Watermantle DriZzleR

Hello folks,
Acording to one of the big gasifier axioma´s, one should stoke the hearth of the gasifier as hot as possible. All kinds of techniques where aplied to rise the temperature inside the gasifier. Among them "preheating the incoming air with the exit hot gas stream. Or make the incoming air contacting with the convection heat of the hottests parts on the gasifier.
I do not want to mingle me in the fierce discussions that now and then take place in the gasifier community, between beleivers and the non beleivers of preheating necesity. This because the simple fact that I, and so also most of the "gasifier Guru´s" do not have enough properieate instrumentation and knowledge to back up either the pro or the contra statement.
Because this lack of knowledge I am forced to learn bij experimenting. But experimenting just for the case of the experiment is not awarding therefor I always am looking for a benifit.
Already In the begin of 2014 I made a watermantle round my gasifier, primary because i found it a shame to see the convection heat waisted, second; after a few hours in a room with a hot gasifier the shed becomes a sauna, third; to try to improve the overall efficiency of the system (put some exstra procents on the already high efficiency of a cogeneration unit) and last to see if the contrary of preheating (do a little cooling) would harm the gasification process.
That time, Although somebody, (a beleiver of the preheating theory ?), wrote me "This is NOT DONE !!; the results where not bad at all. I left the idea aside until now.Some time ago I improved the watermantle DriZzleR and made a longer and better test. See the results here:
