Co-firing straw and coal in a 150-MWe utility boiler: in situ measurements

Impact of coal fly ash addition on ash transformation and deposition in a full-scale wood suspension-firing boiler

“…(1), where kaolinite reacts with alkali chlorides forming alkali-alumonisilicates and HCl. Similar reactions between different vaporized alkali species and aluminosilicates have been observed in a number of studies dealing with co-combustion of coal and high-alkali fuels [65][66][67][68] as well as fundamental investigations on different aluminosilicates-sorbents for capturing alkali vapors [51][52][53][69][70][71][72]. According to Fig.…”

Deposit formation and emissions from co-firing miscanthus with Daw Mill coal: Pilot plant experiments

“…[6]. Co-firing of coals from various sources: Colombia, UK and Poland were investigated by several researchers in a number of studies [7,4,[8][9][10][11], and a wide range of biomass e.g., sawdust, sewage sludge, RDF, switchgrass, wood chips and straw were studied by others [4,12,13]. Co-firing on a commercial scale has been trialled in over sixteen countries [14].…”

Ash Deposition in Biomass Combustion or Co-Firing for Power/Heat Generation

“…To date, more than 150 coal-fired power plants (mainly 50-700 MW e ) around the World have adopted or tested co-firing of coals with woody biomass or waste materials [92]. Biomass co-firing systems can also be used for agricultural applications such as electricity and steam generation in the sugar cane industry [32], and in utility-scale (e.g., 150 MW) electricity generation [93]. Owing to the capability to meet diversified needs, biomass-based power generating systems are so far the only non-hydro renewable source of electricity that can be used for base-load electricity generation.…”
