Selective catalytic reduction reactor integrated with condensing heat exchanger for multiple pollutant capture/removal

摘要

A system is disclosed for minimizing equipment and flue fouling for any boiler, turbine, or combustion process in which heat recovery is advantageous and pollutant removal is necessary. The process uses an SCR located upstream of a condensing heat exchanger and maintains the temperatures in the flue gas duct such that ammonia slip and ammonium salt products are collected only on the heat exchanger surfaces which are periodically washed with water and this wash water being collected.
