Abstract
A control system for a pulverized coal fired boiler provided with a pulverized coal producing equipment including a coal feeding section, a milling section and a classifying section and an adjuster for adjusting a coaling rate thereof, and a pulverized coal burning equipment for burning the pulverized coal supplied from the pulverized coal producing equipment includes an estimation apparatus for estimating a coaling rate of coal out form the pulverized coal producing equipment, and an apparatus for operating the adjuster to adjust a coaling rate of coal supplied from the pulverized coal producing equipment to the pulverized coal burning equipment on the basis of an estimation of the estimation apparatus. The estimation is conducted by calculation of mathematical models which are obtained with taking the physical mechanism in the pulverized coal producing equipment and simulate a heat input with higher accuracy.
