Co-firing coal with biomass is a potentially valuable tool to help decrease greenhouse gas and other emissions in coal-fueled boilers. Use of biomass at low to moderate biomass to coal ratios appears to produce the best performance enhancements and can result in overall life-cycle energy consumption reductions, as well as reduced solid waste generation.Learn More
Jan 01, 2013 · Co-firing biomass with fossil fuels in existing power plants is an attractive option for significantly increasing renewable energy resource utilization and reducing CO 2 emissions. This chapter mainly discusses three direct co-firing technologies: pulverized-fuel (PF) boilers, fluidized-bed combustion (FBC) systems, and grate-firing systems, which are employed in about 50%, 40%, and 10% …Learn More
Co-combustion is one of the most efficient way to utilize biomass in power industry. Average efficiency of biomass power plant is in the 20 to 25% which is almost half lower for the considerable coal units. In the same time biomass co-firing at a 3-5% (w/w) causes a decrease in boiler efficiency less than 1% [7]. 2.Learn More

Feb 07, 2002 · Cofiring biomass with coal is a promising short-term option for reducing the net CO2 emissions from existing coal-fired power plants. This paper examines the effects of cofiring biomass and coal on ash deposition under conditions representative of those found in the superheater region of pulverized-coal boilers. Experiments were conducted with blends of eight different fuelsthree types of Learn More
Apr 14, 2009 · The paper describes an investigation of slagging and fouling effects when cofiring coal/biomass blends by using a predictive model for large utility boilers. This model is based on the use a zone computational method to determine the midsection temperature profile throughout a boiler, coupled with a thermo-chemical model, to define and assess the risk of elevated slagging and fouling levels Learn More
Cofiring biomass and coal is a time-tested fuel-switching strategy that is particularly well suited to a stoker boiler, the type most often found at coal-fired federal facili-ties. However, cofiring has been successfully demonstrated and practiced in all types of coal boilers, including pulverized-coal boilers, cyclones, stokers, and fluidized Learn More

Biomass Co-firing for Coal-Fired Boilers Ayhan Demirba¸s P.K. 216, 61035 Trabzon, Turkey ABSTRACT In this study ground biomass and pulverized coal were used for co-firing test. The tests of co-firing of coal and biomass were carried out in a bench-scale bubbling fluidized bed combustor. Biomass is an attractive and sustainableLearn More
Dec 01, 2008 · The percentages of biomass wastes directly co-fired in power boilers vary greatly from boiler to boiler. Fluidized bed boilers are less prone to suffer from negative effects of co-firing, nevertheless for the present study the pulverized coal fired boiler is chosen for which typically these percentages do not exceed 5% on an energy basis.Learn More
