In the Topping Cycle, coal is partially gasified in an airblown spouted bed gasifier operating at elevated pressure (Figure 1).Sorbent is also injected into the gasifier to retain sulphur which would otherwise be released in the gas. The fuel gas from the gasifier is passed to a filtration unit, to remove solids and then burnt in the combustor of a gas turbine to generate power.

20. Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...
