摘要： This invention relates to an in-ash unburned component estimating device for a coal-fired furnace which monitors the density of in-ash unburned component contained in burning waste gases to operate the furnace efficiently. The object of the invention is to infer and estimate from the current situation by a simple means the density of in-ash unburned component in the burning exhaust gases that affects the combustion efficiency. A furnace temperature, a load band in the furnace, a furnace contamination coefficient, a ratio of two-stage combustion air supplied to the furnace, and a coal mixture ratio are taken in as fuzzy quantities to infer fuel ratio data and correction data used to correct predetermined reference values of reference in-furnace temperature distribution, reference in-furnace air ratio distribution and reference powdered coal grain diameter distribution. The reference values corrected by the correction data and coal reaction rate data determined from the fuel ratio data are used to calculate the density of in-ash unburned components in the burning waste gases.

摘要： This invention relates to a combustion control apparatus for a powdered coal-fired furnace that monitors noxious substances contained in burning waste gases, unburned substances in ash and power data of a pulverizing mill in order to operate the combustion furnace safely and efficiently. The combustion control apparatus infers from the current states optimal control amounts― that will keep in the minimum allowable ranges the noxious nitrogen oxides and the in-ash unburned substances that affect the combustion efficiency―and thereby controls the combustion furnace with good stability. The combustion control apparatus qualitatively evaluates as fuzzy quantities the density data of nitrogen oxides contained in exhaust gases and of unburned substances in the ash and power data of the pulverizing mill. Based on the evaluation result, a fuzzy inference is formed to determine the optimum control amount of two-stage combustion air ratio for minimizing the nitrogen oxides and also the optimum control amount for a fine/coarse grain separator to extract powdered coal of a grain size most effective for minimizing the unburned substances in the ash.
