catalyst-carrying heat exchanger adapted to heat the object fluid with the oxidation reaction heat of the fuel gas, a detecting member adapted to detect the temperature of a combustion exhaust gas in the fuel gas flow passage to check whether the temperature is at the level of a dew point thereof or not, and a control unit adapted to control at least one of a feed rate of the combustion support gas, which is supplied to the fuel gas flow passage, and a feed rate of the inflammable gas.
