Energy Conservation-As it Applies to Condensate Return Systems

Abstract

Valuable heat energy in condensate is wasted when it is vented to the atmosphere in the form of flash steam at many condensate pumping stations. This heat energy may be recovered and put to use if the pumping station can handle condensate temperatures above 212 °F. The Johnson Corporation has such a condensate pumping station that can handle multiple temperatures and pressures called the LIQUI-MOVER. The Liqui-Mover can be utilized in one of three types of condensate return systems: open, closed, and flash. The closed and flash type condensate return systems are the most energy efficient. The report will show how the Johnson Liqui-Mover operates and how this system has been and can be used to recover wasted flash steam.
