Description

Technical field: [0001] The invention specifically relates to a hydraulically adjustable premixed gas burner and a method thereof, which belong to the technical field of kiln combustion and are suitable for the combustion application of refractory materials. Background technique: [0002] As far as the inventor knows, the combustion device used in the sintering process of refractory materials in China is diffusion combustion, and the commonly used diffusion combustion is that the gas-supporting gas and the gas are mixed while burning, and there are several disadvantages; It causes excess gas-supporting gas, increases the temperature of the exhaust gas, and increases the heat loss of the kiln. The second is that the gas cannot be fully burned due to poor mixing, resulting in excess fuel, thus wasting fuel. On the other hand, the combustion devices used in the sintering process of refractory materials are all installed at fixed positions. The burners on the commonly used comb...

Problems solved by technology

[0002] As far as the inventor knows, the current domestic combustion device used in the sintering process of refractory materials is diffusion combustion, and the commonly used diffusion combustion has several disadvantages in the combustion while the auxiliary gas and gas are mixed; Cause excess combustion gas, increase the temperature of the exhaust gas and increase the heat loss of the kiln

Second, due to poor mixing, the gas cannot be fully combusted, resulting in excess fuel, thus wasting fuel

The working method of the burner on the existing design combustion device is to sinter by the external flame under the condition of heat radiation, and at the same time, the highest temperature part is not on the sintered object on the kiln wall, and part of the heat energy is transferred by the inner kiln wall and the sintered object through radiation. It is not directly sintered by flame, so in the actual operation, the fire outlet of the kiln wall is particularly deformed due to sintering. In addition, the temperature inside the kiln wall is higher than the temperature of the sintered object, which is a waste of fuel
