Hi everyone, I am new to this forum but I am currently researching gasifiers and looking at ways to improve them for a specific use:
To give some background on my work: I am exploring the possibility of creating a gasifier for use in lower income countries as a way to burn wet biomass (such as fresh wood) post flooding for cooking and heating, when a lot of their dry wood supply could have been ruined and so rural communities loose access to their primary fuel source.
The key issues I wanted to thus fix was to let people burn wetter wood (around 40-50% humidity) and to reduce the amount of particulate matter and smoke produced, hence the use of a gasifier instead of a normal stove. The aim of the project is not to run an engine, but to use the gas for cooking, sterilising water, and heating, so I don’t have to worry about tar build up as much.
Reading some of the other posts on this forum, I came across a monorator gasifier (https://www.ekoautoilijat.fi/tekstit/monorator/monorator-eng.html) which uses a larger and wider container to better dry the wood and separate the vapour from the gasses to be burnt. An improvement I was thinking to it would be to channel the gas down the centre of the updraft gasifier before being burn to create stronger convection currents in the monorator container and so dry the wood quicker. I also wanted to know what people thought about having a second stream of air coming down the middle to be mixed with the gasses for more efficient burning (similar to how a top lit updraft gasifier works).
Another question I had which I haven’t understood is if the syngas fumes need to be cooled down before burning or whether that’s only needed to not damage an engine.
Let me know what people think about this design and any feedback is appreciated.
