摘要： PROBLEM TO BE SOLVED: To provide a control method and a control device for a boiler capable of improving the controllability of the temperature of the steam by controlling the water injection volume to the steam and reducing the concentration of nitrogen oxide gas in an exhaust gas. SOLUTION: Whether a detected room temperature as a temperature of a first collecting cell is within a target room temperature range or not is determined, and whether the target water injection volume is more than a standard water volume or not is determined. An operating state of the boiler is judged on the basis of results of determinations, and at least one of a circulation flow rate of a heat medium and the heat transfer volume from the heat medium to the steam is controlled in accordance with each operating state. When the detected room temperature is outside of the target room temperature range, the temperature of the first heat collecting cell is controlled to be within the target room temperature range, when the detected room temperature is within the range of target room temperature, and the target water injection volume is more than the standard water volume, the control is performed to make the detected water injection volume be close to the target water injection volume, and when the detected room temperature is within the target room temperature range, and the target water injection volume is less than the standard water injection volume, the control is performed to make the detected steam temperature and the target steam temperature be close to each other.

摘要： PROBLEM TO BE SOLVED: To provide an air nozzle structure of a fluidized bed furnace capable of largely reducing cost for repairing an air nozzle, by reducing a replacing frequency by lengthening the service life, by reducing the replacing frequency by lengthening the service life by largely reducing wear and tear of a nozzle cover, by relieving a collision of a surrounding flowing medium to the nozzle cover when supplying air in a fluidized bed.
SOLUTION: This air nozzle structure supplies air in the fluidized bed 2 from an air jetting port 7a of a nozzle body 7 installed in respective air supply holes 5 of a dispersion plate 4 for partitioning the fluidized bed 2 and a flowing air introducing part 3 under its fluidized bed. The nozzle body 7 is formed in a circular shape of opening the lower end, and has the air jetting port 7a in an upper part. The nozzle body 7 is attached with the nozzle cover 8 for covering the periphery except for a lower end part of the nozzle body 7, and the nozzle cover 8 is composed of a substantially cylindrical body of opening the lower end and gradually expanding a diameter toward the lower end.

摘要： PROBLEM TO BE SOLVED: To accurately control combustion and to suppress generation of harmful substance such as CO by identifying system characteristics of a combustion furnace between a control amount and an operating amount on-line, and controlling the furnace according to the manipulated variable corresponding to the controlled variable predicted by the identified model. SOLUTION: A fluidized bed furnace 2 fluidizes flowing medium by supplying primary air to a wind box 2 by a primary air blower 7. Material to be incinerated such as, for example, refuse is continuously introduced into a flow layer 3 by a dust supply unit 6 to gasify and burn the refuse, and unburnt gas generated by this is completely burnt by supplying secondary air by a secondary air blower 9 to a free board 4. An amount of the introduced refuse is regulated by a rotational speed of the unit 6. In this case, system characteristics of the furnace between the controlled variable and the manipulated variable are identified on-line, the controlled variable is predicted by the identified characteristics between the controlled variable and the manipulated variable, and the furnace is controlled according to the operating amount corresponding to the predicted control amount.

摘要： PROBLEM TO BE SOLVED: To improve control performance of a combustion furnace and to maintain stability of a control part. SOLUTION: System characteristics between a control amount and an operation amount of a combustion furnace are identified on-line by a model identifying part 32. By using a model obtained by the model identifying part 32, a control amount is predicted by a prediction control part 34, and a control amount is decided so that a predicated control amount gradually approaches a target value along a reference track. In a so formed method of controlling adaptation prediction of the combustion furnace, from a result of gradually identified system characteristics between a control amount and an operation amount, the change of the system characteristics is evaluated on-line in a control part parameter control 40 by the representative pole of a transfer function or a system characteristic parameter equivalent thereto, and based on the evaluation, the parameter of the prediction control part is regulated.

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.
