Fuel premixed multi-lance aluminum material homogeneous furnace

Abstract

The invention discloses a fuel premixed multi-spray gun aluminum material homogeneous furnace, which comprises: a furnace body, the furnace body is provided with a furnace for heating aluminum materials; at least five combustion spray guns are arranged at intervals on the furnace body On the same side wall, the proximal end of each combustion lance extends outside the furnace body, and the far end of each combustion lance extends into the furnace; and the flue gas pipe communicates with the furnace to discharge the generated flue gas to the chimney ; Wherein, the fuel premixed multi-spray gun aluminum material homogeneous furnace further includes a premixing device for premixing fuel and air, and the near ends of at least five combustion spray guns are respectively communicated with the premixing device so that the premixing device The mixed gas is injected from the far ends of at least five combustion lances into the furnace for combustion. The fuel premixed multi-spray gun aluminum material homogeneous furnace of the present invention is easy to control, energy-saving and environment-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
