A new filter and a new pyrotouch

Hi All,

New Filter design, First part of the video.

I just posted a video of a test of my new filter setup. The previous filter a combination of cokes coal/woo/stainless steel shavings works well but created Too much presure drop. Also It was a real mess this coals SS shavings ... ugly smell and difficult to clean or to dispose.
This filtersetup is far more lighter in aplication and has very little pressure drop. Off coarse I have tested it only for 2.5 hours so I can not tell how fast it will pack up with dirt.

New pyrotouch/kompaktor/agitator. Second part of the video.

A DriZzLeR beeing a gasifier working in drip feed need to be feed the least possible amount of fuel. Also the flaming pyrolyse zone should be kept very shallow and always at the same level. This is easy if you have a constant load; then just DriZzle in on time interval. But coupled on a generator in island mode with various laod demands and thus various fuel consumption, on should have some kind of a level sensing device to feed more under heavy load and less in idle load. The Pyrotouch/kompaktor works fine with dense fuel such as pellets. With Woodchips the constant hitting the fuel, even if only very little force, is kompakting the reduction  too much and after some hours the reduction is packed densely and the gasifier stops breathing.
Also when DriZzling in pellets the distribute fine all over the flaming pyrolyse. Woodchips are falling down in one chute and pile up on one side of the fuel tube. The other side gets no wood and burns empty with as result a big hollow burn. So the Pyrotouch should have one more function exstra, an agitator and leveling function to make an even and level flaming zone. In the second part of the video I show an attempt to achieve this goal. Unfortunatly the mikroswitch beeing too close to the hot zone melted. Adaptations are needed But the principe seems to work.
