Metso has signed several contracts for supplying automation technology for greenfield waste-to-energy plants in Italy, Estonia and the UK. Modern automation solutions will play a major role in managing these new plants successfully. Plant operators will able to maximize incineration capacity, keep combustion and steam production stable, as well as maintain high process availability. Extensive, employee-empowering automation will ensure that waste burns safely and emissions stay low.

Metso has extensive experience in supplying automation and information management applications to waste-to-energy plants that run on industrial, municipal and wood waste or sludge. The company has a long track record of deliveries to roughly a hundred waste-to-energy and biomass combustion plants around the world. .

CNIM chooses Metso’s automation for greenfield waste-to-energy plants in Italy, Estonia and the UK

Metso has recently received three orders for Metso DNA automation systems for greenfield waste-to-energy plants from the CNIM Group. The latest order is for the North Hykeham plant in Lincolnshire, UK. It was preceded earlier this year by similar orders for waste-to-energy plants in Turin, Italy, and Maardu, Estonia. CNIM, the European leader in construction of waste-to-energy plants, acts as a contractor in all these projects.

At these plants, Metso DNA will provide one system for all process controls and plant information management. The integrated process automation system covers all plant processes from boilers to turbines. High-level reliability is ensured through an integrated TUV certified safety solution.

The North Hykeham waste-to-energy plant is owned by the Lincolnshire County Council and will be operated by the Waste Recycling Group. It will have an electric output of 13.1 MWe and a thermal output option up to 10 MWth. With an annual capacity of 150,000 tons of household and similar waste, and it will provide electricity to around 15,000 houses and the national grid. The plant is scheduled to go on line in spring 2013.

The Turin waste-to-energy plant owned by Trattamento Rifiuti Metropolitani will have a thermal output of 206 MW and an electric output of 56 MWe. It will be able to handle 421,000 tons of household and similar waste annually, with three incineration lines and provide electricity to around 150,000 houses and district heating to about 17,000 houses. The plant will go on line 2013.

The waste-to-energy plant in Maardu, owned by Eesti Energia, will have a thermal output of 50 MW and an electric output 17 MW. Using up to 220,000 tons of municipal, industrial and construction waste annually it will supply district heating to 500,000 inhabitants. The plant will go on stream in 2013.

Established in 15 countries, the CNIM Group designs and produces turnkey industrial solutions and offers expert research, expertise and operations services in the fields of environment, energy, defense and industry. The group has 3,000 employees, and its turnover was 633 million euros in 2010.

Hitachi Zosen Inova AG goes for Metso DNA to fulfill customer requirements in the UK

Metso has also signed an agreement with Hitachi Zosen Inova AG to supply automation for two lines at a greenfield waste-to-energy plant being built by SITA South Tyne and Wear Ltd. in Tees Valley, Billingham, UK.

The waste-to-energy lines under construction at the North East Energy Recovery Centre will each have the capacity to incinerate 152,000 tons of waste per year. They will feature grate-fired boilers with a thermal performance of 2 x 45.85 MW and rated turbine capacity of 24.2 MW with a live steam temperature of 410°C. The plant will start commercial operation in the autumn of 2013.

Metso’s delivery scope consists of a Metso DNA distributed control system, a Metso DNA information management system, on-site commissioning, trial run support, training and spare parts. To boost system availability, there will be a remote service connection between the plant and Metso. Metso’s delivery will take place in September 2012.

With advanced solutions, the operators will be able to manage operations and information efficiently at the plant. The system includes, DNA Report, an umbrella application for all Metso DNA reporting and analyzing tools, and solutions that use historical data stored in the DNA Historian database. It includes tools for report development, calculations, trending, alarms & events analysis, manual data entry and an operator log book. One example of the tools is Tracer, a process history analyzing tool combining traditional trends with alarms and events in the same graphic with a common timeline.

Metso was chosen as the supplier for the plant based on its good track record from five earlier projects with Hitachi Zosen Inova at A.S.A. Zistersdorf in Austria, BIR Bergen in Norway; Riverside and Newhaven in the UK and Vaasa in Finland.

“Compared with other systems in use in our previous projects, we immediately understood that Metso DNA is a flexible, state-of-the-art and easy-to-operate system.
