The method according to the invention for stabilizing an operating behavior of a power-modulating, air ratio-controlled gas blower burner, compensates for disturbances accompanying changed flow resistance in a combustion air path, burnable gas-air mixed path, heating gas path and/or waste gas path by adjusting the power modulation range. In selected operating states of the gas blower burner and in deviation from normal control operation, the burnable gas-air mixture is temporarily and briefly enriched with burnable gas and the actual flame ionization signal is observed. When a flame ionization stroke observed during enriching is smaller than a first tolerance amount, a lower permissible blower rotational speed is increased. Thereafter, the burner control returns to the normal control operation. |
