How Do Steam Boilers Work? | Hunker

Steam boilers provide efficient heat for homes and industrial settings. In most cases, raw water is fed into the boiler from a pipe system. That water is then purified to clean it of any debris. Next, the water is fed into a de-aerator that removes air, then is fed into the boiler tank and heated.
