ABSTRACT:
A process and apparatus for generating electricity from coal comprising a vertically stacked, three-stage combustor in which a sorbent is calcined in a calciner zone of the combustor and transferred to a carbonizer zone disposed below the calciner zone, coal introduced into the carbonizer zone is carbonized, producing char and spent sorbent, both of which are transferred to a combustor zone disposed below the carbonizer zone, in which the char is combusted at a substoichemetic air-to-coal ratio, producing a fuel gas. The fuel gas is cleaned and combusted in a turbine combustor, producing a flue gas which is introduced into a gas turbine for producing electricity.
