我厂是一个火法炼锌为主的有色金属冶炼厂,每年消耗各种能源折合成标准煤为21万吨,其中进厂的燃料煤和作为炼锌还原剂用的焦煤16万吨,占使用能源总量的74.6%;电能消耗占16.6%,重油、焦炭消耗占8.8%。此外,每年使用的锌、钴精矿中含硫57,300吨,在焙烧工艺中产生热能达26,400吨标煤。全厂综合热效率只有40%,余热资源初步统计有14.7万吨标煤,由此可见,我厂消耗大,余热 Our factory is a non-ferrous metal smelting furnace mainly based on pyroxey, which consumes 210,000 tons of standard coal each year, of which 160,000 tons of fuel coal and 16,000 tons of coking coal are used as smelting reducing agent, accounting for Using 74.6% of the total energy; electricity consumption accounted for 16.6%, heavy oil, coke consumption accounted for 8.8%. In addition, the zinc and cobalt concentrates used each year contain 57,300 tons of sulfur and generate 26,400 tons of standard coal during the roasting process. The overall thermal efficiency of the plant is only 40%, preliminary statistics of waste heat resources 147,000 tons of standard coal, we can see that I plant consumption, waste heat
