Steam boiler plants Thermal oil / fluid heat ing systems

Steam pressure at 250 °C39,7 bar

Vapor pressure at 250 °C0,016 bar

Higher risk due to a higher system pressure Lower risk due to near to zero system pressure

Water Treatment plant needed to minimize corrosion in vessels & pipework

Thermal fluid (organic heat transfer oil) eliminates corrosion problems

Downtime / auxiliary heating system neededNo downtime heating needed due to a lower

freezing point of the fluid

The open heating circuit causes a loss of 10 … 20 % Closed system, no losses

System temperature control goodSystem temperature control better due to higher

system temperature differential

Service life expectancy is about 15 – 20 years Service life expectancy is over 25 years

High maintenance requirements Low maintenance requirements

High operating expenses Low operating expenses

Thermal oil heat ing systems

Thermal oil heat ing is an indirect heat ing in which a liquid phase heat t ransfer medium(mineral-based or synthet ic “thermal oil”) is heated by a fluid heater and circulated within aclosed loop system over the heat consumer(s).
