How the natural circulation is achieved in boiler by

This seems like a simple question but the complete answer is very complicated. At its simplest, natural circulation is established by heating some water more than another part. Hot water (and especially steam) is less dense than cold water so the

3 Types of Circulation In Boiler - Water Treatment Basics

This article is focused towards the author experience in the design and trouble shooting of Boilers related to the principle of natural circulation. Inadequate circulation causes tube failures. Poor circulation ni a boiler may be due to design defect or improper boiler operation. In this paper the factors affecting the circulation are summarized. Further case studies are presented.
