1. Copper ingot jealous flue gas waste heat utilization design and operation of the device 1.1 Characteristics of flue gas Copper ingot furnace is a heavy fuel oil reverberatory furnace, each furnace load 85 tons, with an annual output of 27,000 tons of copper ingots, annual consumption of 2,600 tons of fuel. The flue gas is characterized by: 1.1.1 smoke temperature, flue gas volume fluctuations. The thermal strength of the copper ingot furnace is 40 to 450,000 kcal / m3, the temperature in the furnace is 1500 ° C, the temperature of the exhaust gas is up to ~ 1200 ° C, and the exhaust heat accounts for more than 50% of the heating value of the fuel. Copper ingot furnace cycle
