Steam Pipes - Fuel Consumption due to Heat Losses over a Year

Sponsored Links

Yearly heat loss per meter pipe line is estimated for steam pipes with pressure 6.5 bar (7.5 bar abs, 168oC) and surrounding air temperature 20 oC.

Increasing the steam pressure increases the temperature and influences energy consumption and heat loss.
