Description
Experiments of pressurized fluidized bed coal gasification in our pilot at a coal feed rate from 500 to 1, 500 kg/h were conducted. Comparing the char gasification rate per unit volume of a fluidized bed and methane yield between the upper gasifier of the pilot plant and the previous bench scale apparatus at a coal feed rate of about 6 kg/h, the char combined gasification rate per unit volume in the bench scale apparatus was 3 to 4 times larger than that in the pilot plant.<BR>Then, the char combined gasification rate in the upper gasifier of the pilot plant calculated with a two-phase model that assumed perfect mixing of gas and solid in the emulsion phase and gas plugging flow in the bubble phase was the same as that in the previous bench scale apparatus.<BR>Despite the scale difference, arranging the methane production rate for the methane yield, the methane yield in the bench-scale was the same as that in the pilot plant.
