AI Technical Summary

Problems solved by technology

Since the direction of gas (coal gas or natural gas) entering the furnace is straight-line operation, and the residence time in the furnace is relatively short, there are always phenomena of unsatisfactory mixing and convection of gas (coal gas or natural gas) and incomplete combustion of gas.

Abstract

This invention declares a telescopic gas lance adaptable for combustion furnace, which has the following structures: inlet pipe of coal gas or natural gas and nozzle of coal gas or natural gas inserted into the air bushing and the air spout pipe, the jet orifices around the outer surface of the end of the coal gas or natural gas nozzle. Two rows of jet orifices are arranged in two rows. The blind plate is melded at the end of the nozzle. The structure of this invention makes the ejective coal gas or natural gas move in a circle and form vortex with air, which elongates its existing time in the furnace to enhance the combustion efficiency and eliminate pollution.

Description

technical field [0001] The invention relates to a casing type gas spray gun for a combustible gas combustion furnace. Background technique [0002] At present, domestic casing type gas spray guns (nozzles or nozzles) that are used for combustible gas combustion furnaces are all gas (coal gas or natural gas) direct injection types when they enter combustion furnaces, incinerators, and other furnaces. Since the gas (coal gas or natural gas) enters the furnace in a straight-line operation, the residence time in the furnace is relatively short, so the mixing and convection conditions of the gas (coal gas or natural gas) are not ideal, and the gas combustion is not complete. Because the quality of gas mixing and convection is directly related to whether the gas combustion is complete, the environmental pollution caused by incomplete gas combustion and the excessive consumption of gas have been bothering people for a long time, becoming a headache.
