increasing of energy efficiency.
Typical energy efficiency measures for an industry with furnace are:
1. Complete combustion with minimum excess air.
2. Proper heat distribution.
3. Operation at the optimum furnace temperature.
4. reducing heat losses from furnace openings.
5.maintaining correct amount of furnace draft.
6. optimum capacity utilization.
7. Waste heat recovery from the flue gases.
8. Minimum refractory losses.
9. Use of ceramic coatings.
10. Selecting the right refractories.
