A boiler is a closed vessel that is used to heat fluids such as water. The fluid does not usually have to boil during the heating process. In such cases where the fluid does not actually boil, the term furnace is used more, especially in Sutton, WV. Heating the fluid produces high pressure steam used for various heating processes and applications. Among those applications for which the steam from commercial and industrial boilers is used include central heating, boiler-based power generation and water heating. It is also used for cooking and sanitation.
There are several types of boilers in use today. The type of boiler determines the type of material it is made from. Steel and other alloys of steel are usually used in making the pressure vessel of the equipment. Stainless steel, especially those of austenitic types are not used in making parts that come in contact with water or other fluids. This is because of corrosion and stress corrosion cracking.
Ferritic stainless steel finds use in making components that do not get wetted by water. In certain applications and smaller models, ease of fabrication of brass and copper makes them to be used. Copper has been used for a long time, but it is losing popularity because it is too expensive to be economical. Thus steel, being a cheaper alternative, is taking over. There are also applications where wrought iron and cast iron are still in use including making domestic water heaters.
Initially, joining of various components on the equipment was done through riveting. However, as steel gained more popularity in the twentieth century over wrought iron, welding took over. The labor force required for welding is way less than one needed for riveting and welding is also faster.
However, wrought iron presents several advantages over steel in many aspects. First, corrosion is much slower in appliances made from wrought iron than those made from steel. Susceptibility to localized pitting and stress-corrosion are also much less in components constructed from wrought iron. Because of those advantages, wrought-iron boilers can stay much longer than those constructed from steel and joined through welding.
A boiler uses different kinds of fuels for generating heat. Among them are oil, natural gas, wood, and coal. However, technological advancement has made it possible for production of electric steam models which rely on immersion-type or resistance heating elements. There is also increase in popularity of nuclear fission for generating steam used in power generation purposes.
The manufacture and application of a boiler requires a lot of safety measures to be taken. As such, bodies exist to set standards and codes that must be followed in all production and application processes. The American Society of Mechanical Engineers is an American regulatory organization that sets rules and directives and enforces compliance in the industry.
Energy is effectively moved from one place to another by the steam generated from a boiler. However, such transfer of energy can only occur if the pipes are designed and made suitably. Otherwise, if the pipes burst or become compromised, they could lead to serious accidents. Such accidents lead to deaths and damage of property.
