The invention relates to a method for controlling a combustion or gasification device (VB) for small-sized solid fuels (BS) with a spreader feeder (WB). The device (VB) has at least one combustion chamber (BK) and a grate (R) with at least two grate zones, in particular a combustion or gasification zone and a burnout zone, which are arranged in the longitudinal direction of the grate (R). A flame edge (GK) is formed in one of the grate zones, in particular in the burnout zone. In the method according to the invention, an actual position of the flame edge (GK) is monitored (1) using at least one optical camera (K). If the actual position of the flame edge (GK) deviates from a target position, the supply (LV1, LV2) of air, in particular a primary air quantity (PL1, PL2) and/or a primary recirculation quantity (RL1, RL2), into the combustion chamber (BK) is modified (2, 3) in a controlled manner. The method is advantageous in that an air quantity required for a complete burnout of ash (A) in the combustion chamber (BK) is automatically controlled and optimized. Thus, the combustion or gasification device (VB) can react to changing burnout properties in the event of changing fuel properties in an automatic and simple manner. Fig. 1 |
