Abstract: To reduce the net coal consumption under low loads of the units, in this article, the optimizations and technical retrofits on energy saving of Huaneng Ruijin Power Plant in recent years are discussed thoroughly and the operation optimization plans and the technical retrofit items for low loading conditions are put forward. The practices indicate that when at the low loading operation, the two-mill operation, pressure curve optimization, cold-end optimization, and condensate pump optimization are more operable to achieve energy saving on the premise of ensuring the security and reliability of the units. The discussion results are valuable for popularization.

Key words: thermal power unit, low load, two-mill operation, pressure curve, cold-end system, condensate pump
