Fremgangsmåde til regulering af en gasbrænder, navnlig ved varmeinstallationer med blæser

摘要

Process for controlling a gas burner (1), especially with a fan (2), uses an electronic control device (3). At initial start-up with a first ignition attempt the control device produces a basic set-up for the signal for the quantity of combustion gas and the quantity of air, which corresponds under probable conditions to a lean mixture. Provided that no flame is observed at the next ignition attempt the combustion gas/air mixture is enriched until a flame is observed. Preferred Features: If a flame is observed at the earliest at the third ignition attempt, the combustion gas feed is immediately interrupted and the procedure is re-started with the basic set-up.
