To provide a hybrid type hot air device capable of efficiently separating combustion ash from a combustion exhaust gas, functionally organized in compact as a whole, and producing hot air with high efficiency in a small installation space, with respect to the hot air device producing hot air, in particular, from the air of low temperature by utilizing combustion heat of solid fuel such as biomass fuel.
The hybrid hot air device includes a heat exchanging chamber 3 between an external casing 1 and a combustion chamber 2 inside, and includes a low-temperature air inlet and a high-temperature air outlet connected with the heat exchanging chamber 3, an intake fan for introducing the low-temperature air into the heat exchanging chamber 3, and a cyclone type combustion ash separator 4 disposed in the combustion chamber 3 and opened into the combustion chamber 3 at its upper end. The low-temperature air introduced to the heat exchanging chamber 3 is heated by heat exchange with hot air in the combustion chamber 2, and discharged as the air of high temperature, and the combustion ash separating from the combustion exhaust gas flowing into the combustion ash separator 4 and falling is taken out from an combustion ash outlet port 10, thus the hot air can be produced with high efficiency in a small installation space.
