Natural Circulation - an overview ScienceDirect Topics

This problem could be eliminated by forced or controlled water circulation. This system introduces boiler circulating water (BCW) pump(s) in between the steam drum and the waterwall which enables the cold feedwater from the drum to get an additional pressure head to overcome the limitations experienced through natural circulation.
