  • THROTTLE ARRANGEMENT, HEATING UNIT WITH THE THROTTLE ARRANGEMENT, METHOD FOR REGULATING A HEATING UNIT WITH THE THROTTLE ARRANGEMENT, AND ORIFICE MEASURING PATH WITH THE THROTTLE ARRANGEMENT
    Publication number: 20240044487
    Abstract: A throttle arrangement comprising at least one first throttle element and at least one second throttle element, wherein the first throttle element and the second throttle element are connected in series, wherein the first throttle element has a first pressure loss coefficient which correlates positively with a volume flow passing through the throttle arrangement, and the second throttle element has a second pressure loss coefficient which correlates negatively with the volume flow passing through the throttle arrangement.

  • Method and heating unit for flame monitoring during gas combustion
    Patent number: 11821627
    Abstract: A method of monitoring a flame during gas combustion in a combustion chamber (10). A heating unit (1) has an evaluation unit, an extraction line (11) and a sensor (12). The sensor (12) is arranged in the extraction line (11) 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 (12) 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 (11) and thereby determines whether the flame is burning or extinguished.
