Impacts of wood cofiring on coal pulverization at the Shawville Generating Station

Effect of cellulose and lignin content on pyrolysis and combustion characteristics for several types of biomass

“…In order to utilize both the lowrank coal and biomass effectively as energy resources effectively, co-combustion and/or cogasification technologies have been focused recently [4]. Many researchers [5][6][7][8][9] have already studied the co-combustion characteristics of biomass with coal. Co-combustion technologies of coal with biomass have also been applied in several practical boilers to reduce CO 2 emission, fuel cost and so forth.…”

Cofiring biomass and coal for fossil fuel reduction and other benefits–Status of North American facilities in 2010

“…Results of these tests indicated the general feasibility of cofiring with wood and coal at low rates, but also revealed some challenges. For example, pulverizing wood particles for use in PC burners can pose some technical problems (Prinzing and Hunt 1998). Other studies have found that successful cofiring in PC systems requires wood particle sizes of 1/16 inch or smaller (Gold and Tillman 1996).…”

Barrier Issues to the Utilization of Biomass

“…European research into direct and cofiring biomass with coal for power generation has been fairly extensive with various agricultural biomass fuels such as wheat straw and wood waste product fuels (8)(9)(10)(11)(12)(13). In the United States, research has focused primarily on cofiring arrangements for wood (14)(15)(16)(17)(18)(19)(20)(21), and more localized agricultural waste biomass fuels have been studied less intensely (22)(23)(24)(25)(26). A recent synopsis of biomass for energy production, written by European researchers, discussed issues and barriers to using biomass such as wood for energy production (27).…”
