Preheating water before water heater
WebJan 1, 2009 · This system captures heat from a heat-reclaim chiller and provides water at the temperature required by an application. To ensure stable hot-water-temperature control, loop volume should be no less than 6.0 gal. per ton of heating capacity within a water heater and preheat storage tanks and connecting piping. WebOne type of feedwater heater for preheating the water before entering a boiler operates on the principle of mixing the water with steam that has been bled from the turbine. For the states as shown in Fig. P7.112, calculate the rate of net entropy increase for the process, assuming the process to be steady flow and adiabatic.
