Fuel pre-mixing type multi-spray-gun aluminium homogenizing furnace

Abstract

The invention discloses a fuel pre-mixing type multi-spray-gun aluminium homogenizing furnace. The multi-spray-gun aluminium homogenizing furnace comprises a furnace body, at least five combustion spray guns and a smoke pipeline, wherein a hearth used for heating aluminium materials is disposed in the furnace body; the at least five combustion spray guns are disposed at the same side wall of the furnace body at intervals; the near end of each of the combustion spray guns extends out of the furnace body; the far end of each of the combustion spray guns extends into the hearth; and the smoke pipeline is communicated with the hearth so as to exhaust produced smoke to a chimney. The multi-spray-gun aluminium homogenizing furnace further comprises a premix device used for premixing fuel and air. The near ends of the at least five combustion spray guns are separately communicated with the premix device so as to spray the gas mixture in the premix device from the far ends of the at least five combustion spray guns into the hearth to be combusted. The multi-spray-gun aluminium homogenizing furnace is easily controllable, energy-saving and environmental friendly.

Description

technical field [0001] The invention relates to a homogeneous furnace, in particular to a multi-spray gun aluminum homogeneous furnace. Background technique [0002] In the face of increasingly severe environmental problems and energy crises, the whole world is vigorously advocating energy conservation and emission reduction, especially for industrial kiln related industries with serious energy consumption and pollution. Factors that personnel must consider when designing such equipment. [0003] Taking the homogenizing furnace as an example, the existing homogenizing furnace generally uses natural gas as fuel. Such as figure 1 shown. The natural gas fuel is directly combusted in the furnace body 1 through a number of combustion lances 3 through the fuel delivery pipe 2, and the air required for combustion is input into the furnace by the fan through the input air pipe 8 and mixed with natural gas to provide sufficient oxygen for combustion. The heat after combustion hea...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the existing homogeneous furnace has the following defects: (1) The fuel delivery pipe is directly connected to several combustion lances to provide fuel for the combustion lances. Due to the large number of combustion lances and the difficulty in controlling the fuel delivery, it is difficult to control the combustion firepower, making it difficult to It is difficult to achieve the best combustion ratio between fuel and air, the combustion is not sufficient, and the emission pollution is large; (2) The flue gas is directly discharged, and its temperature can reach above 450 degrees, resulting in huge heat dissipation loss. As fuel prices are getting higher and higher environment, seriously increasing the burden on users

The continuous circulation heat treatment furnace has a unique structure and is not suitable for retrofitting the existing homogeneous furnace
