Quasi-high speed gas burner for industrial stove

Abstract

The invention relates to a gas burner, in particular to a quasi-high speed gas burner for an industrial stove. The quasi-high speed gas burner comprises a shell, wherein a gas channel and a burning-supporting air channel are arranged in the shell; a mixer is arranged at the tai ends of the gas channel and the burning-supporting air channel; the mixer comprises a first mixing piece plugged at the tail end of the gas channel and a second mixing piece plugged at the tail end of the burning-supporting air channel; a plurality of gas outlets are arranged on the first mixing piece, and a plurality of burning-supporting air outlets are arranged on the second mixing piece; and the gas outlets are arranged in a inclining way, and an included angle between each gas outlet and the vertical direction is 20-40 degrees; the burning-supporting air outlets are arranged in an inclining way, and an included angle between each burning-supporting air outlet and the vertical direction is 20-40 degrees; in addition, the flowing direction of the gas or the burning-supporting air is intersected with the gas outlet direction and the burning-supporting air outlet direction, so that the burning-supporting air and the gas which are subjected to collision synthesis have higher speed, non-rotation flame, high rigidity and higher flame length, so that inside and outlet temperature difference on the cross section of the stove is larger.

Description

technical field [0001] The invention relates to a gas burner, in particular to a quasi-high-speed gas burner for industrial furnaces. Background technique [0002] Burner is a common name for the combustion device used on industrial fuel furnaces, which can be understood as the abbreviation of "fire nozzle". Usually refers to the body part of the combustion device, with fuel inlet, air inlet and injection holes, which play the role of distributing fuel and combustion-supporting air and ejecting them in a certain way for combustion. [0003] The gas burner that industrial kiln is used in the prior art, as the natural gas burner that is used for ceramic tunnel kiln, refer to figure 1 , including the mixer 100' at the end of the burner, the mixer 100' is provided with several 45° inclined gas outlets 10', several horizontal gas outlets 20', several vertical straight combustion air outlets 30' and several rotating Combustion-supporting air outlet 40', in the figure a' indicate...

AI Technical Summary

Problems solved by technology

To avoid the large temperature difference between the inside and outside of the kiln section, high-speed burners must be used, and high-speed burners must be equipped with electronic igniters, fire sleeves and other devices. The structure is complex, bulky, and expensive, and the price is higher than that of ordinary burners. 10-30 times that of ceramic tunnel kiln, and the number of burners required by ceramic tunnel kiln is relatively large. Generally, a tunnel kiln needs 30-250 burners, so high-speed burners are difficult to use in tunnel kilns.
