ASME Code quality control requirements. Capacities of valves with set pressures of 15 psig (1.03 barg], or higher, are certified by the National Board of Boiler and Pressure Vessel Inspectors. These attributes are assured by the presence of an ASME Code Symbol Stamp and the letters NB on each pressure relief valve nameplate. Lower set pressures are

Design of a High-Temperature-Hot-Water-Plant Expansion

The BTU/hour to Boiler Horsepower calculator is used to help size both steam and hot water boilers. This calculation translates the heat transfer input requirement to BHP. To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.

75 ton gas steam boiler for power generation, gas fired

Feb 15, 2019 · High-temperature hot-water (HTHW) plants are typically designed to operate at temperatures ranging from 350°F to 420°F. The system pressure must be at least 25 psig above the saturation pressure of the high-temperature water's maximum temperature to prevent pump cavitation and flashing of superheated water to steam.
