Adjusting method capable of improving boiler load response rate

The invention discloses an adjusting method capable of improving the boiler load response rate. If a boiler is in the variable load condition and the fuel is adjusted according to the steady coal amount, the boiler load response time is too long. The method comprises the steps of predetermining the range of the coal amount which should be supplied, the mill-inlet coal amount limit value and the mill-outlet powder amount limit value in the variable load working condition; taking the mill-inlet coal amount limit value as the boundary line, dividing the coal amount which should be supplied into the front stage and the rear stage; within the range of the mill-inlet coal amount limit value, adjusting the mill-inlet coal amount so as to meet the requirement of the coal amount feedforward at thefront stage of the coal amount which should be supplied; outside the range of the mill-inlet coal amount limit value and within the range of the mill-outlet powder amount limit value, keeping the coal-inlet coal amount unchan
