Uniconfort Biomass Gasifier Installation

Submitted by Erin Rasmussen on

Here, a Uniconfort gasifier is installed within an industrial application. Note the fuel feeding system visible at the right hand portion of the photo. Also, note the absence of a smoke plume, even though the gasifier is running at full load. Emission reductions are a large advantage of gasification over traditional incineration.

Spilling Steam Piston Engine

Submitted by biolists on

This photo features a Spilling Piston Steam powered engine. The Spilling engine is a durable, proven alternative to steam or gas turbines- best known for its durability and performance in remote applications. These engines are utilized to generate electricity from biomass when paired with solid fuel steam boiler technology. To find out more

The attached diagram which shows the relationship of all fuels to their C-H-O content. I first developed this at SERI/NREL ~1980 and have been refining it ever since. It seems to draw a lot of chemistry together and make it understandable for the chemistry no-wanabes.

India: Gasification of bamboo for electricity

Submitted by Tom Miles on

Gasification of bamboo for electricity

Government of India, Ministry of Science and Technology, DEPARTMENT OF SCIENCE AND TECHNOLOGY (DST) 2007

NMBA, National Mission on Bamboo Applications http://www.bambootech.org

DST/ NMBA has approved the establishment of a 25 Kwe fabricated
gasifier with producer gas engine at Namsai, Lohit district.

DST/ NMBA has approved the establishment of a 25 Kwe (35 kg/
hour) gasifier to provide electricity for a residential educational
establishment (Central Institute of Himalayan Culture Studies,
Dahung) in Arunachal Pradesh.
DST/ NMBA will support, for off-grid and remote villages,
a programme of induction of 6 bamboo gasifiers in 2007 (in
the 25 Kwe - 75 Kwe range), to provide electricity to villages,
or to institutions (residential schools, health sub-centres,
small enterprises).

Engine Tables
Doug Williams and Dr. Oscar L. Jimenez, October 2007

When the original Fluidyne Engine Tables were compiled by Jack Humphries back about 1978-9, they were to provide the user with a guide, as to how the engines at that time performed on Producer Gas. It simplified the mass of calculations that required inputs not readily available to those investigating engine powered generation, and as such, have proven to be reliable to this very day.

Charcoal Gasifier No. 4: Operating the Charcoal Gasifier

Submitted by Visitor (not verified) on

Doug Williams, Fluidyne, New Zealand, August 13, 2007

Hi Gasification Colleagues,

This posting is about operating the charcoal gasifier, and how to start the process. It will be important to remember, that even charcoal gasifiers are fuel specific, and as a rule of thumb, the smaller the gasifier, the smaller the fuel (within reason). The charcoal should be sieved, and I suggest that nothing under 20mm be used until you establish the optimum size for the type of wood the charcoal is made from.
Your gasifier should have a single air nozzle with a screw cap for shut-down on the outside end, a gas outlet, and a lid with a heat proof seal, which is a gasifier in the most basic format. If you decide to make one with a grate, then you will also have to include a gas clean-out port in the bottom.
