The boiler with its auxiliary equipment will be part of BS Energy’s energy production strategy 2030. The primary target of the investment is to replace the coal-fired boiler, which will be removed from production in 2022. In addition, the new biomass-fired CHP plant will support BS Energy's objective of environmentally friendly and carbon-neutral production, as it will serve as a base-load unit to meet the district heating and electric power needs of the Braunschweig municipality.
"Valmet’s circulating fluidized bed technology provides reliable operation for waste wood and various other challenging biomass fuels. This plant will fulfill future environmental demands with low emission levels and high efficiency on electrical and district heating production," said Kai Janhunen, Vice President of Valmet's Energy business unit.
The biomass-fired CHP plant will produce approximately 20 MW of electricity and 60 MW thermal of district heat. The takeover of the biomass-fired CHP plant is scheduled for early 2022.
The CYMIC circulating fluidized bed boiler included in Valmet's delivery will use recycled wood as its primary fuels. The boiler generates 27 kg/s of high-pressure steam at a pressure of 75 bar and a temperature of 525°C. Its steam-generating capacity is 78 MWth.
