摘要：PURPOSE:To prevent dust from being adhered to a combustion fan after water vapor contained in discharged gas forms dew in a low NOx type combustion device in which a part of discharged gas is recirculated to a combustion chamber. CONSTITUTION:A combustion fan 100 is provided with two vanes 101 and 102. One vane 102 is used for supplying combustion air to a combustion chamber and the other vane 102 is used for discharging and recirculating a part of the discharged gas into the combustion chamber. A combustion air passage and a discharging air recirculation passage are separated.
