Hitachi Zosen Inova wins EUR60 million order for DE plant

Finnish energy company Vantaan Energia has contracted Hitachi Zosen Inova to deliver the combustion boiler to the new combined cycle district energy (DE) plant serving the Helsinki area.

Replacing a former coal-powered plant, the new EUR60 million (US$87 million) Vaanta plant will reduce coal consumption by some 30%.

The plant will be fueled exclusively by municipal solid waste from the Helsinki metropolitan area - the cities of Helsinki, Vantaa and Espoo - reducing carbon dioxide emissions by up to 130,000 tonnes per annum.

The new facility, slated to begin operation in July 2014, consists of two waste-to-energy- units with a capacity of 64 MW each and a nominal annual throughput of 352,000 tonnes of municipal solid waste.

Steam derived from the municipal solid waste fired boilers will be overheated to 520 °C using exhaust from a gas turbine for combined power and heat production.

The maximal output of the combined facility will amount to 78 MW electrical and 107 MW thermal – approximately a 7 MW higher power production compared to a solution with two individual facilities.

The heat production will correspond to about half of Vantaa's annual heat requirement.
