CHAPTER TWO: Boiler Operation Maintenance & Safety Study Guide

The high pressure feed water is supplied to the boiler through this valve. This valve opens towards the boiler only and feeds the water to the boiler. If the feed water pressure is less than the boiler steam pressure then this valve remains closed and prevents the back flow of steam through the valve.

Types of High Pressure Boilers | Sciencing

Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to large furnaces

High Pressure vs. Low Pressure Boiler

Nov 23, 2011 · By definition, a high pressure boiler is one that operates above 15 psi, while a low pressure boiler is one that operates at 15 psi or lower. Steam heating systems run with even lower pressure, typically at less than 1 psi in all. However, these types of boilers are less common (especially in newer homes), and operate using a different system.
