摘要： PROBLEM TO BE SOLVED: To provide a characteristic analysis method for a circulation fluidized bed boiler capable of effecting a more correct dynamic characteristic analysis on a circulation fluidized bed boiler having as a primary element an ash circulation system, particularly a circulation fluidized bed boiler holding a fluidized bed comprising circulation ash having a feature of a complicated thermal behavior and using a medium temperature cyclone. SOLUTION: In a circulation fluidized bed boiler holding a fluidized bed and having a medium temperature cyclone, an ash circulation characteristic formula that represents waste time and delay in a passage from the time when ash discharged out of a boiler furnace and including an unburned matter is collected by the medium temperature cyclone until the time when the collected ash is recharged into the furnace or information on quantity of the unburned matter in the circulation ash is taken in for analysis. An equation applied by an exponent (n) as a power to an ash flow rate passing through a heat transfer face is used to energy balance, and matching to an analysis target boiler is made by adjusting the exponent (n).

摘要： PROBLEM TO BE SOLVED: To suppress CO and NOx in an exhaust gas by a real-time calculation of a setting value of a gas temperature at the exit of a refuse incinerator on the basis of a measurement signal in the refuse incinerator and a gas temperature distribution model in the refuse incinerator, in combusting refuse in the refuse incinerator. SOLUTION: Refuse is fed to a refuse incinerator 10 from a refuse feeding port 11 by means of a refuse feeding equipment 12. When primary air is supplied to a wind box 14 through a primary air supply tube 13, refuse is gasified and combusted at a fluidized bed 15 and the resultant uncombusted gas is completely combusted in a freeboard 16. At this occasion, a setting value of a gas temperature at an incinerator exit is calculated on the basis of a measurement signal in the refuse incinerator 10 and a gas temperature distribution model in the incinerator, so that a gas temperature measured by a thermometer 24 and a gas retention time in the incinerator can be maintained within a given range. Subsequently, combustion conditions of the refuse incinerator 10 are controlled so that the exit gas temperature nears the setting value of the exit gas temperature. Thus, stable combustion of the refuse in the refuse incinerator 10 can be achieved.
