Abstract

The invention belongs to the technical field of aluminum smelting, and particularly relates to a natural gas aluminum smelting furnace. In order to overcome the defect that an existing aluminum smelting furnace is low in energy utilization efficiency, the following technical scheme is adopted: the natural gas aluminum smelting furnace comprises an air preheating system, a gas heating system and a gas heating system, a natural gas supply system; an aluminum material preheating system; an aluminum material supply system; a molten aluminum production system; a hot water heating system; a flue gas emission system; operating the control system; wherein a cold side inlet of the air preheater is connected to the combustion fan, a cold side outlet of the air preheater is connected to the melting burner and the heat preservation burner, a hot side inlet of the air preheater is connected to the aluminum material melting chamber, and a hot side outlet of the air preheater is connected to the aluminum material preheating box and the hot water heater. The natural gas aluminum smelting furnace has the beneficial effects that flue gas waste heat is fully utilized to preheat air, aluminum materials and water, and the energy utilization efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of aluminum smelting, and in particular relates to a natural gas aluminum smelting furnace. Background technique [0002] At present, some non-ferrous metal smelting enterprises use natural gas smelting furnaces with low energy efficiency, and the high-temperature flue gas from the smelting furnaces is directly discharged, resulting in a great waste of energy. [0003] Based on the energy consumption characteristics of non-ferrous metal smelting enterprises, how to effectively improve the energy utilization efficiency of natural gas aluminum smelting furnaces under the premise of ensuring safe and stable smelting aluminum quality and output is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The invention aims at the problem of low energy utilization efficiency existing in existing aluminum smelting furnaces, and provides a natural gas aluminum smelting furnace...
