A short note: Effects of fludisation number and total air factor on the Combustion of Municipal solid waste of high moisture content in a fluidised bed

摘要

Combustion behaviour of municipal solid waste in a fluidised bed was studied. The effect of fluidisation number and total air factor on the combustion behaviour of municipal solid waste of high moisture content in a fluidised bed combustor was investigated. The first part of the combustion study was carried out at fluidisation numbers ranging from 5 to 7 U_(mf) with a fixed Primary Air Factor (AF) of 0.8. Results show that the optimum fluidisation number is 5 U_(mf) in which the bed temperature sustained longer. The second part of the study dealt with the effect of secondary air on the bed combustion behaviour conducted at 5 U_(mf). The chosen range of secondary air factor is 0-0.6. It is revealed that the addition of secondary air has no effect on the bed combustion.
