Application example 1
Utilising industrial exhaust heat in a German steel work.
A German steel work relies on the specialist Spillling in order to optimally utilise the saturated steam at 19 bar arising from a heat treatment process: The existing steam generation was retrofitted with a back pressure turbine.
The steam that is available in fluctuating amounts is used to generate electricity by a single-stage Spilling turbine, before being almost completely re-cooled over an air-cooled condenser. Using the exhaust steam afterwards is at present not possible, however, also its utilisation is intended in the long-term.
