  • Boiler and Feedwater Pump Efficiency Optimization

    The feedwater pump discharge pressures can vary between 875 and 1000 psi depending upon boiler demand. Differential pressure between the two points can be up to 200 psi, (or even higher in system upset conditions). This differential pressure must be accurately measured, without regard to the 800 psi and above changing boiler drum static pressure.Get Price

  • Steam vs Electrical Condensate Pumps

    The temperature of condensate at the outlet of the electrical pump drops to 55-75 deg. C leading to an energy loss of 3-4% of the total energy input in the boiler. With this configuration the feed water temperature is in the range of 50 to 70 deg. C. So, out of the total 20% energy available in condensate and flash steam, only 8% energy is Get Price
