Characterization of biomass producer gas as fuel for stationary gas engines in combined heat and power production (2MB)
Jesper Ahrenfeldt, Danish Technological University, March 2007

Abstract: The aim of this project has been the characterization of biomass producer gas as a fuel for stationary gas engines in heat and power production. More than 3200 hours of gas engine operation, with producer gas as fuel, has been conducted at the biomass gasification combined heat and power (CHP)demonstration and research plant,named “Viking” at the Technical University of Denmark. The plant and engine have been operated continuously and unmanned. Producer gas properties and contaminations have been investigated. No detectable tar content was observed in the gas that goes to the engine; this was confirmed by three different measuring methods. Likewise, no particles were detected in the gas. Considerable amounts of NH3 were measured in the produced gas.An analysis of engine operation at varying load has been carried out. Standard emissions, load and efficiency have been measured at varying operating conditions ranging from 50% to 90% load. Biomass producer gas is an excellent lean burn engine fuel: Operation of a natural aspirated engine has been achieved for 1.2<λ<2.8 without significant reduction of engine efficiency. Relatively high emission of unburned CO was seen at all operating conditions when compared to the current European regulations for CO emissions. The high CO emission from producer gas engine operation is primarily due to the high content of CO in the fuel and is therefore, like UHC emissions from natural gas engines, a measure of fuel passing unburned through the combustion. NOx emissions are in general not a problem for lean burn producer gas operation, except for producer gas with very high concentrations of NH3. Measurements of the emission of polycyclic aromatic hydrocarbons (PAH)showed that there were no detectable PAH in exhaust gas from the engine when it is operated on producer gas. The emissions of aldehydes and laughter gas were measured to be significantly lower for producer gas operation than for natural gas. Analysis of the combustion process for producer gas operation by applying a heat release model showed a constant low level of cyclic variations for a wide range of λ-values. The absence of extreme combustion cycles characterizes producer gas as a good lean burn fuel and indicates that producer gas may be applied in engines with high compression ratio. The engine heads have been removed several times in order to inspect the internal parts for formation of deposits, wear and corrosion, and no significant built up has been seen. Frequent oil analysis has been conducted and no significant degeneration has been seen.

Gasification of Wood Chip Waste for Domestic Heat and Power - January 2009.
Ken Boak, January 30, 2009

Lister

This is my 1953 6hp Lister diesel Startomatic
generator set installed in the renewable energy
workshop. It supplies heated water and power
to my house. Currently it runs on waste veg oil.

The aim is to run this engine using wood gas
produced from woodchip waste from tree
surgery, plus about 20% veg oil in dual fuel
mode.

Engines have been powered on wood gas for
just over 100 years, with main developments in
Europe and Scandinavia occurring during
wartime fuel shortages in the 1940s.

These pages look at my wood gas project.

Video of Honda Accord with GEK driving
Jim Mason, All Power Labs, Berkeley, CA, January 8, 2009

Here's the video of the first drive of the honda with the modified GEK in the trunk. The drive was around oakland and Berkeley California.
http://www.youtube.com/watch?v=8JyazgRBtq8&eurl=http://www.instructables.com/id/Convert_your_Honda_Accord_to_run_on_trash/&feature=player_embedded

Again the point of this side hopper adaptation of the GEK is to get the gasifier into a more horizontal form factor, which better fits in cars, as well as eliminate the drying loads from the combustion zone.

The architecture here uses the waste heat in the output gas to do the drying. The goal is fuel entering the reactor at 0% moisture, then adding it back in as steam via the preheating "air inlets" to the degree the combustion temps allow.

We also entered the honda in a contest on the DIY site, www.Instructables.com, with a pile of craftsman tools as the award.

Tools are good. We all need more of them. So if you would like, please go vote for us, which is also generally a vote for more gasification in the public eye. the instructable is here:

The instructable has a full copy of the GEK gasifier plans and
fabrication/assembly instructions. It also allows downloading them
as a single pdf, which our wiki can't do.
