ABSTRACT:
The invention contemplates improvement and economy in demineralization of the total flow of recirculating water in a steam-generating system which includes a condenser for recovery and recirculation of feed water. This filter demineralizer operates on a relatively small fraction of the total flow, being available as a relatively small flow of high-temperature water collected from steam-generator blow-down, from steam-separator drainage, or from other high-temperature drainage from a steam-utilization device. The purified effluent from the filter demineralizer is returned to the circulatory system for supply as pumped feed water along with other feed water pumped from condensate accumulation.
