Abstract

The invention discloses an ejector combustor of a carbon roasting furnace for aluminum. The ejector type combustor includes a nozzle. The side wall of the nozzle is hermetically connected with a mixing body through a second sealing gasket. The side wall of the lower end of the mixing body is hermetically connected with a connector through a first sealing gasket. The side wall, located in the mixing body, of the nozzle is provided with an ejector nozzle. The side wall of the mixing body is provided with a diffusion pipe. The diffusion pipe is connected with the side wall of the mixing body. Theportion, away from the nozzle, of the side wall of the mixing body is hermetically connected with an ejector body matched with the diffusion pipe. The side wall of the upper end of the ejector body is hermetically connected with an air tap, and the end, far away from the ejector body, of the air tap is hermetically connected with a cooling pipe. According to the ejector combustor of the carbon roasting furnace for aluminum, natural gas can be fully mixed with air, the optimal combustion ratio is achieved, the combustion efficiency is achieved, energy is saved, gas pressure is increased, a product is uniformly heated, a burner can be rapidly cooled, coking substances and oxides left on a protective sleeve pipe and the head of the burner are blown off, and the unobstructed burner and straight flames are ensured.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to an injection burner for a carbon roasting furnace for aluminum. Background technique [0002] The most complex and important part of the roasting workshop is the control of the roasting process. Through the control of the entire combustion system, the temperature of the flue can be controlled, so that the temperature of the flue can be raised according to the established heating curve, and the pre-baked anode can be indirectly controlled periodically. Roasting. The key link in this control process is the normal combustion of natural gas. In actual production, the temperature of the flue path often fails to meet the specified requirements due to abnormal combustion of natural gas, causing many control problems. A series of problems such as unreasonable location of volatile components, excessive natural gas, excessive discharge of purified tar, and product qualification rate are c...
