Riello is launching an upgraded version of its RDB kerosene burners with flame-detection ionisation probes.
The probes will be available on Riello’s RDB BG Low NOx blue flame kerosene burner range in the UK and Ireland, replacing the ultra-violet (UV) flame sensors currently used to provide a simpler, longer-lasting safety solution.
Ionisation probes are a simpler means of flame supervision, compared to other methods, with a defined life expectancy of approximately 20,000 hours – double the expected life of a UV flame sensor. Located within the flame itself, ionisation probes detect the charged ions that result from the combustion of a hydrocarbon, allowing a small electrical current to be conducted across the flame when applied. If no such current is detected, the burner is forced into a safety shutdown.
Ionisation probes are a proven means of flame detection installed in a vast array of combustion equipment and will soon be available for the RDB BG low NOx kerosene burner range, the company says.
