Single way jet gas reflux type burner

Abstract

The reflux burner with single way gas jet includes gas supply system, fuel supply system and high temperature heating and vaporizing system. The high temperature heating and vaporizing system consists of hollow ring afterheat pre-vaporizer in hearth mouth and radiating vaporizer in hearth. Compared with available technology, the present invention has the advantages of complete vaporizing of liquid heated into high temperature fuel gas, heat and mixing with fuel gas of air in the hearth, no temperature peak of flame, no boundary surface, high temperature and heat efficiency, lower fume temperature and exhaust, and other advantages. Especially, its high temperature radiating main vaporizer in hearth with fuel gas turning board results in long vaporizing time and homogeneous and stable fuel gas heating, and the single way guide jet and single way fuel gas releaser results in stable vaporizing pressure, no reflux, homogeneous fuel release and synchronous control.

Description

technical field [0001] The invention relates to a burner, in particular to a one-way injection gas return flow burner which utilizes high-temperature gas and high-temperature air mixed swirling combustion. Background technique [0002] At present, there are many kinds of burners on the market, the first is liquid atomization burner, the liquid fuel is mixed with air after atomization, and the second is liquid fuel vaporization burner, which is mixed with air after liquid fuel is vaporized Combustion; the third is the fuel burner, the normal temperature gas fuel and the normal temperature air are mixed and burned. The disadvantage of these three burners is that the temperature of the gas and the air is low before starting to burn, and the combustion must be carried out under oxygen-enriched conditions. The amount of oxygen is large, the combustion is unstable, the flame in the furnace has a temperature peak, there is a flame interface, the temperature difference is large, the...

[0002] At present, there are many kinds of burners on the market, the first is liquid atomization burner, the liquid fuel is mixed with air after atomization, and the second is liquid fuel vaporization burner, which is mixed with air after liquid fuel is vaporized Combustion; the third is the fuel burner, the normal temperature gas fuel and the normal temperature air are mixed and burned. The disadvantage of these three burners is that the temperature of the gas and the air is low before starting to burn, and the combustion must be carried out under oxygen-enriched conditions. The amount of oxygen is large, the combustion is unstable, the flame in the furnace has a temperature peak, there is a flame interface, the temperature difference is large, the thermal efficiency is low, the content of CO and NOx is high, the combustion cannot be fully, the environment is polluted and the energy is wasted
