Metso will convert the combustion technology at the Haapaniemi 2 power plant of Kuopion Energia in Kuopio, Finland, from pulverized peat-fired combustion to fluidized bed technology. The project scope includes all modifications in the boiler required by fluidized bed technology such those in the pressure vessels; new air, ash and fuel systems inside the boiler house; and new superheaters and economizer. The rebuild will be carried out during the summer and early autumn of 2013. The value of the order will not be disclosed.

The project is intended to decrease the power plant’s emissions because the European Union’s Industrial Emissions Directive will tighten the emission requirements for power boilers by the beginning of 2016. After the conversion, the plant will use practically no heavy fuel oil and also have lower fuel costs. In the future, the boiler will run on peat and wood with a mixing ratio that can be varied flexibly.

“This conversion will make us less dependent on energy peat that has suffered from delivery problems. It will also enable us to maintain the competitiveness of district heating in the future. The project makes it possible to significantly decrease CO<SUB>2</SUB> emissions and is thus in line with the Climate Policy of the City of Kuopio,” says Esa Lindholm, managing director at Kuopion Energia.
