Description

Technical Field

[0001] This utility model relates to the field of combustion equipment technology, specifically an improved burner. Background Technology

[0002] Boiler burners, as core equipment for energy conversion, are widely used in many industries such as power, chemical, and metallurgy. Their operational stability directly affects the thermal efficiency and safe production of boilers. The nozzles of traditional boiler burners, as key components for fuel injection and combustion reaction, are in complex working conditions of high temperature and high pressure for a long time, and must be continuously subjected to the direct impact of combustion flames.

[0003] Because traditional nozzles often use a single material or conventional structural design, they are prone to warping and deformation under long-term high temperatures. Nozzle deformation not only disrupts the uniformity of fuel injection, resulting in incomplete combustion and increased energy consumption, but also changes the fit clearance between the nozzle and the flow channel. This causes dust, coke, and other impurities generated during combustion to accumulate on the inner wall of the flow channel and around the nozzle, adversely affecting overall operation and increasing the frequency and cost of equipment maintenance. Utility Model Content

[0004] The purpose of this invention is to provide an improved burner that can form an effective reinforcing structure at the nozzle, reducing the probability of deformation at the nozzle and reducing the frequency and cost of equipment maintenance.

[0008] As a preferred embodiment, the number of the first socket, the second socket, and the stainless steel support rod are all ten.

[0009] As a preferred embodiment, a reinforcing plate is fixedly connected between the left side of the annular seat and the outer surface of the nozzle.

[0010] As a preferred embodiment, a metal washer is fixedly installed around the right side of the burner body, and a mounting plate is fixedly connected to the right end of the burner body.

[0011] As a preferred embodiment, the inner cavity of the nozzle is coated with a silicon carbide ceramic coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, through the combination of annular reinforcing frame, reinforcing protrusions, and reinforcing ribs, can form multiple reinforced supports at the nozzle end, significantly enhancing the structural strength and deformation resistance of the nozzle end.
