1.总能耗的变化联邦德国整个工业、非金属矿工业及重粘土行业的能耗变化情况列于表1。1982年重粘土行业能耗下降了22.5％,跃为非金属矿节能最显著的行业之一。将其折成标准煤共节能288000吨,仅水泥行业节能355000吨标准煤而超过此值。1982年水泥行业总耗能3680000吨标准煤,重粘土行业共耗能2182000吨标准煤。同1981年相比,1982年砖产量下降了14％(体积比),屋面瓦产量同期上升了8％。两者
1. Changes in total energy consumption The energy consumption changes of the entire industrial, non-metallic mining industry and heavy clay industry in the Federal Republic of Germany are listed in Table 1. In 1982, the energy consumption of the heavy clay industry dropped by 22.5%, and the energy leap to non-metallic minerals was the most significant One of the industries. Converted into a total of 288,000 tons of standard coal energy savings, energy-saving 355,000 tons of standard coal in the cement industry and more than this value. In 1982, the total energy consumption in the cement industry was 3.68 million tons of standard coal and heavy clay industry consumed a total of 2182000 tons of standard coal. Compared with 1981, brick production in 1982 fell by 14% (volume ratio), roof tile production over the same period rose by 8%. Both
