Embodiment 1
[0021] A method for reducing the concentration of carbon monoxide in the tail gas of Ausmelt furnace, such as figure 1 As shown, the following steps are included, and the following steps are carried out in sequence
[0022] Step 1. Measure the concentration of carbon monoxide in the tail gas of Ausmelt furnace. After the measured value of carbon monoxide concentration is higher than 3000ppm, reduce the coal consumption of the spray gun by 100kg, and reduce the coal consumption of the spray gun by 100kg every minute until the concentration of carbon monoxide in the tail gas is lower than 3000ppm , or the coal consumption of the spray gun is less than 3000kg / h;
[0023] Step 2: Keep the Ausmelt furnace continuously in production, and the surface of the molten pool is 1600mm. For every 100mm increase in the height of the molten pool, the amount of pulverized coal is increased by 50kg, and the temperature of the molten pool is increased to ensure the smooth discharge of Australian...

[0028] A method for reducing the concentration of carbon monoxide in the tail gas of Ausmelt furnace,
[0029] Step 1. Measure the concentration of carbon monoxide in the tail gas of Ausmelt furnace. After the measured value of carbon monoxide concentration is higher than 3000ppm, reduce the coal consumption of the spray gun by 100kg, and reduce the coal consumption of the spray gun by 100kg every minute until the concentration of carbon monoxide in the tail gas is lower than 3000ppm , or the coal consumption of the spray gun is less than 3000kg / h;
[0030] Step 2. Keep the Ausmelt furnace continuously in production, and the surface of the molten pool is 1800mm. For every 100mm increase in the height of the molten pool, the amount of pulverized coal is increased by 50kg. Increase the temperature of the molten pool to ensure the smooth discharge of Australian slag, and the temperature of the molten pool Increase to 1320°C;
[0031] Step 3. Measure the oxygen concentration of t...
