Biomass Technologies Thermal Energy and CHP
Central Washington Biomass Energy Workshop Ellensburg, Washington Andrew Haden April 2015
What is Biomass? Forestry residuals and “clean green” wood waste: wood from tree trunks and branches, chipped Compressed wood, pellets, bricks: untreated wood with limited bark content, compressed by machine Mill residuals: a mixture of untreated and treated wood in form of shavings, chips, sawdust Construction waste: untreated wood that has been used in commerce prior to its energetic utilization
Ag fuels: straw, grasses, corn stover, purpose-grown feedstocks Modified from Viessmann Manufacturing
Biomass Heat and CHP • Efficient: modern heating and CHP systems have high conversion efficiency (>85%) • Clean: modern biomass CHP systems have very low particulate, NOx and CO emissions • Economical: cost effective, fuel prices lower than oil, propane and electricity • Sustainable: CO2 neutral, regionally abundant, compliments sustainable forestry
