  • Method and device for monitoring burners
    Patent number: 7090140
    Abstract: The invention relates to a device and a method for monitoring burners using an automatic heating machine (1) for controlling or regulating the burner (15), and a temperature controller (5). At least the flow/boiler temperature (T?VL?) is detected and is compared with a predeterminable first maximum flow boiler temperature (T?VLmax1?) by means of the temperature controller (5). The burner (15) is switched off when the flow/boiler temperature (T?VL?) reaches or exceeds the predeterminable first maximum flow/boiler temperature (T?VLmax1?), while the flow/boiler temperature (T?VL?) is compared with a predeterminable second maximum flow/boiler temperature (T?VLmax2?) which is higher than the predeterminable first maximum flow/boiler temperature (T?VLmax1?).
