Combustion system of magnesium reducing furnace

Abstract

The invention discloses a combustion system of a magnesium reducing furnace. The combustion system comprises a hearth, a gas input module, an air input module, a waste gas discharge module, a first temperature controller, a second temperature controller and a pressure transducer, wherein heat accumulation type nozzles are arranged on two sides of the hearth; fire spraying openings of the heat accumulation type nozzles face the inside of the hearth; igniters are arranged on the heat accumulation type nozzles; the gas input module and the air input module respectively convey gas and air to the heat accumulation type nozzle on one side of the hearth and the igniter of the heat accumulation type nozzle; the gas and the air pass through the heat accumulation type nozzle on one side of the hearth and the igniter of the heat accumulation type nozzle and are combusted in the hearth to produce waste gas; the waste gas is discharged out of the hearth through the heat accumulation type nozzle on the other side of the hearth and is finally discharged out of the combustion system of the magnesium reducing furnace through the waste gas discharge module; and the heat accumulation type nozzles on the two sides of the hearth execute working procedures of combusting the gas and discharging the waste gas in turn. The combustion system of the magnesium reducing furnace is high in heat efficiency; and the waste of fuel is reduced; and the production cost can be reduced.

Description

technical field [0001] The invention relates to a combustion system, in particular to a combustion system for a magnesium reduction furnace. Background technique [0002] The reduction and smelting of magnesium using a combustion system is a conventional method, but the reduction and smelting of magnesium usually requires a relatively high temperature, so a large amount of fuel must be burned. However, the existing combustion system of the magnesium reduction furnace consumes a lot of energy and has low thermal efficiency, resulting in A large amount of fuel is wasted, which keeps production costs high. Contents of the invention [0003] The purpose of the present invention is to provide a magnesium reduction furnace combustion system, which has high thermal efficiency, reduces waste of fuel, and can reduce production cost. [0004] The combustion system of the above-mentioned magnesium reduction furnace includes a furnace, a gas input module, an air input module, an exha...
