Claims6
A gas burner with a flue conduit provided with means for adjustably supplying a combustible gas, and an excess of combustion air comprising a by-pass conduit for a portion of the combustion air which is not used for the formation of a combustible gas/air/mixture, which by-pass conduit is connected with the flue conduit at a point spaced from the burner, the gas burner being further provided with a built-in gas control valve and with a built-in air control valve, which are coupled so as to be moveable in synchronism, the air control vale provided with means for adjustably dividing the combustion air into a first amount, which is used for formation of the gas/air/mixture, and a second amount for flow through the by-pass conduit, such that when the first amount increases the second amount decreases accordingly and vice versa.
A gas burner comprising a housing, a gas nozzle, a gas supply pipe provided with an adjusting valve and connected with the gas nozzle, an air supply pipe provided with an adjusting valve and connected with the gas nozzle, a mixing cup positioned around the gas nozzle and having passages, as well as a combustion chamber connected to the mixing cup, said gas burner being connected to a flue conduit, a by-pass conduit formed between the inner wall of the flue conduit and the outer wall of a part of the housing, said by-pass conduit connected by one or more passages with the air supply pipe, the air control valve being comprised of a slide valve provided with valve means cooperating with said passages and a valve means cooperating with the passages in the mixing cup, the gas control valve being provided with a valve rod and a valve body cooperating with an annular seat in the gas nozzle, a carrier secured on the valve rod which is connected with the slide valve by one or more rods and a servomotor means to drive the valve rod.
