Samenvatting:
Co-combustion of biomass or municipal sewage sludge with coal in afluidised bed installation influences the combustion behaviour and the flue
gas emissions. In the case of coal-wood and coal-straw co-combustion the
concentrations of NOx, SO2 and CO in the flue gas decreased with increasing
biomass contribution in the fuel mixture. Co-combustion of coal and sewage
sludge resulted in a substantial increase in SO2 concentration in the flue
gas upon increasing the sludge ratio. Compared with coal-firing, the
concentration of chlorine in the flue gas increased when increasing the
amount of straw or sewage sludge. No operational problems were observed with
co-firing wood and coal. In the case of straw and sewage sludge agglomeration
of the bed material occurred: adaptations of the combustion conditions are
necessary for commercial applications. Due to the relatively short time of
operation, ash agglomeration did not interfere with the completion of the
test programme. 3 figs., 4 tabs.
