Application example 2
Extraction back pressure turbine in the industrial and local heating supply.
Doubly efficient: Spilling supplies a food production company with process steam and ensures the provisioning of heat for the local heating supply.
To this purpose, a wood chip-fired boiler was combined with a Spilling extraction-back-pressure turbine.
Benefits for the customer
- Cost saving due to supply of domestic electricity and heating
- Revenue from supplying heat energy to the local consumers
- Revenue from feeding electricity into the public grid
