Steam and Condensate - Plumbing Engineering Services Design Guide

Steam and condensate chapter from the Plumbing Engineering Services Design Guide.

Steam is water which has taken in heat and passed through to the complete vaporization stage. At atmospheric pressure, boiling water and steam have the same temperature - 100°C.

As in practice, a differential pressure is required to cause steam to flow along a pipe, steam is normally supplied at a pressure, some way above atmospheric pressure. Above atmospheric pressure the steam temperature rises; this temperature gradient makes the steam more useful as a heating agent.

This section of the Guide covers all things steam and condensate.

Contents include:

• Steam tables
• Design considerations
• Steam and condensate traps
• Steam separators
• Strainers
• Steam trap checking
• Air venting
• Reduction of heat losses
• Allowance for expansion
• Condensate return
• Handling condensate.
