Abstract

The invention discloses a gas burner capable of enhancing ultraviolet light signal strength. The technical problems that due to an existing gas burner structure, the distance between a flame detectionprobe and a flame is too large, the ultraviolet light strength is too weak, and an ultraviolet light flame detector is not stable in work are solved. According to the technical scheme, the gas burnercomprises a burner shell (1), a gas channel (2) and an ultraviolet flame detection cooling air channel (3) and an ultraviolet flame detection probe (4). The ultraviolet flame detection cooling air channel (3) extends into the gas channel (2), a through hole communicating with the gas channel (2) is formed in the tail end of the ultraviolet flame detection cooling air channel (3), ultraviolet flame detection cooling air is led into the tail end of the ultraviolet flame detection cooling air channel (3) to be mixed with gas to be combusted, bright flames are formed, and the distance between theultraviolet flame detection probe (4) and the flame can be shortened.

Description

technical field [0001] The invention relates to a gas burner with enhanced ultraviolet signal intensity. Background technique [0002] With the increase of energy costs, in order to reduce energy consumption and save production costs, regenerative burners are becoming more and more popular in the aluminum melting furnace industry, and diffusion regenerative burners have low burning loss, uniform furnace temperature, and low nitrogen oxides. A series of advantages, such as less emissions, account for an increasing proportion of regenerative burners. [0003] Flame detection is the most important safety detection measure when the regenerative burner is running. There are two general flame detection methods at present, one is an ion needle flame detector, and the other is an ultraviolet flame detector. [0004] The basic principle of ultraviolet flame detection is: the open flame will produce ultraviolet rays, and the ultraviolet flame detector can determine whether there is ...
