Recently，Cooling Tower of Hunan Yiyang Power Plant Phase III Two Million Units Capacity Expansion and Upgrading ProjectVThe first truss of section steel column，It was successfully hoisted in place by Zoomlion crawler crane.，When completed, it will be the highest in the world.、The largest high-level water collection cooling tower。

It is understood that，Hunan Yiyang Power Plant Phase III Two Million Units Project is Building World Power Generation Efficiency、Coal consumption index、Two 1 million kilowatt high-efficiency ultra-supercritical secondary reheat coal-fired generating units with the most advanced environmental protection indicators，Adopt“Two machines and one tower”Scheme of high-level water-collecting cooling tower，Tower top elevation 242.4 meters，The watering area is 22500 square meters.，Zero meter diameter 183.63 meters。Hoisting this timeVProfile steel column height 20.5 meters、Single frame weight 31.182 tons，Have a high height、The hoisting weight is large、Many special-shaped rods and the like.。

The construction unit, China Nengjian Anhui No.2 Electric Power Construction Company, adopts factory customized processing.、Flow assembly on site，Cooperate with the joint operation of the flat bridge in the tower and the elevator，FinishVConstruction of section steel column and steel ring beam。This assembly is safer.、Efficient，It also puts forward more stringent requirements for cranes.。Stable lifting by Zoomlion crawler crane、Accurate landing point，Successfully completed the first hoisting.，Press the accelerator key for the project construction！

After the completion of the third phase project of Yiyang Power Plant，It will become the largest thermal power plant in Hunan Province.，Annual power generation can reach 20 billion kilowatt-hours.，At the same time，Power plant will build 2 million kilowatts of new energy projects。At that time，Through the integrated operation of coal and electricity，It will further improve the energy structure of Hunan Province.，Improve the peak regulation capacity and safe operation level of the power grid。
