Creating Combined Heat and Power from Biomass Gasification in Skive, Denmark

Andritz continued development of the GTI Energy gasification process for biomass applications and has a commercial project in Skive, Denmark providing 12 MWth of district heat and 6 MW of electric power using wood pellets as the fuel. This combined heat and power project completed has been in operation since 2009. A single fluidized bed gasifier provides fuel gas for three reciprocating engine generating sets (2 MW each), from which the heat is recovered for the community's district heating needs. Gasification enables the facility to produce about 30% more electricity than a conventional steam process. Two gas boilers in the facility can also use produced gases to meet additional district heating demand. The overall process efficiency in this combined heat and power operation is about 90%.
