Danish Technological University Updraft Gasifier Plant

DTU Updraft Gasifier and Stirling Engine
Today, operation started on Stirling DK's latest installation situated on the campus areas of the Technical University of Denmark (DTU). Approximately 1% of DTU's total power consumption and 2% of its heat consumption will be supplied by the installation.
The plant includes a Stirling engine with an output of 35 kWe of electrical power. The surplus heat from the plant, in the form of hot water, is fed into the district heating system of the DTU campus.
The plant is fuelled by wood chips originationg partly from cuttings from DTU park areas. In this way, the plant is a stand-alone facility that enables DTU to become partly self-sufficient with CO2-neutral power and heat from locally availabel fuel sources.
More information about the project can be found here.

GEK and Burner
Frank Shields demonstrated Jim Mason's Gasifier Experimenter's Kit (GEK) at the ETHOS 2008 Stoves Camp in Cottage Grove, Oregon, August 5-9, 2008. Frank gave the gasifier it's first trials at the Stoves Camp which is held annually at Aprovecho Research Center to train people in making improved cooking stoves for developing countries.(See Biomass Cooking Stoves http://www.bioenergylists.org)
Ultimate test for Producer Gas
Doug Williams, Fluidyne Gasification, New Zealand, August 5, 2007
Since I began working with producer gas in 1976, the question of it's quality, and how to measure it in a way that clarifies it's purity, has never in my mind, been answered by gas analysis. I have seen many gas analysis presented to prove a gasifiers function, and therefore justify claims of how this gas can be used, but this can hide a multitude of problems within the gas making phenomena.
