Burner with enhanced fire transfer function and heating furnace using the same

Abstract

The invention discloses a burner with enhanced fire transfer function and a heating furnace using the same, wherein the burner with enhanced fire transfer function comprises: a first air plate is installed at one end away from the air inlet of the burner assembly, so The second air plate is installed at one end close to the air inlet of the burner assembly, and the first air plate is provided with a fire transfer structure, so that the flames of the plurality of fire transfer holes on the burner assembly are connected in series to strengthen the fire transfer function. The burner with the enhanced fire transfer function of the present invention not only fixes the relative positions of the plurality of single pieces of the fire row in the burner assembly, but also ensures the overall strength of the burner assembly by means of the first air plate provided with the fire transfer structure. The gaps between the single pieces of the multiple fire bars are ensured to ensure that the flame can spread quickly, so as to achieve the purpose of improving the success rate of fire transfer. At the same time, compared with the existing fire bars, the production and assembly changes are small, the structure is reliable, the stability is good, and there is no cost. Rising, suitable for mass promotion.

Description

technical field [0001] The invention belongs to the technical field of gas heating furnaces, and particularly relates to a burner with enhanced fire transmission function and a heating furnace using the same. Background technique [0002] Existing heating furnace burners are mainly divided into atmospheric burners and fully premixed burners, of which atmospheric burners are the most widely used. For the mixing section of a single piece, the throat diameter is generally not less than 17mm due to the need to ensure the mixing effect of gas and air, so there is at least one throat diameter distance between the single pieces of the fire row. The larger the distance between the single pieces of the fire row, the slower the fire transmission speed and the lower the success rate, which will lead to a longer ignition heating time and affect the comfort of hot water. [0003] At present, the industry has the following solutions for this problem: 1) Increase the secondary air plate t...

AI Technical Summary

Problems solved by technology

The larger the distance between the single pieces of the fire row, the slower the fire transmission speed and the lower the success rate. If it is light, it will lead to longer ignition and heating time, which will affect the comfort of hot water. If it is serious, it will cause the whole machine to fail to ignite and cannot be used.

[0003] At present, the industry has the following solutions to this problem: 1) Increase the secondary air plate to reduce the secondary air velocity at the fire transmission hole of the fire row, thereby improving the success rate of fire transmission. However, this kind of solution needs to increase the secondary air flow. 2) Using a variable speed fan to reduce the fan speed during ignition, thereby improving the success rate of fire transmission, but this method is only applicable to products with speed regulation function; 3) Using a composite unit The single piece of the burner is divided into a fire hole piece and a single piece main body. The single piece main body includes a projection section, a mixing section and a fire transmission structure. The fire hole piece is embedded on the single piece main body and is fixed by spot welding, but , the processing of the fire row is complicated, the cost is high, and the welding quality of the fire hole sheet is high. If it is used for a long time, the fire hole sheet has the risk of desoldering
