In the energy composition of industrial furnaces, fuel consumption accounts for 90% of total energy consumption, and electricity consumption accounts for only 7.9. Therefore, it is necessary to focus on the energy of various industrial furnaces to heat fuel (collectively referred to as fuel furnaces).
The excellent design and the correct operation of the fuel furnace have good technical and economic benefits compared with the furnace's thermal performance. Some measures for energy-saving fuel furnaces, such as the improvement of production management and operation methods, the use of light and ultra-light refractory linings, improved sealing performance, improved furnace structure and reasonable layout of combustion devices, these requirements are also applicable to industrial furnaces.
2) The efficiency of electric arc furnace equipment should not be less than 50%, and the efficiency of other heating equipment should not be less than 40%.
3) Electric heating equipment is equipped with voltmeter, ammeter, watt-hour meter, and reactive watt-hour meter above 50kW.
4) Improvement of device structure and process conditions, production concentration, shortening of waiting time and other measures to improve load-bearing capacity and improve thermal efficiency are realized.
5) Do a good job in the recovery of waste heat from industrial furnaces.
