A two-stage reactor for studying sorbent reactivities in flue gas desulfurization systems utilizing a fabric filter collector

摘要

A two-stage reactor has proven superior in understanding the complex reactions involved in dry gas-solid reactions responsible for flue gas desulfurization in the medium temperature range(425 -640 deg. C). Traditionally, experimental approaches have concentrated on either the in-duct reactivity portion of these reactions, or the reaction in the particulate collector, usually a fabric filter (baghouse). From these current studies new have found that sorbent injection conditions upstream of a fabric filter affect the continued reactivity of the sorbent on the filter as well.
