一、前言 目前,我国各大火电厂对粉煤灰的处理一般采用水力管道输送,在平原或山谷中贮放。国外一些电厂采用了干贮灰的方法,即将干灰加水压实后贮放,这种方法对于缺水地区更有实际意义,干贮灰方法在我国还处于试验阶段。北京高井电厂所进行的干贮发现场碾压试验方法步骤是:用搅拌机将灰加水搅拌,用装有密封仓的专用汽车运至现场,再由推土机将灰 I. INTRODUCTION At present, the treatment of fly ash by major thermal power plants in China is generally carried out by hydraulic pipelines and stored in plains or valleys. Some foreign power plants have adopted the method of dry storage of ash, that is, dry ash is added after compaction and storage. This method is more practical for water-scarce regions. The dry ash storage method is still in an experimental stage in China. The steps of the roller compaction test method for the dry storage site conducted by the Beijing Gaojing Power Plant are as follows. The ash and water are stirred by a mixer, transported to the site by a special vehicle equipped with a sealed bin, and then the bulldozer will put the gray
