Emissions Control

REI takes an integrated approach to pollutant emissions from combustion sources. We continue to innovate and develop new models and modeling tools in the areas of NOx, SO2, and mercury. We put our modeling tools to work for clients, solving problems in a variety of industrial applications. REI has modeled over 100 different utility boilers firing a range of fuels including coal, oil, gas, biomass, syngas, TDF and blends of these fuels. Types of systems modeled include arch-fired, cyclone-fired, roof-fired, tangential-fired, turbo-fired and wall-fired units. REI’s primary expertise is in pollutant formation (e.g., NOx control), but we also have experience with furnace performance and operational impacts. REI is also involved with developing next-generation models to evaluate the performance of Air Pollution Control Devices (APCD) downstream of boilers. A major focus here is the behavior of mercury, sulfur oxides and particulates as combustion products move from the boiler to the stack. Components studied include SCR, ESP, scrubbers and baghouses.  In addition to the utility industry, REI provides research and consulting services for industrial furnaces (including applications in the steel, aluminum, and glass industries), incinerators, rotary kilns, smelters, and stokers.

REI also has extensive experience with on-site experimental programs in the area of emissions control.  From program planning to demonstration management and data analysis, REI’s skilled engineers can help in every stage of a testing campaign.  REI has investigated emission control from lab-scale up to pilot- and full-scale demonstrations.
