Application 1271/KOLNP/2004 published 2006-05-05, filed 2004-08-31
A sorbent conditioning and direct feed apparatus is provided for direct feeding of a conditioned solid sorbent to a combustor 12. The sorbent conditioning and direct feed apparatus includes raw solid sorbent storage means 102, particle size reducing means 112 for reducing the particle size of solid sorbent supplied thereto from a relatively larger coarse particle size to a relatively smaller fine particle size, metering means 108 for metering the supply of raw solid sorbent from the raw solid sorbent storage means to the particle size reducing means 112, and transport means 118 for transporting solid sorbent which has been conditioned by the particle size reducing means 112 to the combustor 12, whereby conditioned solid sorbent is fed to the combustor 12 without any intermediate storage of the solid sorbent between the raw solid sorbent storage means 102 and the transport means 118.
