| 摘要 |
A combustion apparatus is disclosed wherein a main combustion chamber is provided at one end thereof with an auxiliary combustion chamber adapted for the combustion gas produced therein to flow spirally into the main combustion chamber, air is supplied to the auxiliary combustion chamber in an amount approximating the theoretical value based on the amount of the fuel supplied so as to ensure complete combustion in the auxiliary chamber, the fuel supplied into the main combustion chamber is mixed with the combustion gas coming from the auxiliary combustion chamber so that the resultant mixture, on combustion, produces a reducing atmosphere and this atmosphere is forwarded in the direction of the downstream side of the main combustion chamber, and the reducing combustion gas is completely burned by air introduced on the downstream side.
