Industrial gas burner

Abstract

The invention discloses a burner for burning an industrial gas. The structure of the industrial gas burner is as follows: a gas chamber is arranged at the tail end of a gas supply pipe, the gas chamber is separated from an air chamber by a partition plate, a gas distribution pipe bundle is arranged on the partition plate and positioned inside the air chamber, guide vanes are arranged inside the individual gas distribution pipes, holes are formed on the walls of the individual gas distribution pipes and communicated with the air chamber, and the distance from the tail end on the downstream side of the gas distribution pipe bundle to the margin of the tail end of the air chamber ranges from 30 mm to 50 mm, which defines a space that serves as a gas and air mixing and combustion chamber.

Description

technical field [0001] The invention relates to a combustible gas burner for industrial use, more precisely, the invention is a burner for burning industrial gas. The burner consists of an air chamber, a gas chamber, a gas distribution tube bundle placed in the air chamber, a central tube gun with an ignition electrode inside the burner, a combustion head at the front and a mounting flange. technical background [0002] Most of the existing industrial gas burners adopt the blower type premixing structure, emphasizing the full mixing of gas and combustion air. However, there are common problems such as low power, inaccurate ratio of gas and air, limited load adjustment range, poor safety and high requirements for gas performance, especially for large industrial gas burners. At present, there are also some domestic patented technologies related to the research on the above problems, but the way to solve the problem is too single and cannot take into account each other, such a...

AI Technical Summary

Problems solved by technology

Although this technology solves the problem of mixing gas and combustion-supporting air, the structure is too complicated, especially this type of burner has high requirements for gas pressure and cleanliness, and the flame stability is poor when the gas source pressure fluctuates

[0003] Existing types of burners are not suitable for burning industrial gas with low calorific value (such as blast furnace gas), especially not suitable for burning gas containing more solid impurities. The burner also has the disadvantage of being prone to tempering

In addition, due to the low calorific value of industrial gas, all kinds of burners now have the common problem of difficulty in ignition
