Condensate Recovery

Relaying condensate back to the boiler house reduces costs. Pipe sizing and layout is discussed for drain lines, discharge lines, and pumped lines. The effects of lift and backpressure are explained; and how to reduce overall costs by utilising flash steam.

  1. Introduction to Condensate Recovery

    An introduction to the reasons for condensate recovery and return, including energy costs, water charges, effluent restrictions and water treatment costs. Includes sample calculations for potential savings.

  2. Layout of Condensate Return Lines

    Considerations surrounding the design and layout of condensate return pipework, including drain lines to steam traps, discharge lines from traps, common return lines and pumped return lines. Includes the effect of trap types used, the effect of different pressures and discharging condensate into flooded mains.

  3. Sizing Condensate Return Lines

    A guide to sizing condensate lines to and from steam traps, including examples and calculations using the condensate pipe sizing chart.

  4. Pumping Condensate from Vented Receivers

    A basic introduction to pumping terminology, including vapour pressure and static head. Includes a description of the operation, application and comparable benefits of electrical centrifugal and mechanical condensate pumps, with sizing examples for pumps and pump discharge lines.

  5. Lifting Condensate and Contaminated Condensate

    Recommendations for special circumstances, including lifting condensate to a higher level return line, and dealing with contaminated condensate.

  6. Flash Steam

    The benefits of recovering flash steam, how it is done and how flash steam can be applied elsewhere in the plant to maximise overall efficiency.
