Charcoal Gasifier No. 3
Doug Williams, Fluidyne, New Zealand, July 28, 2007

Hi Gasification Colleagues,

It is clear from the private mail coming to me, that charcoal gasification has created an interest that allows many to now enter these discussions. While my emphasis is to try and make it understandable for beginners, it should also stimulate those more advanced to test what I say against their own experiences,( such as Ken Calvert has provided). His real DIY experiences show that you can get going if you have some help to start. I really do not like to ignore or delete mail asking questions, but please wait until the end of these informal lessons, to initiate questions and answers. If we do it that way, anyone in future can find all the discussion under the common Subject title, so please do not contaminate the title by using it to discuss other topics.

Charcoal Gasifier No 2

Hi Gasification Colleagues,

While charcoal gasifiers are as simple as desperation determines, the choices as to how they are designed is very much a factor of applied knowledge, using the materials that might be available. In the main, we will only be using components made of steel, and using basic welding equipment for assembly.

What is not discussed in literature on the subject of gasifier design, is the philosophy behind the design, and the phenomena created by that design. It is very clear that far to many people are locked into a mind set of chemical equations, and mathematical calculations before first being able to creating the correct phenomena to achieve the desired results.

Hi Gasification Colleagues,

Back in June, I promised to give you some basic lessons on how to make a charcoal gasifier, and to explain some terminology. This is for those who understand nothing about gasification in a practical sense, so should kick start those with less ability or resources. It does not cover gasifiers that use raw biomass.

Gasifier and Engine Tables
Kevin Chisholm, October 11, 2006

Attached is a Spread Sheet "Gasifier and Engine Tables" that should answer a number of questions relating to diesel fuel displaced by using wood gas in a dual fueled engine, or the amount of wood required to provide sufficient gas to run a Spark Ignition (SI) engine of any size.

I put this Spread Sheet together, based on fundamental work done by Doug Williams of Fluidyne, www.fluidynenz.250x.com

Enter the engine speed in the colored block, in Table 1, and this gives results for an engine of 1000 cc displacement. In Table 2, the engine displacement can be entered, and this table gives the expected results for an engine of that displacement.

For a given engine size, if you know its petrol consumption now, the Table 2 would tell you how much wood you would require to operate the engine under similar load conditions. I hope you find this helpful

Best wishes,

Kevin
