摘要
大唐国际绍兴江滨热电安装2台M701F4型燃气—蒸汽联合循环452MW机组。在发电机组真空系统严密性试验优良的水平基础上实施真空系统的节能技术升级改造,在抽真空母管上并接一台小型高效罗茨-水环真空泵组,使用小型高效罗茨-水环真空泵组替代原真空泵组维持机组真空,降低厂用电,提高汽轮机热效率。
Datang International Shaoxing riverside thermoelectric installation 2 M701F4 type gas steam combined cycle 452 MW unit.On the basis of the excellent level of the vacuum system tightness test of the generator set,the energy-saving technology of the vacuum system is upgraded,and a small and efficient roots water ring vacuum pump group is attached to the vacuum tube and a small efficient roots water ring vacuum pump group is used instead of the original vacuum pump unit to maintain the vacuum of the unit,and the power consumption of the plant is reduced.The thermal efficiency of a high steam turbine.
