Boilers

Boilers

are closed steel vessels for heating and vaporizing water (or other fluid) into steam, often driving turbines or generators, or heating buildings. Most boilers are welded alloy-steel structures (but not stainless steels), per many industry codes. Most are fired (fueled) with oil, coal, or natural gas. For greater thermal efficiency, superheater boilers operate at 2400– 2900° F and several hundred PSI. For greater turbine life, supercritical boilers operate at about 3200 PSI.
