Finland Power Plant Getting Metso HRSG

Posted on July 6, 2011

Metso will supply Vantaan Energia Ltd with a heat recovery steam generator (HRSG) including main accessories, installation and commissioning. The 56 MWth boiler will be delivered by MW Power, the Metso-Wärtsilä joint venture, and be installed into a US$21.4 million (€15 million) new waste-to-energy plant in Långmossebergen in the city of Vantaa, Finland.

In Vantaa Energia’s new plant, the waste will consists of two combustion lines and an integrated gas turbine and heat recovery steam generator (HRSG) and steam turbine. The heat recovery boiler is designed to increase the overall efficiency of the power plant, Metso said.

The HRSG recovers the excess heat from the gas turbine’s flue gases. Its main role is to produce superheated steam for the steam turbine and low pressure auxiliary steam for the process as well as district heat. The heat recovery boiler not only produces its own steam, but also superheats the steam from the two waste incinerators.
