Problems solved by technology

One is that there is a certain distance between the two injection ports, and the other is that the two are basically ejected straight along the axis of the pipe, causing the two to not be fully mixed, resulting in insufficient combustion of the gas, reducing the combustion efficiency and wasting waste. gas

Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0028] A burner for a roasting furnace, such as figure 1 As shown, it includes an outer tube 1, an air nozzle and an air outlet. The outer pipe 1 communicates with the compressed air and is made of a section of steel pipe. The middle part of the steel pipe is provided with an air inlet, and the upper part of the steel pipe is an air outlet.

[0029] The jet head as figure 2 , image 3 As shown, the jet head includes a gas inlet pipe 9, a lighter 2, and an air inlet disk 7. The gas inlet pipe 9 is made up of a steel pipe with an inner diameter smaller than the outer pipe 1, and the gas inlet pipe 9 is coaxially arranged with the outer pipe 1. The bottom of gas inlet pipe 9 is fixed with outer pipe 1 by threaded connection. The upper end of the gas inlet pipe 9 is substantially flush with the upper end of the outer pipe 1, and the upper end of the ga...

Abstract

The invention discloses a burner for a roaster. The burner comprises an outer pipe, a gas nozzle and a nozzle head, wherein the nozzle head with a gas inlet pipe is arranged at the center of the tail end of the outer pipe. Ignition nozzle holes are reserved on the side wall of the gas inlet pipe corresponding to the tail end of the outer pipe. An air inlet plate is perpendicularly arranged on the gas inlet pipe of the lower portion of the ignition nozzle holes and provided with air via holes used for allowing air to pass, a plurality of gas branch pipes obliquely communicated with the gas inlet pipe are arranged on the outer circumference of the air inlet plate, the upper ends of the gas branch pipes are provided with oblique nozzles along the radial direction of the air inlet plate and facing or distant from the center of the gas inlet pipe, the oblique nozzles of adjacent gas branch pipes face different directions, and an igniter penetrating the air inlet plate from the lower side and corresponding to one side of the ignition nozzle holes is fixedly arranged on the gas inlet pipe below the air inlet plate. The gas branch pipes are obliquely, tangently and consequently disposed along the same circumference of the gas inlet pipe. The burner for the roaster can effectively accelerate mixing of compressed air and gas, and burning efficiency is improved.

Description

technical field [0001] The invention relates to a burner on a roasting furnace, in particular to a burner on a roasting furnace for roasting isostatic graphite. Background technique [0002] Isostatic graphite is a new type of graphite material developed in the 1960s. It is a high-quality graphite material with high strength, high density, good isotropy, good heat resistance, strong chemical corrosion resistance, and machinability. Excellent and other advantages, widely used in metallurgy, chemistry, electrical, aerospace and atomic energy industries and other fields. [0003] The production of isostatic graphite uses pitch coke or petroleum coke as raw materials. The process is: crushing, grinding, kneading, sheeting, isostatic pressing, roasting, impregnation, and graphitization. The roasting process is to put the isostatically pressed graphite into a roasting furnace and roast it to a certain temperature. The roasting furnace generally uses gaseous fuels, such as natural...
