Discussion on gasifier load

The load of the vaporization furnace is generally determined based on the coal feeding rate; some units use the frequency controller of the coal slurry pump, with a frequency of 78. What is the corresponding coal feeding rate? . . . . . . .
You haven’t specified the speed of the slurry pump, nor its capacity, nor the density of the slurry. So how do you expect people to calculate it for you?
The load of the gasifier should be calculated based on the gas production volume, rather than the amount of coal slurry; the gas production volume is determined by working backwards from the amount of products at the downstream stage.
The percentage of rotation speed for each slurry pump corresponds to its actual rotation speed, and the rotation speed is related to the flow rate of the slurry pump. This curve and data table are obtained from the commissioning data during the calibration of the slurry pump. If no trial operation calibration has been carried out, the values are determined based on regular operational data; the high-pressure coal slurry pumps used by different units are not necessarily identical.
