Measurement of Gas Species, Temperatures, Coal Burnout

Jun 25, 2009 · Measurements were performed on a 200 MWe, wall-fired, lignite utility boiler. For different overfire air (OFA) damper openings, the gas temperature, gas species concentration, coal burnout, release rates of components (C, H, and N), furnace temperature, and heat flux and boiler efficiency were measured. Cold air experiments for a single burner were conducted in the laboratory.

Development of Co-Firing Method of Pulverized Coal and

emissions from coal-fired power plants. Not only CO 2 emissions but also ash accumulation in the furnace, ash disposal, and sulfidation corrosion can be reduced by changing part of the fuel used in a coal-fired power plant from coal to ammonia. However, doing so raises some concerns regarding boiler performance, such as

Optimising fuel flow in pulverised coal-fired boilers

Jan 25, 2016 · Poor pulverised fuel (PF) distribution to the burners in a coal-fired boiler reduces combustion efficiency, increases wear of equipment and emissions, and so is bad for the economics of a plant. In her new report for the IEA Clean Coal Centre, Optimising fuel flow in pulverised coal and biomass-fired boilers, Dr Maggie Wiatros-Motyka explains that
