北京铜厂压延铜杆时的铜锭加热,现已改用掺水15～20％的重油作燃料。这项措施的实施,可节油12～15％,若以年产三万吨铜杆计算,全年可节油250吨。重油掺水的具体方法是:将储油箱的油和水箱内的水以含水量15～20％这样的比例,通入同一管道,经CB-46型齿轮油泵搅拌后送入乳化罐存放。乳化罐内经初步乳化的掺水重油由另一CB-46齿轮泵再次搅拌后输送到铜锭加热炉前,其中仅6％从油咀 Beijing Copper Plant rolled copper rod when the copper ingot heating, now switched to 15 to 20% water for heavy oil fuel. The implementation of this measure can save 12 to 15%, if an annual output of 30,000 tons of copper rod calculation, the annual fuel-efficient 250 tons. The specific method of mixing heavy oil is: the oil in the tank and the water tank to the water content of 15 to 20% of this ratio into the same pipe, the CB-46 gear pump stirred into the emulsion tank storage. Emulsified tank by the initial emulsification of water-mixed heavy oil by another CB-46 gear pump again after mixing the copper ingot heating furnace, of which only 6% from the oil Tsui
