| Abstract: | The air-gas double preheater is applied to pushing type reheating furnace at No. 1 bar rolling plant of Jinan iron and steel group,the heating capability is increased notably,gas consumption per ton of steel is decreased. The average temperature of preheating air is increased from 55 C to 478 C. The thermal recovery ratio is inereased from 2. 3 % to 41. 9 %. The average gas consumption per ton of steel in first half of the year, 1998 is decreased by 31. 2Nm3/t than that in 1997. |
