Classification of Steam Heating Systems

Steam systems carries heat through pipes from the boiler to consumers as heat exchangers, process equipment etc.

Condensate Generated in Insulated Steam Pipes (kg/h per 100m)

Heat loss from steam pipes generates condensate which must be drained from the system

Condensate Generation in Cold Steam Pipes - SI Units

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

Condensate Generation in Cold Steam Pipes - Sizing Steam Traps

When cold steam pipes are heated up they generate huge amounts of condensate that must be drained away from the pipe through steam traps - in Imperial Units
