Converting From Steam to Hot-Water Heating | Sobieski

Steam-based heating has a long history as a reliable source of heating for commercial and residential applications. However, in some cases, converting from steam to hot-water heating may be a better choice. If you're considering making the switch, here are some important points to keep in mind.

Degassing Boiler Feed Water in China with Liqui-Cel

Proper treatment of boiler feed water is an important component of a boiler system. As steam is produced, dissolved solids become concentrated and deposit inside the boiler. This leads to poor heat transfer and efficiency reduction of the boiler. Dissolved gasses, such as oxygen and carbon dioxide, will react with the metal surfaces inside the

Boiler | Engaged in Thermodynamics

In low water conditions, the boiler does not receive the amount of feedwater needed to keep it running at safe conditions. Because water acts as a cooling agent inside boilers, low water levels inside the boiler cause the pressure in the boiler to rise. The water absorbs heat created through combustion and turns it into steam.

Heating System Conversion: Steam to Hot Water

Steam-based heating systems are common in New York City, especially in pre-war apartments and other old buildings. However, steam boilers and radiators tend to be inefficient due to their age and design, and conversion to hot water can yield considerable energy savings.

US Patent for Apparatus for supplying feedwater to a steam

Apparatus for supplying feedwater to a steam generator, such as a waste-heat boiler, includes the feature of degassing feedwater at a degassing station by way of a suitable degassing means, the feedwater being degassed by being heated to boiling temperature. Prior to reaching the degassing means at the degassing station the feedwater supplied thereto is heated by being placed in a heat

What You Need to Know About Residential Steam Boilers

The steam boiler is an old convection heating technology dating back over 200 years and is commonly found in older homes. Because steam boilers operate at a higher temperature than hot water boilers they are inherently less efficient than their hot water cousins.

Application Note: Monitoring Steam Purity in Power Plants

Plants with drum-type steam generators both conventional boilers and heat recovery steam generators (HRSGs) maintain steam purity by taking advantage of the physical separation that occurs between water and steam in the drum. As the water boils, it forms a steam-water mixture, which upon entering the drum separates into steam and water.

With vacuum degassing, water can also be degassed below 100°C by boiling. Creating a corresponding negative pressure (partial vacuum) in the degassing unit enables the boiling point to be reached as early as in the 30-80 °C range. This degassing process is suitable when no hot steam is available for operating thermal pressure degassing.

Typically, 0.5-3.0% by volume concentration in water is adequate. For tanks, it is recommended that a 3D spray nozzle system be used to apply the product. The number of nozzles used will depend upon the diameter of the unit to be degassed, however, the spray pattern should cover the entire diameter of the vessel.
