摘要
基于全国涉及石灰生产的企业全口径统计数据,分析中国2007年石灰生产的基本特征,探讨了石灰产量统计的不确定性和来源。2007年,中国石灰生产的企业共6 154家,涉及9 327座石灰窑。总产能为2.27亿t,共生产石灰1.06亿t,企业平均产量为4 000 t/a,企业生产每吨石灰平均能耗水平为163 kg标准煤。中国约有两千八百多万吨的石灰生产很难通过正规渠道统计上来,也意味着这些产量很可能是基于非常简易和高能耗的石灰土窑生产的。
Based on an inclusive statistical survey, China lime production and uncertainty were analyzed. In 2007, there were 6 154 plants and 9 327 lime kilns in China, which hold 0. 227 billion ton of production capability and produced 0. 106 billion ton lime. The average annual production and energy consumption of plants were 4 000 t/a and 163 kg coal equivalent/lime respectively. Roughly 28 million production of lime was not registered on official sources, which means that these productions were highly probably produced with backward equipment and high energy consumption.
