某火力发电厂贮灰场调洪演算研究

Study of flood control calculation of ash storage yard in a thermal power plant

火力发电厂中灰场是用以贮存燃煤锅炉排放灰渣的堆放场地,通常布置周边山体的山谷地带,由于汇水面积大,降雨期洪水将直接威胁灰场坝体的安全性.文中从水量平衡方程出发,采用静库容调洪,根据库容曲线、洪水入流情况及泄流情况,对设计标准期调洪库容和最高洪水位进行计算,从而评价灰场的防洪安全性.

The ash yard of thermal a power plant is a storage site for storing ash and slag discharged from a thermal boiler and is usually arranged in the valleys of surrounding mountains.Due to the large catchment area,flood during the rainfall period will directly threaten the safety of the ash yard dam.Based on the water balance equation,the static storage capacity is adopted to adjust the flood.According to the storage capacity curve,flood inflow conditions and discharge conditions,the flood control storage capacity and the highest flood level during the design standard period are calculated to evaluate the flood control safety of the ash yard.
