在钢铁企业中,烧结工序能耗占总能耗的10～12%,仅次于炼铁而居第二位,我国烧结生产的能耗指标和先进国家相比差距较大。大体上而言,每吨烧结矿的平均能耗要高出20kg标煤。国内先进企业烧结工序的燃气单耗一般为0.065GJ/t,而先进国家的指标则已达0.025-0.03GJ/t。烧结生产放散到大气中的气体显热为烧结总热耗的50%,其中冷却机废气带走的热量约占烧结总热量的30%左右,把这些气体的余热 In the iron and steel enterprises, the sintering process energy consumption accounts for 10 ~ 12% of the total energy consumption, second only to ironmaking and ranks second. The energy consumption index of China’s sintering production has a big gap compared with the advanced countries. In general, the average energy consumption per ton of sinter is 20 kg higher than standard coal. The unit consumption of gas in the sintering process of advanced enterprises in China is generally 0.065GJ / t, while that of advanced countries has reached 0.025-0.03GJ / t. The sensible heat of gas released into the atmosphere by sintering is 50% of the total heat loss of the sintering, in which the heat taken off by the cooler exhaust gas accounts for about 30% of the total heat of sintering, and the waste heat of these gases
