# Steam Heating Systems - Classifications

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

Steam is commonly used to distribute heat from a boiler to consumers like heat exchangers, process equipment etc. Steam is also used for heating buildings.

Steam systems can be classified by pressure, method for returning condensate and/or pipe lay out.

### Classification of Steam Systems by Pressure

Its common to classify steam systems as

• High pressure above 20 kN/m2 (3 lb/in2)
• Low pressure up to 20 kN/m2 (3 lb/in2)
• Vacuum

### Classification of Steam Systems by Method of Condensate Return

Steam systems can be classified as

• Gravity
• Mechanical

### Classification of Steam Systems by Pipe Lay Out

Steam systems can be classified by pipe scheme:

• One pipe or two pipe
• Up-feed or down-feed
