A mathematical model of heat efficiency in the course of heat preservation is established and analyzed based on principle of energy. The results show that the larger the air surplus coefficient, the more the heat loss caused by flue gas and the lower the heat efficiency. On the whole, heat efficiency of anode furnace is on the low level, and the prospect of utilization of waste heat is extensive.

A mathematical model of heat loss of high temperature smoke vented from rotary anode furnace in copper refining based on warm-up burning air was established based on principle of energy balance. The value of heat loss of high temperature smoke vented from it about oxidation phase of rotary anode furnace in copper refining were calculated by using the model. The results showed that when the amouts of oxygen of high oxygen burning air were above about 31 persent reducing trend of heat loss of high temperature smoke vented from it about oxidation phase of rotary anode furnace in copper refining was quite obvious its saving energy was remarkable with the increase of temperature of warm-up burning air. In addition, Some reasonable advices were given and they would be beneficial for more saving energy enhance of oxidation phase of rotary anode furnace in copper refining.

Based on the computational model developed by the authors, the computer simulation on the rational enhancement of flash smelting system is carried out Some important factors affecting the limit productivity such as the matte grade, the oxygen concentration, the ratio of Fe/SiO 2 in the slag, and the copper grade of concentrate are also discussed
