摘要:

大中型火力发电厂粉煤灰储存量很大,传统的露天灰场很难满足环保要求,而常规半封闭储存灰场一定程度上降低了干灰的综合利用价值。提出了包含1座大型粉煤灰钢板仓以及1座拱式钢网架封闭灰棚的组合式封闭灰场方案,与露天干灰场方案相比,该方案投资建设成本较低,能有效解决灰场建设及运行中出现的环境污染问题,并能显著提高粉煤灰的综合利用水平,社会效益和经济效益显著。

Abstract:

Fly ash storage of large and medium sized thermal power plant is quite substantial. The traditional openair yard is hard to meet the requirements of environmental protection, and conventional semiclosed storage yard to a certain extent reduces the comprehensive utilization value of dry ash.It proposes a scheme of combined closed ash yard which contains a large steel silo of fly ash and a steel archframe closed ash shed.Compared with the outdoor dry ash field solution, the scheme's captalized cost is low.The scheme can effectively solve the environmental pollution in the  procedure of construction and operation of ash yard and significantly improve the level of the comprehensive utilization of fly ash. Its social benefit and economic benefit is remarkable.
