Abstract
A method of monitoring a flame during gas combustion in a combustion chamber (). A heating unit () has an evaluation unit, an extraction line () and a sensor (). The sensor () is arranged in the extraction line () to detect thermal substance properties of the gas. Thus, it is determined if it is ambient air (B), a non-combusted fuel-air mixture (C) or particularly the hydrogen-air mixture, or a waste gas (A) generated during combustion. The sensor () transmits a recorded measured value to the evaluation unit. The evaluation unit uses the measured value to determine whether ambient air (B), the non-combusted fuel-air mixture (C), or waste gas (A) is flowing through the extraction line () and thereby determines whether the flame is burning or extinguished.
