摘    要:介绍了目前大型燃煤电厂贮煤场的设计形式以及条形煤场和全封闭圆形煤场常用堆取料设备,即悬臂式斗轮堆取料机和圆形煤场堆取料机。结合北方某大型燃煤电厂的工程设计实例,对该工程贮煤场采用全封闭条形煤场及采用同容量的全封闭圆形煤场的2种贮煤形式进行了技术性能和经济性比较,给出了2种贮煤形式的适用情况,即在地质条件较好情况下,2种贮煤方案总投资相当,但在地质条件较差情况下全封闭圆形煤场总投资要高于全封闭条形煤场。结合该电厂的实际情况,最终选用全封闭条形煤场。

关 键 词:全封闭条形煤场  全封闭圆形煤场  堆取料机

Abstract:The design forms of coal yard in large-scale coal-fired power plant is introduced, and the operation way is described about the common stacking and reclaiming equipment applying on the strip coal yard and enclosed circular coal yard, i.e. cantilever-type bucket wheel stacker-reclaimer and circular stacker-reclaimer. According to the design of a power plant in North China, compared the enclosed strip coal yard with the enclosed circular coal yard from technical and economical, applicability of two kinds of coal yard is analyzed. In the case of the geological conditions are better, the investment of two kinds of schemes is equivalent. But in the poor geological conditions, the total investment of the enclosed circular coal yard is higher than the total investment of enclosed strip coal yard. According to the actual situation of the power plant, the enclosed strip coal yard is adopted.
Keywords:the enclosed strip coal yard  strip coal yard  enclosed circular coal yard  enclosed coal yard  stacker-reclaimer
