PROBLEM TO BE SOLVED: To provide a hot-air heating device capable of adjusting a temperature of supplied hot air to a desired temperature while securing high heating performance.SOLUTION: In a hot-air heating device 100, control means 80 determines a target supply fuel amount to be supplied to a combustor 20 within a range of the whole supply fuel amount, so that a temperature of the air supplied from a supply port 72 becomes a second target temperature on the basis of a predicted temperature rise characteristics in which a relationship between the supply fuel amount to the combustor 20 and a predicted temperature rise obtained by predicting temperature rise of the air sucked into a housing 10 from a suction port 70 in implementing combustion with the supply fuel amount during being supplied from a supply port 72, is defined in advance, and a temperature of the air measured by suction air temperature measurement means 1, when operation instruction receiving means 50 receives an operation execution instruction in a second heating operation mode, and the fuel of the target supply fuel amount is supplied to the combustor 20 by fuel amount adjusting means F. |
