ABSTRACT:
The present invention provides a system and method (1) for reducing the amount of air toxic elements, particularly mercury (16), in concentrations down to and including trace levels, from a flyash (2) laden combustion gas stream (4). The method includes a step of combusting a fuel (14), often coal or solid waste to form flyash, and a step to concentrate the interaction of the flyash (2) in the combustion gas stream (4) for use as a sorbent.
