Usage of energy in laundries
In laundries, energy is necessary to generate process heat (steam, hot water). Energy sources are gas, electricity and fuel oil (extra light) and fuel oil (heavy: S). gas and electricity are used for
- ) direct machine heating as well as for
- ) indirect application to heat transfer media
Heavy fuel oil is normally applied in industrial plants only due to complex legal requirements for its application
Distribution of energy in laundries
Energy sources in laundries
High pressure steam:
Steam pressure > 1,0 bar, usually: 8 -12 bar (above atmospheric pressure), temperatures: 175 - 191 °C
Steam characteristics
• high heat capacity
• excellent transfer capacity
• constant efficiency at max. power
Application technology
+ direct steam flow (washing and steam process, therefore short heating up of heating washing liquor)
+ high efficiency (economic)
+ reserve at high peaks of consumption (big boiler)
- high acquisition costs
- inspection by legislation required
Low pressure steam:
Steam pressure 0,5 - 1,0 bar, usually: 0,5 bar (above atmospheric pressure), temperatures: max. 120 °C
Steam characteristics
• high heat capacity
• excellent transfer capacity
Application technology
+ short heating up intervals
+ simple handling and maintenance
+ low acquisition costs
+ no legal requirement of inspection (TÜV),registration of boiler only
- temperature max. 120 ºC, therefore inapplicable for mangles, tumblers,presses etc.
