  • Using cold boiler feed water for energy recovery

    In this layout, 7.4 Gcal/h is recovered by heating boiler feed water, while 17.4 Gcal/h is wasted. In the current project, cold boiler feed water (30–50°C) will be supplied from the membrane deaerators to this unit through existing feed water pumps. The driving force for heat transfer will be increased in exchanger E-203 (see Figure 1) and Learn More

  • Introduction to Condensate Recovery | TLV - A Steam

    Reducing boiler fuel needs through condensate recovery leads to less air pollution by lowering CO 2, NO x and SO x emissions. Additionally, condensate recovery lines can also limit vapor clouds to reduce noise generated from atmospheric condensate discharge and help prevent build-up of water on the ground, considerably improving a plant's Learn More

  • Condensate Recovery | Flash Steam | Spirax Sarco

    Occasionally, during summer conditions it may be preferable to bypass the flash system with a manual valve (not shown in Figure 14.6.9). The condensate and its associated flash steam will then pass directly to a condensate receiver, where the flash steam will be vented to atmosphere.
