摘要： A device for channeling boiler flue gas flow and injecting controlled amounts of ammonia upstream of a selective catalytic reduction (SCR) NOx removal system. A perforated plate and/or damper can be located within one or more channels to provide volumetric control through a channel. Flow conditioning devices such as static mixing tabs and/or flow straightening tube bundles can optionally be included in each channel to improve mixing and velocity profiles. Gas flow rate measurements made, for example via pressure taps, within one or more channels can be used to measure flow and provide feedback for improved ammonia-to-NOx mole ratio control.

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.
