Finnish Power Plant Orders Biomass-Fired Boiler
A power plant in Tampere, Finland, ordered a biomass-fired boiler to replace an existing boiler that reached the end of its technical lifetime. Valmet will deliver a boiler plant utilizing circulating fluidized bed (CFB) technology by the end of 2022. The delivery extends from the boiler silos to the existing flue gas heat recovery system.
The boiler plant will be fueled mainly by renewable biomasses, while milled peat will remain as a secondary fuel. With a steam capacity of 191 MW, it will run as a base load plant for district heat production from September to June. The concept is based on combined heat and power (CHP) production, and it uses the existing old steam turbine and its auxiliary systems. The total efficiency ratio of the new plant is about 112 percent based on the fuel’s effective heating value.
Tampereen Sähkölaitos says its goal is a 95 percent decrease in emissions by the end of 2030.
