Metso carbon dioxide monitor for Finnish CHP plant

A carbon dioxide (CO2) measurement system at the Martinlaakso 1 combined heat and power plant (pictured) run by Vantaan Energia in Vantaa, Finland, has been approved by the Finnish Energy Authority - the national administrator for the EU Emissions Trading Registry.

The reporting application, from Metso, enables measurement-based CO2 monitoring for emissions trading purposes and is a first for Finland, company says. Commissioned at the coal-fired Martinlaakso power plant in 2013, in addition to Metso system suppliers included SICK, which delivered the online measuring equipment, and Indmeas, which supplied the flow measurement.

Martinlaakso produces about two-thirds of Vantaa Energy's electricity output and most of its district heat. The total capacity of the plant is about 195 MWe and 330 MWth.

‘Before installing the system, this emission information was obtained by sampling and weighing the incoming fuel,’ says Samuli Björkbacka, Operations Engineer, Vantaan Energia. ‘The information provided by the new application is used in our process calculations and in verifying the plant's CO2 emissions for the authorities. Online monitoring also allows the operators to immediately see possible measurement malfunctions.’
