Abstract

PURPOSE:To prevent the exhaustion of unburnt materials by controlling conveyors and a blower in correspondence to the exhaustion temperature after the increase in the set speed of the transfer, in successively transferring materials to be burnt on the grate at a drying zone, a burning zone and an after burning zone. CONSTITUTION:The materials to be burnt supplied to a supply device 7 are successively transferred by conveyors 11a-11c to the drying zone A, the burning zone B and the after-burning zone C, and during this transfer, the materials to be burnt are burnt. Here, at least one of the supply device 7, conveyors 11a and 11b is controlled of its transfer speed by a control mechanism 30 in correspondence to the output of the exhaustion temperature detector 28. Upon this occasion, in the case where the measured value of the detector 28 is lower than the set range when a set time is passed, after the increase in the set speed of the material to be transferred, the transfer speed is lowered temporarily. Upon this occasion, the quantity of air blown to the drying zone A is made comparatively large by a blower 24.
