Working Principle | Boilers Guide

Working Principle. Steam boilers produce steam that flows through pipes from areas of high pressure to areas of low pressure, unaided by an external energy source such as a pump. Steam utilized for heating can be directly utilized by steam using equipment or can provide heat through a heat exchanger that supplies hot water to the equipment.

Basic Parts of a Boiler | Hunker

A boiler is a self-contained combustion system that heats water. The hot water or steam produced by a boiler is then used in heating systems. Although designs vary, a boiler has four main parts: the burner, the combustion chamber, the heat exchanger and the pluming apparatus. The burner initiates the combustion reaction within the boiler.
