Hi Steve , i am in the process of changing a few things on my setup ,so that may be the time to try and get some photo’s of the nozzle and how its set up through the drum , but in the mean while its so simple i don’t get the chance to update the build that often and while its working so well i leave it alone , we are going to have a sunny day today , so if i get a chance today i will empty my drum of charcoal and show you the inside and how the nozzle sits inside , i am sure it will have another build up of molten slag around it so you should get the idea and the only downside to me not using water drips or egr , is that i have to poke through the slag formation after a week or so from below , or do what i will do today and empty drum and take it out .
As for filtering i used to have just a simple 5 gallon plastic screw lid container filled with lambs wool and connected with plastic hose pipes , but it was only good if you ran for about 3 hours and then it was starting to get too hot , so i now use a 1 inch flexi stainless steel out of the lid of the 55 gallon drum over to a cyclone that helps drop the fines out before i send it down to my small gasifier that is now being used as a filter tank , its 8 inch dia by about 3 foot high made of mild steel with a aluminum lid where the gas comes out having passed through open cell / and a layer of lambs wool with a pile of pan scrubbers sat on top to save sucking anything up into the plastic oulet pipe that then goes for about 5 foot to a in line fine filter and then into the air mix valve and engine’s .
I just nipped out side and took a few photo’s to explain my ramblings better .
This is the 55 gallon drum with everything in place
this is the lid and outlet pipe , you can see how discolored the stainless pipe gets when its been run for 5 or 6 hours loses that lovely new shiny look
This is my small gasifer i use for running very small engined generators , but not used it in ages so now its a extra filter .
and this is the in line fine filter i use , again i normaly fill up the middle with lambs wool as well
Soon as i get a chance i will empty drum out and show you the nozle set up from inside and below , may not get a chance to video it running for a while but if i do will put link up , the next few days i am testing out a new insert for my drum to try and get a better run time from the large barrel .
