Sequential control device for Brown gas combustion application

Abstract

The invention provides a sequential control device for Brown gas combustion application. The sequential control device for Brown gas combustion application comprises a fuel pipe, a first pressure adjusting valve, an air-fuel ratio valve and a first electronic stop valve, wherein the first pressure adjusting valve, the air-fuel ratio valve and the first electronic stop valve are installed on the fuel pipe. The sequential control device for Brown gas combustion further comprises an air pipe and a variable-frequency draught fan installed on the air pipe. The sensing end of the air-fuel ratio valve is connected to the air pipe and adjusts the fuel output amount of the fuel pipe according to the output amount of the air pipe. The air pipe and the fuel pipe are connected to a combustion gun. Thecombustion gun heats a hearth. The sequential control device for Brown gas combustion application is characterized by further comprising a Brown gas pipe, a second pressure adjusting valve and a second electronic stop valve, wherein the Brown gas pipe is connected to the fuel pipe, the second pressure adjusting valve and the second electronic stop valve are installed on the Brown gas pipe, and the first electronic stop valve and the second electronic stop valve are electrically connected to a sequential controller. The sequential control device for Brown gas combustion application sequentially controls output of the fuel and the Brown gas, and when the mixture of the fuel and the Brown gas is combusted, hydrogen detonation and backfire problems of the Brown gas are prevented, and the detonation problem is relieved.

Description

technical field [0001] The invention relates to the technical field of fuel combustion equipment, in particular to a time sequence control device for Brown gas applied combustion. Background technique [0002] The spray gun currently used for fuel combustion is equipped with a spray gun head near the nozzle. In order to make the fuel fully contact with the air when the spray gun tube burns, a number of vent holes are provided on the side and end surface of the spray gun head so that when the fuel comes out of the spray gun It is divergent, and the structure of this spray gun head is very effective for burning ordinary fuel, which can reduce black smoke, save fuel, and will not cause other problems, but for Brown gas (hydrogen-oxygen mixed gas), this structure will cause Severe whistling phenomenon, and when Brown gas is ignited or burned alone, because it can burn without the help of external oxygen, there is a safety problem of tempering.
