Abstract：

The principle of regenerative combustion technology was briefly described, through the analysis of unsteady heat transfer characteristics on the periodic heating furnace, the high energy-saving features was expounded when the fuel consumption of regenerative combustion was the biggest in heating period. The successful example of regenerative combustion technology in ordnance industry group forging heating furnace was introduced.Compared with the transformation of the former, the exhaust gas temperature decreases from 600 ℃ to 137 ℃, and the ultimate recovery of flue gas waste heat is realized. The average unit consumption decreases from 423.02 m3·t-1 to 123.18 m3·t-1, operating costs per ton of steel drops from 1650 yuan to 480 yuan, and the gas saving achieves 818600 yuan per year,which show that the energy-saving benefit is remarkable.
