The device solves correction of the combustion ratio gas - air, especially in industrial gas furnaces with a larger number of zones and one central pre-heating recuperator of combustion air. The membrane regulator (3) is controlled by means of the heater (1), which is connected with the pulse pipeline (2), and it is integrated into the by-pass pipeline (12) of combustion air and it also regulates the flow of combustion air, which helps achieve the required combustion ratio. Correction of the combustion ratio in other zones of the furnace is carried out by means of the branch pipe (4) of the pulse pipeline (2) in the identical manner.<IMAGE> |
