Power generation from Refuse Derived Fuel (RDF) is an attractive utilizatio
n technology of municipal solid waste. To explain the behavior of RDF-fired
fluidized bed incinerator, the commercial size RDF was continuously burnt
in a 30 x 30 cm bubbling type fluidized-bed combustor. It was found that 12
kg/h of RDF feed rate was too high feed for this test unit and the CO leve
l was higher than 500 ppm. However, 10 kg/h of RDF was a proper feed rate a
nd the CO level was kept under 150 ppm. Secondary air injection and changin
g air ratio from the pipe grid were effective for the complete combustion o
f RDE. It was also found that HCl concentration in flue gas was controlled
by the calcium component contained in RDF and its level was decreased with
decreasing the combustor temperature. (C) 1999 Elsevier Science Ltd. All ri
