Charcoal Gasifier No. 4: Operating the Charcoal Gasifier

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.

Ultimate test for Producer Gas

Ultimate test for Producer Gas
Doug Williams, Fluidyne Gasification, New Zealand, August 5, 2007

Gasification Colleagues,

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.

GAS-L: Re: pressurized combustion

Aerts, Parker et al:

I found the following on my laptop three weeks after I got home, probably
written in the Tokyo airport during my "extra" Saturday, courtesy of the
dateline.. If I sent it before, please excuse!

On my trip I saw a monstrous pressurized recirculating fluidized bed combustor
in Finland. It was impressive as a major engineering feat. One justification
is that the hot gas filtering with ceramic candles are relatively cheaper at
high pressure. However, the cost of the equipment is very high for combustion.
