Method for increasing capacity of raw coal hopper

The invention discloses a method for increasing the capacity of a raw coal hopper, which comprises the following steps of: installing a heavy hammer material level indicator on the raw coal hopper for acquiring the material level data information of the raw coal hopper in real time, installing a weighing type coal feeder on the raw coal hopper for acquiring the real-time coal feeding quantity data information of the coal feeder in real time, marking the moment A as the initial moment, recording data information X of the material level of the raw coal hopper at the moment A, marking the moment B as the last moment, and recording data information Y of the material level of the raw coal hopper at the moment B. By means of the method for increasing the capacity of the raw coal hopper, real-time measurement of the constantly-changing actual capacity of the raw coal hopper is successfully achieved, the problem that the combustible time of fire coal stored in the raw coal hopper cannot be calculated is solved, the a
