Back pressure within a steam system is cause by ALL of the following EXCEPT which one: 1.Back pressure from lift – every 2 feet of lift takes 1 psi 2.Back pressure from flow – pressure drop is caused by flow 3.Back pressure from equipment – check valves cause back pressure 4.Back pressure from bad traps […]
With rising fuel costs, replacing unreliable, high-maintenance older burners with newer ones can provide high efficiency savings. Replacing an older burner, even with the same controls, will automatically improve the boiler operating efficiency. As the burner operates, the linkage and valves wear and over time, create some gaps in the linkage connections. Fuel pressure regulating […]
Armstrong recently announced that the Armstrong International – VERIS Flow Measurement Group’s sales office and manufacturing plant relocated approximately 12 miles directly east from Niwot, Colorado to Fredrick, Colorado. The relocation, which began in early September with manufacturing employees and machinery, is expected to be completed by the end of 2017. The new, four-year-old space, […]
During maintenance, the insulation that covers pipes, valves, and fittings is often damaged or removed and not replaced. Pipes, valves, and fittings that are not insulated can be safety hazards and sources of heat loss. Removable and reusable insulating pads are available to cover almost any surface. The pads are made of a noncombustible inside […]
The Aar-O-Vent® high performance air and dirt separator is a product we highly recommend as a way to increase performance and protect against corrosion in hydronic systems. Heating/cooling system efficiency and component life is greatly dependent on water quality. Air and dirt particles can cause pump cavitation, corrosion and increased component wear. In a closed […]
What is the boiling point of water at 2000 feet above sea level? 218º – The higher the elevation the more heat it takes (3º for every 1000′) 214ºF – It takes a little more heat (1º for every 1000′) 212ºF – The boiling point is the same no matter what the elevation is 208ºF […]
Developed from direct contact water heating science, which was first introduced more than two decades ago, Complete Thermal Exchange (CTE) technology has revolutionized high efficiency water heating methods, rapidly become the new standard in water heating and energy savings. While traditional direct contact water heating can offer significant energy savings when compared to a conventional […]
Boiler “short cycling” occurs when an oversized boiler quickly satisfies process or space heating demands, and then shuts down until heat is again required. Process heating demands can change over time. Boilers may have been oversized for additions or expansions that never occurred. Installing energy conservation or heat recovery measures may also reduce the heat […]
The purpose of Booster coils is to “boost” heat to a space. The coil heats or reheats the air using hot water anywhere from 140˚ F – 200˚ F. For many applications they can be an ideal solution because they produce high capacity with limited water quantity. How did the term “booster” originate? Most heating […]
