Steam Community :: Guide :: Driving and Firing Steam

2013/1/3 · Water starts in the tank (or the tender) and we use something called an Injector to take water at normal atmospheric pressure and inject it in to the very high pressure environment inside the boiler. Injectors work by using Steam to force the water in - there's lots of info on the web about how they work.

Boiler explosion - Wikipedia

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level.

Working Principle | Boilers Guide

When water at atmospheric pressure is boiled into steam its volume increases about 1,600 times, producing a force that is almost as explosive as gun powder. This causes the boiler to be an equipment that must be treated with utmost care. The boiler system

Water Handbook - Preboiler & Industrial Boiler Corrosion

Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.
