Abstract��
This paper discussed the technical characteristic of sulphur hexafluoride production,the characteristics of heat resource and application situation were analyzed.By using the heat releasing from electrobath and chemical reaction with appropriate reconstruction,heat is recovered and the fuel boiler can be replaced.The retrofit can result in saving fuel 0.4 t/t,water 60 t/t,reducing heat output 10 MJ/ t.It is benefit for economics and environmental protection.
