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 that workers adjust the amount of natural gas and combustion-supporting air through experience and judgment. This operation is not conducive to sufficient mixing of combustion-supporting air and natural gas, resulting in waste of natural gas or combustion-supporting air. excess

Embodiment Construction

[0009] Such as figure 1 The specific embodiment of the premixed pressure regulating secondary gas burner and method of the present invention is shown, which is characterized in that a gas pipe 5 is provided, the gas pipe 5 is fixedly linked with the mixing pipe 6, and the mixing pipe 6 is set outside the gas pipe 5 , the mixing pipe 6 is provided with a secondary air outlet 3, the secondary air outlet 3 is provided with a pressure gauge interface 4, the mixing pipe 6 is fixedly linked with the air inlet pipe 1, the air inlet pipe 1 is set outside the mixing pipe 6, and the air inlet pipe 1 Main air outlet 2 is arranged on it.

[0010] In the present invention, the accurate dosage of natural gas and combustion-supporting air is judged by observing the change of the pressure gauge, so that the natural gas and combustion-supporting air are fully mixed in the mixing tube. Reasonable gas volume Mixing gas can reduce gas consumption.

Abstract

The invention relates to a premixing type pressure-adjusting secondary fuel gas nozzle and a method. The remixing type pressure-adjusting secondary fuel gas nozzle is provided with a fuel gas pipe (5) which is fixedly connected with a mixing pipe (6). The mixing pipe (6) sleeves the fuel gas pipe (5). A secondary air port (3) is formed in the mixing pipe (6). A pressure gauge interface (4) is disposed on the secondary air port (3). The mixing pipe (6) is fixedly connected with an air inlet pipe (1). The air inlet pipe (1) sleeves the air inlet pipe (1) and is provided with a main air port (2).

Description

Technical field: [0001] The invention specifically relates to a premixed pressure-regulated secondary 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 current domestic combustion device used in the sintering process of refractory materials is that workers adjust the amount of natural gas and combustion-supporting air through experience and judgment. This operation is not conducive to sufficient mixing of combustion-supporting air and natural gas, resulting in waste of natural gas or combustion-supporting air. excess. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a premixed pressure-regulated secondary gas burner and method that can fully mix combustion-supporting air and natural gas, make reasonable use of combustion-supportin...
