Combustor for smelting process

Abstract

The invention discloses a combustor for a smelting process. The combustor comprises a combustion furnace end assembly, an air supply device and a combustion improver conveying device, wherein an air inlet of the combustion furnace end assembly is connected with an air outlet of the air supply device; and the outlet of the combustion improver conveying device is arranged between the air inlet of the combustion furnace end assembly and the air outlet of the air supply device. According to the combustor, the air inlet amount, the air inlet force and the air inlet stability can be flexibly adjusted; through the combustion improver conveying device, the gas pressurization of a combustion improver can be adjusted; the air supply device is provided with a spiral and straight-through air inlet structure, so that the air inlet stability and the air inlet amount can be flexibly adjusted; through the the optimal state of a scientific ratio of the air inlet amount, the air inlet stability, the combustion improver and fuel gas as well as the supply of the optimal air inlet pressure, the energy efficiency ratio of the combustor can be good, the relatively high temperature of the combustor can be achieved, the energy efficiency conversion can be improved to the maximum extent under the condition that the fire power is guaranteed, and the energy-saving and environment-friendly effects can be achieved; and the combustor has popularization and application values.

Description

technical field [0001] The invention relates to a smelting process equipment, in particular to a smelting process burner. Background technique [0002] The burner is a general term for devices that make fuel and air spray out and combust in a certain way. Burners are divided into industrial burners, burners, civil burners, and special burners according to types and application fields. It is mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or metal titanium. The function of the burner is to atomize the sample by flame combustion. The atomized test solution enters the burner, and under the action of flame temperature and flame atmosphere, it undergoes drying, melting, evaporation, dissociation and other processes to produce a large number of ground state atoms, as well as some excited state atoms, ions and molecules. A well-designed burner should have high atomization efficiency, low noise, and stable flame performance to e...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, coal is mostly used for smelting combustion, and the temperature for smelting with gas is insufficient. The reason is that the temperature of the burner in the prior art cannot meet the requirements, and the energy consumption required to meet the requirements is high. Therefore, the energy consumption of smelting is high. Low utilization rate and poor energy efficiency ratio, therefore, there is room for improvement
