INVESTIGATING THE GASIFICATION OF SOLID FUEL IN A PRESSURIZED FLUIDIZED BED ON A LARGE-SCALE UNIT.

In order to accelerate the development and assimilation of an experimental steam-gas plant of 250 MW capacity (PGU-250) with in-cycle gasification of solid fuel, a large-scale coal gasification rig was used to carry out a series of research, adjustment and refining work on full- and small-scale specimens of main and auxiliary equipment. When selecting the method of gasification, data from both inside and outside the Soviet Union were analyzed taking into account the particular features of the organization of this process within the power-generating plant. On the basis of calculations, the results of laboratory tests and experience in operating large-capacity gas generators with a fluidized bed in atmospheric conditions, preference was given to the method of gasification in a fluidized bed. 6 refs.
