Method and device for heating up a furnace zone containing contaminated waste gases with residual oxygen content applies hot gases generated by fuel combustion to the waste gases

摘要

A burner has a casing (1) that connects to a wall (2) in an appropriate furnace zone and houses a furnace port-end (3) operating as a gas-air port mixer. This is connected to a gas supply pipe (5) via a main gas pipe (4). Combustion air reaches the port-end via the casing connected to an air supply pipe (6) fed by a fan. The gas supply pipe has a regulator (8) that depends on the flow pressure in the air supply pipe.
