The CBEND project in Namibia, Generating power from the Invader Bush.

Invader Bush, is a tall thorny bush that has large spikes that often harm the local wildlife trying to walk through the savannah. CBEND has already been successful at chopping the bush and processing it into a form that the people there can use as fuel in their stoves and ovens. This provides some money to pay for the plant operations and help the cheetah. By adding the gasifier, CBEND also generates electricity, and increases it's capacity to dispose of the chopped up invader bush (which is primarily a woody shrub).

CBEND posted some photos the gasifier and of the processing equipment

And several reports and publications about the project

Avani is an NGO in the Central Himalayan Region of Uttarakhand, India. They are launching a program to provide electricity, cooking fuel, and jobs to remote mountainous villages through their pine needle gasification program. In the next five years, they will put up 20 village-level pine needle gasifier system to provide 2.4 MW of electricity, cooking fuel to 250,000 people, and 2,000 local jobs.

Eco Market Solutions, Philippians

Governer Bella Angara-Catillo, Mayor Tubigan and the Dinalugan Municipal Council are proud to cut the ribbon on the first gasifier for rural power electrification in the Philippines this month.

The 250kw Gasifier is welcomed by the community of Dinalungan, Aurora as an alternative to expensive diesel power in the area. Diesel power in the local communities are struggling to provide power for more than 6 hours per day.

The plant is run by Eco Market Solutions (related to the wind power company Greenworld Wind Power). The gasifier is using running on wood, coconut fronds and coconut shells. In May they plan to use biomass briquettes made from rice straw, rice and coconut husks, corn cobs and dried grasses, which they expect to purchase from local farmers. Currently they use about 8 tons of biomass a day when they are running at full capacity.

See the attached press release for more details.

Taim Weser, Spain, 2011

Starting in 2010, Taim Weser installe their own Downdraft Biomass Gasifier in one of their Steelworking and Machine shops to use more renewable energy, and reduce their reliance on the gas they had been using to heat their shops. In addition to using the gas produced by the gasifier, they also recovered heat for use in their facility, and they estimate that the payback on their investment will be realized (without subsidies) in less than 2 years.

These are some brief specs from their website about their gasifier:

Characteristics of the system

• Biomass consumption: 650-750 kg/h
• P.C.I. synthesis gas: 1.32-1.55 KWh/Nm3
• Gas flow in Engine: 1.170-1470 Nm3/h
• Ashes: 15-35 Kg/h

Technical specifications

• Electric power: 650-750 KWe
• Useable thermal energy: 1200-1400 KWt
• Plant consumption (without biomass preparation): 10%
• Operating time: 7000 h/year

Representatives from Taim Weser summarized their project in a presentation for the German waste to energy + recycling conference in May, 2011

Larry Dobson, December, 2011

For the plans and other detail of this gasifier/water heater check see Larry Dobson's web site:
http://www.fundamentalform.com/html/biomass_gasifier_breakthrough.html

Larry has been working on gasifiers for more than 30 years. His other work has been of a more traditional design. This idea is a home water heater with a high efficiency and a good turn down ration 20/1 and the ability to use high moisture fuels - provided that they are properly sized and fed. This has a manual design, it is still a prototype, but there is room for electric control and other improvements.

These are some of the highlights (quoted from Larry's web site):

"THIS GASIFIER/FURNACE IS DESIGNED AROUND THESE CONSIDERATIONS, WITH THE FOLLOWING FEATURES:

• The hopper and entire construction is cylindrical, creating more even feed and flow, less thermal stress, simpler construction, more reliable seals, thus the name “Roundy”.
• When burning the gas to heat water, the generated gas is burned in a concentric combustion shell, which feeds heat to the incoming air and fuel in the hopper, augmenting the calorific value of the produced gas, thereby requiring less air for more gasification of a higher quality gas, which is mixed with preheated air and burns super-clean in the combustion shell.
• Highly preheated gasification air is introduced to the preheated fuel around the base of the hopper, where it is burned and gasified, creating a steady-state fuel feed without disruption of the fuel. Residence time of all heat transfer and chemical reactions can be much greater than conventional practices, which greatly expands fuel options.
• Any fuel that will fit in the hopper and produce a combustible gas can be gasified ~ logs, chips from the tree trimmers, bark, sawdust, corn cobs, leaves, wood-, straw-, municipal solid waste-pellets, green and wet biomass (up to 2/3 water), household and farm waste, etc. Since this first version of the gasifier has a thin-shelled ceramic hopper lining, large heavy chunks of fuel should not be dropped in, especially without a cushioning coal-bed. Testing of this prototype will indicate whether a lighter, thinner stainless steel hopper will withstand the internal temperatures.
• Although this design with all the interrelated heat-feedback features is where I want to begin testing, you may wish to begin with a simpler version. Many variations and degree of refinement are possible, beginning with a simple insulated inner shell and moving conical grate configuration, or reducing the size of the heat-exchanger or air preheater. However, adding air-preheating and gas-cooling shells will substantially improve performance.
• This is no longer a patentable design, as I hereby release it to the public domain, in the hopes that others will implement these new design features and do the R&D work necessary to bring biomass gasification to a new level of practicality, offering a greater contribution to decentralized alternative energy technologies.
• This first prototype is experimental, with no guarantees, although past experience and flow analysis says it should work great. It is not a simple vehicle-size unit made from scrap metal from the junk yard, although those and other options should be explored by you backyard tinkerers. I have designed it to test several new concepts that could be the foundation for a new approach to gasification.

