Abstract

1. A system for the automatic control of the fuel-air ratio in a heat source, comprising a controller (9) for an automatic control of the exhaust gas temperature by a control of a final control element (23) for controlling the supply of air, characterized in that an actual-value sensor (11) measures the dew point temperature and the exhaust gas temperature and that the controller (9) by means of the final control element (23) increases and decreases the supply of air in response to a drop and rise, respectively of the exhaust gas temperature through the dew point temperature.
