Method and device for monitoring burners

摘要

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?). The burner ( 15 ) is switched off and locked when the flow/boiler temperature (T?VL?) reaches or exceeds the predeterminable second maximum flow/boiler temperature (T?VLmax2?) and additionally when an error signal (F) is produced by the temperature controller ( 5 ). The error signal (F) is produced when the burner ( 15 ) has not been switched off correctly by the temperature controller ( 5 ) when the first maximum flow/boiler temperature (T?VLmax1?) has been achieved.
