ABSTRACT:
A hybrid preheat/recirculating steam generator is provided with a divided downcomer such that cold feedwater is preheated by being mixed with recirculating water and the mixture is introduced on the cold leg side of the tube bundle by natural circulation. A partition plate between the hot leg and cold leg sides of the tube bundle keeps the mixture on the cold leg side from mixing with the remainder of the recirculating water which enters on the hot leg side of the bundle in the usual manner.
