Reducing steam consumption at the point of use will result in even more savings at the boiler.
The answer is…
The energy that was saved (steam savings) at the point of use was provided to the system through the boiler, which experiences losses. For example, if boiler efficiency is 80% then saving 100 units of steam energy at the point of use will reduce fuel consumption 100/0.8 units of fuel energy or 125 fuel units. This does not consider condensate losses and other system effects.
Additional savings can result from:
- Maintenance activities
- Water purchases
- Environmental impacts
