Valmet will deliver a boiler plant that utilizes biomass to Nokianvirran Energia in Finland. Valmet announced the signing of a letter of intent for the delivery on November 25, 2014. Valmet's delivery will include a HYBEX boiler with a steam power of 68 megawatts (MW) that employs the fluidized bed technology, flue gas purification equipment, and the plant's electrification and automation system.
The boiler plant will be delivered for a new steam heat station to be built in Nokia. The total value of Nokianvirran Energia's investment is approximately EUR 45 million, of which the value of Valmet's delivery is slightly more than a half. The order is included in Valmet's first quarter 2015 orders received.
The new heating station will produce process steam for the SCA Hygiene Products paper mill and the Nokian Renkaat factory, as well as district heat for Leppäkosken Lämpö's district heat customers. The fossil natural gas previously used for energy production will be replaced with more affordable biofuels, such as timber chips and whole tree chips. In addition, the boiler can utilize milled peat and sludge from the paper mill.
Leppäkosken Lämpö distributes the district heat produced by the power plant to its customers through its network. "This investment will especially improve the price competitiveness of district heat compared with other heating methods," says Juha Koskinen, the managing director of Leppäkosken Lämpö.
For SCA, which manufactures tissue, the investment will decrease the company's dependence on fossil natural gas. In addition the de-inking sludge derived from the tissue mill can also be used for energy production at the new power plant.
For Nokian Renkaat, the power plant will bring cost benefits, and additionally reduces the greenhouse gas emissions of the production process.
Nokianvirran Energia Oy's current plant consists of two gas-fired boilers with a steam power of 57 and 110 MW. The new 68 MW plant to be constructed will be integrated with the existing power plant. As gas is replaced by biofuels, carbon dioxide emissions in the area will decrease by 60,000-80,000 tons per year.
