Abstract:

Aiming at the question of the energysaving benefit of the lowpressure economizer installed in power generation unit, taking a system reformation

project of a power plant, in which the lowpressure economizer was installed in a 300MW grade unit, as example, the energysaving effect obtained by

theoretical calculation was compared with the site measured result, and the energysaving effect of the lowpressure economizer applied in 300MW grade unit

was analyzed objectively.

Key words: low-pressure economizer, outlet gas temperature, energy-saving
