Abstract (en)
[origin: EP3845806A1] Provided is a stoker furnace having: a burn-off-point detection device (31) that acquires a detection signal corresponding to the burn-off-point (P) of an object (B) to be incinerated; a first drive device (18a) that drives moving grates of a drying stage (11); a second drive device (18b) that drives moving grates of a combustion stage (12); a third drive device (18c) that drives moving grates of a post-combustion stage (13); and a control device (30), wherein the drying stage (11) is disposed to be inclined such that a downstream side thereof faces downward, the combustion stage (12) and the post-combustion stage (13) are disposed to be inclined such that downstream sides thereof face upward, and the control device controls the second drive device and the third drive device such that when the position of the burn-off-point (P) does not exceed a target burn-off-point, the moving grates of the combustion stage (12) and the moving grates of the post-combustion stage (13) are not changed, and when the position of the burn-off-point (P) is located downstream of the target burn-off-point, the drive speed of the moving grates of the post-combustion stage (13) is slower than the drive speed of the moving grates of the combustion stage (12).
