Finland's largest pellet-fired heating plant, which was supplied by Metso to Tampereen Energiantuotanto Oy, Tampere, is employing a technology that is said to be the first of its kind in the country. The plant has been producing energy in Tampere since last December.

Tampereen Energiantuotanto, part of Tampere Power Utility, is responsible for the group's electricity and district heating production, maintenance and development.

The company's plant is mainly fired with wood pellets and its heat output is around 33 MW. The plant has replaced some of the capacity of the oil- and gas-fired boiler plants and has thus helped substantially reduce the CO2 emissions from the production of district heat.

"The plant will help us to secure the competitiveness of district heat, lower CO2 emissions and improve our delivery reliability in the southern region of Tampere," said Antti-Jussi Halminen MD of Tampereen Energiantuotanto.

Metso's delivery comprised a complete turnkey boiler plant solution and its DNA automation system. The new plant operates unmanned with remote monitoring from the main control room of the Lielahti power plant.

By using the automation technology, the operators are able to flexibly control the district heat production process and quickly respond to changes. The technology used at the plant is based on the pellet fuel being pulverized in separate grinding mills and burned in a pulverized combustion boiler.

The start-up and load control of the combustion process is remarkably high and the pulverized fuel allows for clean, energy efficient and flexible heat generation.

Pulverised pellet combustion is new to Finland, but Metso has been using it in Sweden on a smaller scale.

This was a major delivery for Metso, as it is the first reference using this technology for district heat generation on such a large scale, said says Jussi Orhanen, director, heat & power plants, part of Metso's power business unit.

The Bioheat RampUp plant delivered by us enables the use of pellets and oil, simultaneously in any proportion or separately, in one and the same boiler, which is operated unmanned."
