How Does a Boiler Pressure Vessel Work?
A sealed container that is intended to hold liquids or gases at a different pressure from the atmosphere around it is known as a pressure vessel. Contemporary boiler pressure vessels are typically composed of steel. Older boiler vessels were composed of wrought iron, copper or cast iron, and held together by rivets. Boiler pressure vessels, if punctured or flawed, can cause serious and even fatal accidents. This is a result of the difference in the pressure levels between the substance inside the container and the substance outside the container. If breached, the danger lies in the reaction, as the substance inside the container regulates to the same pressure as the atmosphere outside the vessel. If the substance inside is compressed, and stored at a higher pressure than the air outside, the substance will rush outwards if the vessel is punctured, creating an explosion. If the substance inside is at a lower pressure, it will create a suction effect if punctured. Pressurized containers
