Abstract

The invention relates to the field of heat treatment, particularly to a low carbon and energy-saving gas heat treatment tunnel kiln, and aims to solve problems of low fuel combustion rate, low combustion temperature and the like existing in the gas heat treatment tunnel kilns in the prior art. The gas heat treatment tunnel kiln is provided with a burner and a rich oxygen generator, wherein the burner is connected with a gas transmitting device through a gas pipeline, the burner is connected with the rich oxygen generator and a draught fan through an air supply pipeline, and the burner is of a vortex type or a whirlwind type. Due to the adoption of the vortex type burner or the whirlwind type burner, emission capacity of carbon monoxide is 20 times less than the emission capacity of carbon monoxide of ordinary burners, and gases can be burned sufficiently. Emission standard of ordinary burners is less than 0.20 % and the emission standard of the vortex type burners is less than 0.011%. Due to the fact that the rich oxygen generator is additionally arranged on an air supply system, gas supply quality can be saved about 10%.

Description

technical field [0001] The invention relates to the field of heat treatment, in particular to a low-carbon energy-saving gas heat treatment tunnel furnace. Background technique [0002] The use of burners in gas-fired heat treatment tunnel furnaces is an indispensable equipment. Especially in recent years, with the development of science and technology and the requirements of environmental protection, people's demand for burners that use gas, liquid, and gas-liquid mixtures as fuel is increasing. more and more widely. However, with the energy crisis and the increase in fuel prices, the society must be required to provide more efficient, energy-saving and environmentally friendly burners. [0003] At present, the burners of traditional gas-fired heat treatment tunnel furnaces often have unburned molecules discharged with the tail gas, resulting in incomplete combustion, low fuel combustion rate, and low combustion temperature, resulting in the escape of combustion molecules....
