PROBLEM TO BE SOLVED: To mix air and steam favorably without providing an air heater, which heats air to be mixed with steam, additionally, and without causing cohesion or condensation of the steam, in a mixing/heating device which continuously supplies hot mixture to an external apparatus by mixing relatively cold air and steam and heating them. SOLUTION: The mixing/heating device (1) is equipped with a combustion area (6) which produces combustion exhaust gas by combustive reaction and regenerative heat exchangers (11 and 12) which possesses passages capable of circulating cold air and combustion gas alternately. The heat exchangers are divided into air preheating sections (11A and 12A) which heat cold air, and mixture heating sections (11B and 12B) which heat the mixture of air and steam. Steam mixing chambers (11C and 12C), which can lead in steam, are made between the air preheating section and the mixture heating section, and the air preheating section heats the cold air to a temperature not less than the temperature of the steam, and leads it into the steam mixing chamber. |
