Hallingdal

Hallingdal is a Norwegian Waste-to-Energy plant, built in 1985, burning household waste on one line of a 3.5 ton/hour capacity and equipped with a Volund grate.

The FuzEvent Installation
The project was completed in 2005 and has since then been inprooved further and now in 2009 still in operation with very high efficiency.  
The FuzEvent installation provided the following results:

• CO emissions within EU limits,
• 10% more throughput,
• 100% automatic control, no set-points adjustments by the operators.

The DD-Jet Installation
The project was successfully completed in August 2008. 4 nozzle injection holes were prepared in the boiler roof in order to clean the boiler at a rate of 15 minutes twice a week.
The DD-Jet installation provided a reduction of the flue gas temperature at the economizer by 120°C, which allows the plant to burn more waste.

The Service Contract
In order to achieve a continuous optimization of the plant by the FuzEvent system, the Hallingdal plant has subscribed to a Service Contract since 2008 for long-term partnership.
Services included in the contract:

• Engineering assistance per year by remote service, internet logon, or visits at the plant;
• Identification of cause of operation related optimization problems;
• Remedy of operating trouble related to process optimization and mechanical areas;
• Installation of new versions of the FuzEvent software;
• Introduction to the functions of the FuzEvent system to the operational staff of the plant in connection with plant visits.
