一、水泥工业的能源现状与任务 在当今十大经济大国中,同样生产1美元的国民生产总值能耗最早的是中国,我国能耗是法国的5倍,日本的4.4倍;巴西的3.8倍,印度的1.6倍。建材工业是能耗大户,1988年全行业耗用11600万吨标煤,占全国能源的十分之一,其中水泥工业耗用4120万吨标煤占全行业能耗的35.52％,因此做好水泥工业的节能工作是一件刻不容缓的大事。 传统的水泥生产方法分立窑和回转窑两种。回转窑生产又分干法、半干法及湿法,前两
First, the cement industry’s energy status and tasks In the top ten economic powers today, the same GDP of 1 US dollar to produce the earliest energy consumption is China, China’s energy consumption is 5 times that of France, Japan 4.4 times; Brazil’s 3.8 Times, India 1.6 times. Building materials industry is a large energy consumption, in 1988 the entire industry consumed 116 million tons of standard coal, accounting for one tenth of the national energy, of which 41.2 million tons of standard coal consumption of the cement industry accounted for 35.52% of the industry-wide energy consumption, so do Energy conservation in the cement industry is a pressing event. Traditional cement production methods and rotary kiln separate kiln two. Rotary kiln production is divided into dry, semi-dry and wet, the first two