Mobile pyrolysis plant is designed not only to produce charcoal, but also for the production of birch tar from birch bark, automotive recycling tires into liquid fuel. As we know the demand for charcoal depends on the season. In the spring and summer of charcoal taken better in winter, worse. Birch tar is always in demand, but in small quantities. His take veterinary hospitals, pharmacies, some enterprises Chemical Industry. On tire recycling products is a constant demand for steel cord, coke (with a mixture of soot). For liquid heating oil needs a constant source of sales. In addition, the tires are not always in large quantities.and for their storage needs more space. Due to the versatility you can optimally allocate mode setting so that it is not idle, and there was a constant sales.
In the production of charcoal in the mobile uglevyzhigatelnyh facilities for people working in them, you have to manually unload the charcoal, wood dust to breathe, which affects their health.
Mobile uglevyzhigatelnye installation with a few exceptions, much smoke, emit dymogazy, which contains a number of not dogorevshih combustibles.

The most advanced facilities at the lower emission of harmful substances into the atmosphere from stationary pyrolysis systems NRM Polikor, Ekolon. The process of charcoal production is mechanized.
Of mobile pyrolysis plants can be noted uglevyzhigatelnyh pyrolysis furnace uglevyzhigatelnuyu MUL2S, but it is necessary to exit the charcoal by hand. You also need time to cool down the furnace.

Proposed for the production of pyrolysis for charcoal burning mobile unit consists of several sections hoppers (retorts).Bunkers are closed tightly. They are mounted on hinges and can be rotated in a vertical plane. So, if you want to unload the charcoal ready, simply turn the tank and hold it in front of the bunker-settler. Next, open the door in the side hopper and charcoal thrown out himself in the bunker-settler. Then, the charcoal in a bunker-sump cover asbotkanyu to spontaneous combustion of coal was not. Just a few minutes and the hopper is ready for the next boot .. And load it as follows: hand winch or two people turn the hopper (retort) in the vertical plane to the horizontal position and lock in this position, putting on scarves, a hopper tube. Next, you can start loading firewood or tires, processed tires if for the production of liquid fuels. I note that the processing of tires need additional equipment for the condensation of combustible gases and liquid filtration otopliva.

In the mobile pyrolysis unit best burn combustible gases. Saving wood combustion in the combustion chamber reaches up to 25%. In addition, in the process of heating boilers and carbonation involves pyrolysis gases leaving when shrinkage drevesiny.Na bins installed three-way valves. When an intense parovydelenie, steam is expelled through a three-way valve.

The process of starting the boiler in the following: first, melted wood in the firebox, and then the boiler works and heats the hopper combustion of pyrolysis gases coming out one by one with each bin. For the afterburner pyrogas provides secondary air supply to the nozzle located below the combustion chamber.

The design of the installation is designed so that you can get close to any location and make repairs in places most high-temperature steel sheets are replaced by chamotte plate. All heat-stressed place of the combustion chamber are thermally insulated. Steel structures are not subject to deformation.

Details of the construction of this facility is described in etogm site:

produce engine grade fuel.

The question on everyone’s mind is:

“How can I make my machine produce engine grade gas for decent periods of time?”

Several people have had partial success so far. I (we) know that this device isn’t an imbert style machine, but we who have them do want to see how far they can be pushed.
To that end:
I have been accumulating correspondence between myself and about 15 other users/interested parties since June of this year.
-Many questions have been asked and answered.
-Several members have been reporting test results
-Several members have been making changes and modifications to the machines and the process.

These messages are simply arranged (roughly) by date, by correspondent, newest entry first, on the following webpage:

http://www.spaco.org/Woodgas/JXQ-10forum.htm

If you are a user of one of these machines (or are seriously interested in getting one), and have some input or some serious questions, please check out that page and give us input as you see fit.

NOTE: Senior members of this list are unlikely to gain any new knowledge by visiting this page.---- yet, anyway.
