Metso will supply Vantaan Energia Ltd with a heat recovery steam generator (HRSG) including main accessories, installation and commissioning in a deal worth almost EUR15 million (US$21 million).

The boiler will be delivered by the Metso-Wartsila joint venture, MW Power, and will be installed into a new waste-to-energy (WtE) plant in Långmossebergen in the city of Vantaa, Finland.

The project is scheduled for completion in 2014.

The heat recovery boiler MW Power is delivering will increase the overall efficiency of the power plant.

The HRSG recovers the excess heat from the gas turbine’s flue gases and 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, which increases the overall efficiency of the power plant.
