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

Yearly heat loss in amount of coal or oil consumption for insulated and uninsulated steam pipes at different dimensions and operation times.

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

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