Abstract
A magnesium reduction furnace combustion system comprises a furnace chamber, a fuel gas delivery module, an air delivery module, a waste gas discharging module, a first temperature controller, a second temperature controller and a pressure transmitter. Regenerative burners are arranged at two sides of the furnace chamber. A fire spraying opening of each regenerative burner is towards the inner side of the furnace chamber. Each regenerative burner is provided with an igniter. The fuel gas delivery module and the air delivery module respectively deliver fuel gas and air to the regenerative burner and the igniter at one side of the furnace chamber. The fuel gas and the air are burned in the furnace chamber through the regenerative burner and the igniter at one side of the furnace chamber and waste gas is generated. The waste gas is discharged out of the furnace chamber through the regenerative burner and the igniter at the other side of the furnace chamber and is discharged out of the magnesium reduction furnace combustion system through the waste gas discharging module. The regenerative burners at two sides of the furnace chamber conduct the processes of burning the fuel gas and discharging the waste gas in turn. The magnesium reduction furnace combustion system is high in heat efficiency and capable of reducing waste of fuel and reducing production cost.
