By Erin Voegele | September 04, 2019

Valmet announced Sept. 2 it will supply a biomass-fired boiler and a flue gas treatment plant to BS Energy’s combined-heat-and-power (CHP) plant in Braunschweig, Germany. The biomass-fired CHP plant will produce approximately 20 megawatts (MW) of electricity and 60 MW of thermal energy for use in district heating.

According to Valemet, the CYMIC circulating fluidized bed boiler included in the delivery will use recycled wood as its primary fuel. The boiler generates 27 kg/s of high-pressure steam at a pressure of 75 bar and a temperature of 525 degrees Celsius. Its steam-generating capacity is 78 MWth.

The fuel gas cleaning system included in the delivery will enable the facility to fulfill future tightened emissions standards with the help of a two-phase dust removal system and a semi-dry sorbent injection system.

The biomass boiler will replace the facility’s existing coal-fired boiler. The biomass-fired CHP system is expected to begin operations in early 2022.
