Evaluation and optimization of the system energy of the sintering process in tangsteel

Based on the measuring results of the balance of input and output energy in sintering system in tangsteel, as well as compared to the domestic advanced operation , the concrete methods to improve the efficiency of energy utilization were implemented .For example, it contains to decrease the air leakage of sintering system, to improve the ignition system, and etc.Hence, the actual effects, as the energy consumption of the sintering process decreased and the efficiency of energy utilization increased 6.79%, were realized.It is included that the total output volume of heat decreased 85.49MJ/t, the weight of air leakage in sintering process decreased 36.90%, the waste flue gas weight in sintering system decreased 28.20%, the revert sintering fine ore decreased 21.45 kg/t, and the solid fuel consumption decreased 0.52 kg/t.
