BioEnergy Lists: Gasifiers & Gasification

Wes Tyler at Icy Straits Lumber, Tom Miles, and Jim Mason with All Power Labs, Alaska, 2012

In Alaska, there are a lot of remote villages that generate electricity by using small oil generators. But, transport costs and fuel costs have made the electricity very expensive, and the costs of heating their homes and generating electricity has been a burden on the businesses and families in the rural areas.

Icy Straits Lumber, in Hoonah, Alaska is testing a small All Power Labs Gasifier at their lumber mill. They have a ready supply of the right kind of fuel, have staff familiar with this type of equipment, and need some extra power, that's less expensive than the imported fuel they'd normally be using. This will be a good place to see if this type of gasifier will work well in the winters in Alaska, and if so, it may be recommended to other communities.

BTG Biomass Technology Group in the Netherlands has released a fully updated version of their useful
Handbook Biomass Gasification

This is a fully updated and expanded successor of the first handbook which was issued in 2005.

This fully updated and expanded Handbook of Biomass Gasification reviews the current state of technology and describe the latest success stories. Compared with the first edition, it not only contains updates of topics covered earlier, but also several new chapters which we trust will be of interest to the biomass gasification community. The Handbook aims to guide newcomers as well as persons that are already familiar with and/or involved in biomass gasification, be it as researchers and technology developers, policy developers, investors, end-users and/or other decision makers.

Drying seeds is a major concern fro growers in Nueva Ecija, especially when harvesting coincides with rainy periods (that make sun drying seeds difficult). Rice Husks can make an inexpensive fuel, and a Rice Husk Gasifier is an improvement over the traditional Furnace Design

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.

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.

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:
