FIELD: machine building.SUBSTANCE: invention relates to a method for controlling combustion or gasification device (VB) for small-sized solid fuels (BS) with spreader feeder (WB). Device (VB) has combustion chamber (BK) and grate (R) with two grate zones. Flame edge (GK) is formed in one of the grate zones. Actual position of flame edge (GK) is monitored using optical camera (K). If the actual position of the flame edge (GK) deviates from a target position, the supply (LV1, LV2) of a primary air quantity (PL1, PL2) and/or a primary recirculation quantity (RL1, RL2), into the combustion chamber (BK) is modified in a controlled manner. Analysis of the snapshots and thus an analysis of the actual position of glowing fire edge (GK) is performed by means of colour evaluation using virtual sensors that assume at least three states, especially a positive state, a warning state and an error state depending on the determined actual colour values, the virtual sensors are arranged in rows.EFFECT: high efficiency and simple method of automation of burnout of the ash.3 cl, 1 dwg |
