The no-weld gasifier was fired up, last night. Chunks of softwood off-cuts were used as fuel. Doused with a little meths, they were ignited and a fire took hold without any problems.
The lid with the blower was placed on top and smoke was soon seen coming from the gas outlet pipe and just about everywhere else too.
Sealing all the gaps with fire cement will mean that the gasifier innards will not be accessible. A redesign is in order so that gas doesn't leak out and the gasifier can be dismantled when necessary.
There are some interesting designs on YouTube that I will incorporate into my redesign. The G3-I is one such design that I am interested in. Although it is welded together, it is a simple design that might yield ideas for the no-weld gasifier.
