WASTE INCINERATING FURNACE FOR BURNING SLUDGE TOGETHER WITH WASTE

PROBLEM TO BE SOLVED: To treat sludge stably together with waste by a method wherein sludge, transferred by a sludge hopper conveyor provided below a sludge receiving hopper, is shifted into the waste charging hopper for a waste incinerating furnace. SOLUTION: Sludge to be treated is not thrown into a waste pit, but is stored directly in a sludge receiving hopper 1, then, is transferred into a sludge supplying pump 3 by a sludge hopper conveyor 2. Then, the sludge supplying pump 3 sends the sludge into a waste charging hopper 5 by pressure through a sludge shifting pipeline 7 while drying and solidifying preventive water 8 is supplied to the inlet port of the sludge supplying pump 3 and the sludge shifting pipeline 7 so that the sludge is not dried and solidified on the way of the sludge shifting pipeline 7 so as to close the pipeline 7, in this case. Further, the sludge is pumped into the waste charging hopper 5 through the sludge shifting pipeline 7 and immediately before entering the waste charging hopper 5, a partitioning valve 6 is opened and closed to switch a charging passage whereby the sludge is treated while selecting a waste incinerating furnace 4, in which the mixture of waste and sludge is burnt.
