Bioheat heating plants for Stora Enso in Russia
MW Power has delivered two Bioheat wood-fired heating plants to the Finnish/Swedish paper company Stora Enso for installation in Russia. Their combined heating capacity is 24 MWth.
One plant is located in Impilahti in the Russian region of Karelia. It is equipped with a Bioheat 10 boiler unit.
The other plant is located in Nebolch in the Novgorod region of Russia. It is equipped with two Bioheat boiler units in the same building. One produces 6 MWth and the other 8 MWth heat. Thus the plant has the flexibility to operate on one Bioheat boiler unit if the heat demand is low and both boiler units when the heat demand merits. The provision of two boiler units also ensures continuity of heat supply when one or the other is being serviced. They incorporate patented BioGrate combustion technology to burn biomass fuels with high combustion efficiency and low NOx and CO emissions. The moisture content of the fuel can be as high as 67 %.
Both plants burn wood residue in the form of bark from the Stora Enso sawmills. They provide heating in the form of hot water for the sawmills’s needs. Apart from the economical benefits of burning residue material, the plants have the ecological benefit of using a renewable resource thereby being neutral with respect to carbon emissions and thus global warming.
"An important factor in choosing MW Power as our supplier was their long experience of boiler plant deliveries to Russia. MW Power´s Bioheat plants have the proper certificates and licenses for the Russian market, and we have very good experience from previous cooperation with MW Power as a business partner," says Tapio Särkkä, Project Manager, Stora Enso Timber Oy Ltd.
There are already seven MW Power boiler plants with a combined heating capacity of 52 MWth owned by Stora Enso in Estonia, Latvia and Lithuania.
Vapo Timber Ltd, Hankasalmi sawmill
MW Power has delivered Bioheat heating plant to Finnish company Vapo Timber Oy. The plant is located in company’s Hankasalmi sawmill.
Vapo Timber Oy is one of the largest sawmilling companies in Europe. The company operates four sawmills in Finland: Hankasalmi, Lieksa, Nurmes and Ivalo. The annual production capacity of the four sawmills is 800 000 cubic metres of sawn goods and value-added products. Sixty percent of the production is exported. Vapo Timber Oy is Vapo’s fully owned subsidiary. Vapo Group’s turnover in 2010 was EUR 719,5 million. The Group had 1 333 employees.
Output of the delivered plant is 10 MWth, the contract includes also 6 MWth LFO (light fuel oil) oil plant for reserve use. The plants were delivered as EPC delivery without foundation works. EPC delivery includes building, process units, installation, commissioning and training. Heating plant is fuelled by by-products from the sawmill and peat and it produces hot water for the sawmill´s drying kilns as well as for the premises. The core of the plant is patented BioGrate combustion system, which is developed to produce energy from wet biomass fuels; the moisture content can be as high as 67 %.
BioGrate combustion system is able to burn biomass fuels with high combustion efficiency and low NOx and CO emissions.MW Power’s good relationship with the customer and as well as reliable and highly advanced solution based on customer needs were amongst the reasons Vapo Timber Oy chose MW Power to deliver the plant to Hankasalmi. MW Power also offers service concept through-out the plant´s life cycle.
Sangla Turvas SA, Puhja, Estonia
MW Power has delivered Bioheat boiler plant to Sanglas Turvas SA in Puhja, Estonia, to generate six tonnes per hour of steam for heating the driers in a plant producing fuel briquettes from peat. The Bioheat boiler thus has a capacity of 4 MWth. It will burn a mixture of 75% milled peat and 25% wood chips. However, it will be able to burn milled peat alone, and will be the first Bioheat boiler with this capability. Sangla Turvas Ltd. is operating in Puhja, Tartumaa, and its main fields of operation are producing peats, peat briquet and energy.
The plant incorporates patented BioGrate combustion technology to burn biomass fuels with high combustion efficiency and low NOx and CO emissions. They are thus practical solutions for the need for renewable energy supplies with minimum environmental impact.
