Flen heating plant, Sweden

Flen heating plant, Sweden

Background:

The district heating production in Flen started in the early 2000s and is operated by Solör Bioenergi Fjärrvärme AB. The plant consists of two biofuel boilers where mainly sawdust, wood chips and bark from the local area are burned. Solör Bioenergi aims to take advantage of the forest’s resources and contribute to a sustainable society with reduced carbon dioxide emissions, which together with reduced energy costs has justified an investment in an ORC turbine. Solör Bioenergi has previously invested in ORC turbines for the heating plants in Hörby, Svenljunga and Vilhelmina.

Our solution:
Againity delivered an automated ORC system with a maximum capacity of 99,9 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 519 MWh electricity annually, corresponding to annual emission savings of 467 tonnes of CO2 equivalents when substituting coal-based electricity.
