Plant Operations Require A High Steam Quality - Swagelok

The boiler operation uses chemical energy from a fuel source to deliver energy to the boiler . water. Inside the boiler, liquid gains energy from the combustion process and changes state into saturated steam. Water enters the boiler at point A and the water gains sensible energy (hf) to point B. The change of state is referenced as point B on

Water heating - Wikipedia

Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.. Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers.

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.

Pressurised Hot Water - Megaflo Unvented Hot Water Systems

The boiling water will turn to steam and evaporate into the atmosphere. With an unvented system, the water is typically held under pressure at 3 bar. If the thermostat fails, and the water continues heating, it could reach 100°C. In a vented system the water would boil and evaporate, but remain at 100°C.
