Heat recovery from engine testing: Thermal energy for the city of Turku

Wärtsilä NSD Corporation Press release 3 March 2000

Wärtsilä NSD is modernizing its engine test running system at Wärtsilä NSD Finland Oy’s Turku Factory. The new system will incorporate an electric engine loading system based on generator technology. This will convert the energy produced during engine test runs into thermal energy which will be used to heat the factory and also fed to Turku Energia’s district heating network for the needs of the local community. The factory’s existing system allows only a fraction of the energy produced by engine testing to be used for factory heating.

The project will contribute to reducing atmospheric emissions in the Turku region. The recovered energy will reduce Turku Energia’s heat production requirement and therefore its emissions into the atmosphere. The recovered and recycled energy will roughly equal the amount of thermal energy needed annually to heat one thousand homes.

The Turku Factory test runs all the engines it manufactures. Engine testing is a condition stipulated by customers as they wish to obtain assurance of the product’s quality at the factory. Engine testing involves testing and measuring the engine’s performance and functionality in the presence of the customer or his representative. Recovery and reuse of the energy generated during testing will start in stages. The first stage will be completed by the end of the current year.
