Controlling oil force draught burner - using blower motor oil pump, fuel valve, mixer and ignition unit with air throughput reduced during ignition

摘要

The air speeds in the mixture forming and ignition section of the mixing system are reduced, compared with the speed relationships with rated throughput, during the ignition operation. The air throughput is already reduced during the preventilation time, and up to the ignition operation. The control has a circuit breaker for interrupting the voltage supply for the blower motor (1) and/or oil pump motor designed as an electric motor. The unit for breaking the circuit is designed as a relay pref. as a time relay with a clearing function. The fuel valve (7) is designed as a magnetic valve with a closing switch provided for the voltage supply. The closing switch is designed as a relay, pref. as a time relay (3) with switch-on delay. USE/ADVANTAGE - Oil burner with automatic oil firing. Reduced air throughput during ignition leads to exclusion of ignition difficulties and pressure surges in combustion chamber are prevented. Immediately or shortly after ignition throughput is brought up to rated throughput.
