摘要： A method for controlling combustion in a furnace into which combustible material, e.g., urban refuse, industrial waste, and a controlled quantity of combustion air are fed. The furnace includes a mixing/stirring region where unburnt gas and secondary combustion air are mixed and stirred. A part of exhaust gas derived from the furnace is blown into the mixing/stirring region depending on variation in the quantity of the secondary combustion air, and a flow rate of mixture gas consists of the exhaust gas and the secondary combustion air to be fed into the mixing/stirring region is maintained within a predetermined region so that effective combustion takes place.

摘要： In a fluidized bed incinerator for burning matter to be incinerated charged into a furance by causing fluidization of a fluidizing medium with the assistance of air fed from the lower portion of a fluidized bed, a combustion control method is arranged such that: the combustion rate of matter for incineration in the furnace is detected by a combustion rate detecting means, and, when the combustion rate exceeds a predetermined level the amount of air fed from the lower portion of the fluidized bed is reduced; and, simultaneously, the amount of air blown into a space above the fluidized bed is increased so as to control and maintain the combustion rate of the matter to be burnt in the furnace at the predetermined level and to suppress fluctuations in the amount of combustion air, the amount of exhaust gas, the oxygen concentration in the exhaust gas and the amount of gas remaining unburnt or the like. The combustion control method is also applicable to a fluidized bed incinerator constructed to include a plurality of air chambers formed at the lower portion of the fluidized bed, through which chambers the air is fed into the incinerator and the combustion rate of matter for incineration is controlled by regulating the amount of air fed from the air chamber disposed at the portion where the matter charged is dropped.
