Embodiment approach

[0027] figure 1 Shown is an embodiment of the novel burner with arc-shaped body jet device of the present invention, the novel burner with arc-shaped body jet device includes combustion tube 1, nozzle 2, arc-shaped body jet device, air Pipe 5, gas pipe 6, automatic ignition device 9 and controller 12.

[0028] The nozzle 2 is a streamlined cavity structure with an inlet and an outlet, the inlet of the nozzle 2 is fixedly connected to the gas pipe 6, and the outlet of the nozzle 2 extends into the rear end of the combustion pipe 1, so The front end of the combustion tube 1 is a flame outlet; the outlet of the nozzle 2 is an involute opening structure. The nozzle 2 is streamlined, and the method of using the jet to induce air can reduce the loss of kinetic energy, prevent the backflow of gas, realize automatic air distribution, and make full use of the gas; due to the adoption of the air induction method, the combustion-supporting fan is removed, which saves Power consumption ...

Abstract

The invention provides a novel burner with an arc-shaped body jetting device. The burner comprises a combustion tube, a spray nozzle, the arc-shaped body jetting device, an air tube, a gas tube, a gas tube automatic regulating valve, a temperature sensor and a controller. According to the novel burner provided by the invention, the outlet of the spray nozzle is an involute structure which is matched with an arc-shaped diameter regulating valve body of the arc-shaped body jetting device, so that the gas flow is in a streamline form, kinetic energy loss is reduced, and impact force of flames is guaranteed. According to the dosage of the gas and the air, the controller automatically controls the opening size of the automatic regulating valve, so that an air-fuel ratio is reasonably controlled. The novel burner solves the problems that in a current steel ladle roasting process, blast furnace gas with a low calorific value is not easy to ignite under a normal-temperature state, and is easy to extinguish, further solves the problems such as insufficient flame power, great resistance, incomplete gas combustion, and the like, and has the advantages of being reasonable in structure, convenient to use, and the like.

Description

technical field [0001] The invention belongs to the technical field of combustion nozzles, and in particular relates to a novel burner with an arc-shaped body jet device. Background technique [0002] The use of burners in the metallurgical industry is very common, which promotes the rapid development of iron and steel enterprises, and the energy consumption of iron and steel enterprises is also increasing day by day, causing serious pollution to the environment, especially the smog produced is very harmful to human health. Therefore, finding a way to improve fuel combustion efficiency and reduce emissions of polluting gases is a major event that benefits the country and the people. [0003] Chinese patent CN2640661 disclosed a regenerative ladle roaster on 2004.09.15. This kind of ladle roaster needs to rely on the combustion-supporting fan to burn normally. The power of the combustion-supporting fan is large, it is difficult to accurately adjust the ratio of air to fuel, ...
