Inray delivers a real-time fuel quality measurement system for the Vantaa Energy Martinlaakso power plant, where the old boiler is modified into biofuels. The new biopower plant uses primarily as a fuel wood chips, forest residues, sawdust and residues from plywood industry. The system provided by Inray automates the fuel quality determination of the plant. The system will be implemented in winter 2018-2019.
