This paper analyzes the use of low-oxygen enrichment in boilers, in terms of operational and economical impact. A literature review of the impact of oxygen in coal-fired systems is presented. Several technological solutions for the low-oxygen enrichment operation are proposed and accompanied by numerical simulation results.Learn More
Most coal fired power station boilers use pulverized coal. This technology is well developed, and there are thousands of units around the world, accounting for well over 90% of coal fired capacity. The coal is pulverized to a fine powder, so that less than 2% is +300 micro meter (μm) and 70-75 % is below 75 microns, for a bituminous coal.Learn More

Field testing of Rich Reagent Injection (RRI) was recently completed in Ameren UE's Sioux Unit 1, a 500 MW cyclone-fired boiler that was recently retrofit with overfire air (OFA). This was the second of two demonstrations of RRI, the first being in Conectiv's B.L. England Unit 1, a 130 MW single wall fired …Learn More
A series of laboratory experimental results are presented on fireside corrosion in environments representing air-, and oxy-fired conditions, and with coal and/or biomass as the fuel. The effects of fluctuating reducing atmospheres and heat flux effects were examined. A variety of boiler corrosion probes and sensors were developed and tested.Learn More

While satisfactory for applications such as these, this particular definition of boiler efficiency can result in substantial errors when used for computing unit performance. Sample calculations are presented for a 600 MW coal fired unit which show errors in net unit heat rate of 1 to 3 percent due to inconsistent definitions for boiler efficiency.Learn More

PCB and PAH emissions levels were comparable or lower than levels reported in the literature for industrial-scale FBCs. VOC concentrations were low except for benzene, for which the concentration was higher than that reported for utility-scale FBC and pulverized coal-fired boilers. In addition, CO concentration was high at 1200 to 2200 ppm.Learn More
