Valmet handed over a new biomass boiler and flue gas treatment for RWE Innogy UK's Markinch combined heat and power plant (CHP) following a commissioning period and test-runs. The plant is located in Fife Scotland, and is reportedly the largest of its type in the United Kingdom.
The new plant provides the Tullis Russell Papermakers with steam and electricity to run the facilities. In addition, excess electricity is exported to the grid. The energy provided by the CHP plant helps Tullis Russell to reduce its fossil fuel emissions and significantly contributes to Scotland's renewable energy targets. Replacing the paper mill's 60-year-old coal-fired plant with this new biomass-fired plant reduces CO2 emissions by 250,000 tonnes per annum. The main fuel for the CYMIC boiler is recovered waste wood, so the amount of waste wood that ends up in the landfill is expected to drecrease.
The new biomass boiler provides the Tullis Russell paper mill with a more sustainable, efficient and reliable supply of steam and electricity. The CHP plant's installed capacity is 50 MWe. It has the capability to supply up to 120 tonnes of industrial steam per hour for paper manufacturing. Out of the produced electricity the paper mill will consume approximately 17 MW and approximately 25 MW will be delivered to the grid.
The plant has been in commercial operation since February 2014 with full handover of plant in late 2014.
