Purpose
The Flame Safeguard monitors the burner operation of a furnace.
With multiburner installations, the burner flame can be selectively acquired and transmitted, i.e independent of the operating condition of the other burners directed to the same combustion chamber. flames, i.e. independently of the operating state of the adjacent burners in the same combustion chamber. In case of flame rupture a safe switching state is produced for the non-existing flame resulting in a cut-off of fuel supply to the defective burner.
This device is mainly utilized in large power stations, heating stations and chemical
plants but also used for monitoring furnaces fired with
- oil
- gas
- pulverized coal
- wood dust and chips
- chemical and other waste products
The Flame Safeguard F 250/FFS 05 ... is designed to suit the high-duty operating conditions
prevailing in such places. It provides for a high safety, availability and ease of
servicing through
- a digital signal processing
- a dynamic self-checking and
- an appropriate number of checking and operational controls.
A potential-free, safe change-over contact is available at the outlet of the flame safeguard.
The two-channel design of the flame safeguard with dynamic electronic self-check and safety cut-out due to fault and the contacts connected in series by the two output relay meet, in addition to component testing, additional requirements on the design of safety devices according to DIN VDE 0116 and TRD 604 for a 72-hours-operation.
