Co-firing Performance of a Retrofitted Oxy-Combustor burning Coal/Biomass Blends: Experimental and Simulation Study
Oxy-fuel combustion is a clean coal technology based on firing fuel in an enriched oxygen atmosphere to obtain a high CO2 concentration in the off-gases. This technology can be combined with the co-firing biomass and the use of blends of coal and biomass can compensate for the fact that the gas properties in the furnace in an oxycombustion process differ from the air-firing case (oxy-firing flu...
متن کاملHydrodynamics of a fluidized bed co-combustor for tobacco waste and coal.
The fluidization characteristics of binary mixtures containing tobacco stem (TS) and cation exchange resin (a substitute for coal) were studied in a rectangular bed with the cross-section area of 0.3 × 0.025 m(2). The presence of herbaceous biomass particles and their unique properties such as low density and high aspect ratio resulted in different fluidization behaviors. Three fluidization vel...
متن کاملA model of a bubbling fluidized bed combustor oriented to char mass estimation
Fluidized bed techniques are employed in coal combustion power plants, because they allow for the use of low-quality fuel and result in low pollutant emissions. The most important dynamical difference between fluidized beds and normal combustion chambers, is that the former are characterized by a significant loading of carbon, usually absent in conventional plants. Fluidized beds are remarkably...
متن کاملEffect of co-combustion of chicken litter and coal on emissions in a laboratory-scale fluidized bed combustor
Article history: Received 1 October 2006 Received in revised form 20May 2007 Accepted 20 June 2007 Co-combustion of chicken litter (CL) with coal was performed in a laboratory-scale fluidized bed combustor to investigate the effect of CL combustion on pollutant emissions. The emissions of major gaseous pollutants including CO, SO2, H2S and NO and temperature distribution along the combustor wer...
متن کاملEffects of Biomass Share on So2 and Nox Emissions in a Circulating Fluidized Bed Combustor
In this study, effect of biomass share on co-combustion of coal and biomass in a circulating fluidized bed is investigated by previously developed model. SO2 and NOx emission predictions of the model are compared with test results obtained from the laboratory-scale 30 kW (thermal) atmospheric test unit of 0.86 m i.d. and 7 m tall riser data published in the literature. Simulation results show t...
