- introducing an about 40% to about 55% by weight aqueous solution of one or more halogen precursors into the combustion chamber;
- and
- introducing a sorbent having a mean particle diameter of less than 15 μm into an exhaust stream resulting from burning of the heavy metal containing fuel in the combustion chamber.
