|1. (WO2017175483) STOKER-TYPE INCINERATOR|
|Applicants:||HITACHI ZOSEN CORPORATION
In an incinerator (1), a thermal image pickup unit (75) acquires a thermal image of refuse on fire grates (21), and a refuse height calculating unit acquires refuse height information indicating the distribution of the heights of refuse on the fire grates (21) on the basis of the thermal image. A refuse height control unit controls the speed of refuse supplied by a refuse supplying unit (4), the speed of refuse conveyed by a drying fire grate (23), and the speed of refuse conveyed by a combustion fire grate (24), separately, on the basis of the refuse height information such that the distribution of the heights of refuse in the conveyance direction approximates an ideal distribution in which the heights of refuse gradually become lower toward the downstream side in the conveyance direction. Accordingly, the distribution of the heights of refuse in a refuse conveyance path can be stabilized.
