能耗量在全省工交部门中占第四位的湖北省建材行业,近两年来,在抓好能源基础管理的同时,根据本行业的生产特点,大力开展以节能为中心的综合技术改造工作,先后推广了26项节能的新技术、新工艺、新设备。水泥工业节能重点是把土窑或普通立窑改造为机械化立窑,现巳改造了20多台。经测定,每台机立窑比普立窑的煤耗降低20%,熟料质量提高100到200标号,产量增加一倍。一些基础较好的大中型水泥企业,则着重推广新
The construction materials industry in Hubei Province, which has the fourth-largest energy consumption in the province’s industrial and transportation sector, has been focusing on energy-based management. At the same time, it has vigorously carried out comprehensive energy-conservation-based technological transformation work in accordance with the characteristics of the industry’s production. , Has promoted 26 energy-saving new technologies, new processes, new equipment. The key point of energy saving in the cement industry is to transform an earth kiln or ordinary shaft kiln into a mechanized shaft kiln. More than 20 units have been transformed. It has been determined that the coal consumption of each machine shaft kiln is reduced by 20% compared with that of the pu kiln, and the clinker quality is increased by 100 to 200 labels, and the output is doubled. Some well-established large and medium-sized cement companies focus on promoting new ones
