System Selection for Recirculating Cooling Water Treatment of Ultra-Supercritical Fossil-Fueled Power Plants

Abstract:

The water source of one ultra-supercritical fossil-fueled power plant is municipal reclaimed water and reservoir water. Techno-economic comparison of several schemes for recirculating cooling water treatment system show that the side stream lime softening treatment system is an optimal scheme. It has comprehensive functions of scale prevention, corrosion prevention and removing suspended solids, and the system combines the make-up water softening treatment system and the side stream suspended solid removal treatment system of recirculating cooling water, which reduce the investment and the operation cost, and meet the requirement of maximum water saving. The side stream lime softening treatment system is energy saving and discharge reduction.
