Gas heating apparatus with dual burners |
摘要 |
A gas heating apparatus has a cylindrical outer shell disposed along a duct in which a gas to be heated flows. A pre-mixture gas supply tube is connected to the outer shell. A combustion unit including a sintered fiber mat is provided inside the outer shell with a spacing being provided between outer shell and the sintered fiber mat. The combustion unit burns the pre-mixture gas on an inner surface of the sintered fiber mat. A diffusion burner is preferably provided upstream of the outer shell and of the combustion unit to increase the heating effect. With these constructions, it is possible to obtain a smaller-sized heating apparatus which produces a higher output.
