Combustion of some Thai agricultural and wood residues in a pilot swirling fluidized-bed combustor
This paper reports a comparative study of burning Thai rice husk, sunflower shells and fine rubberwood sawdust as well as co-firing of the sawdust and shredded eucalyptus bark in the swirling fluidizedbed combustor (SFBC). All experiments for firing individual fuels were performed for the combustor heat input of ∼300 kWth. However, in the co-firing tests, the fuel mixture was delivered at a fix...
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 کاملCharacteristics of distinct ash flows in a biomass thermal power plant with bubbling fluidised bed combustor
Characteristics of biomass used as fuel and distinct ash flows in a thermal power plant with BFBC (bubbling fluidised bed combustion) technology were studied. An integrated approach involving chemical composition, microscopy analysis, mineralogy, and thermal behaviour were used to characterize the ash. The ashes have a low unburned content, typically below 3 wt.% (dry basis), with higher values...
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 کاملEmissions modeling of fluidised bed co-combustion of poultry litter and peat.
Gaseous emissions from the fluidised bed co-combustion of 50% w/w chicken litter and peat were monitored and recorded. Emission data were used to create a dispersion model for a proposed site on a poultry farm in Ireland. Variables within the combustion unit influenced both combustion and emission levels of pollutants such as SO(2) and NO(x), CO. Concentrations of atmospheric pollutants decreas...
