Generation of Condensate in Cold Steam Pipes - SI Units

Huge amounts of condensate generated when cold steam pipes are heated up must be drained from the pipes

Sponsored Links

When cold steam pipes are heated up huge amounts of condensate are generated and must be drained from the pipes. It is important that steam traps are designed to handle start-up loads.

The diagram and table below can be used to roughly estimate the load of warm-up condensate generated when a steam system is heated up.
