We should prolly bring our conversation over here on the controls stuff,
Anyways, today was a very good day me thinks. Ok so I had my theory on how this duel core reactor was supposed to work. Turns out it dont work that way at all!! This is not bad at all: in fact I think this is a major design step forward and I am also bringing this to the community right here. It is now open source for all to copy for themselves.
So today, I set the machine up like I had mentioned in the previous post. I shimmed the plane down to 0.0600" and fired it up. It took for ever flare off I fiddled with it for a half hour 45 minutes before I finally got it to light. Got to engine run and it ran weak and after 20 minutes or so something happened and it just spewed tar all out the intake air mixer valve. Ok well that obviously didnt work!!
So I decided to go the other way this time and added a jet plain, put the 100 thou washers back in plus added an additional set. Ok now at this point I am now doing something I had not tried yet. going back to the original proto and how I arrived at this design is the primary combustion would not stay put and kept migrating down to the second chamber and going out. So this new version has a second smaller restriction than the primary. So now I back to this one, I fire it up and it flared off right away, however, the reduction was still lit from before. So anyways I went to engine run and the genny fired right up and ran strong.
So now here is where I started making and seeing new observations, as the generator sat there and just ran, it ,kept running and running and Im waiting for it to die down some as normally I have to beat the crap out it to keep it flowing and shake the grate. It hardly needed any intervention including the mixer valve, One time something hung up and I think it was a bridge as after I intervened it smoked a bit out the intake valve.
Now a new observation, I checked the hopper level and didnt think nothing of it for a minute, but then it occurred to me there is no smoke in there. None!! I kept checking the entire two hour run and never was there any smoke in the hopper. This not normal at all for any of my pellet machines. So this is why there is no bridging; the fuel is staying dry the entire time it is flowing all the way to the combustion chamber. (the second one)
Ok now the top chamber, one observation I made during the second tuning of the machine is when I removed the top chamber I dumped all the fuel out when I did this. No char in there, if this top was working then there should be char in here. There was none. So at the end of the day I ran it down all the way to the first jet ring and poked my finger down in there. It should be hot right? Nope it was cold and I mean no heat at all, I should have burned my finger!!
Filter no condensate the filter is bone dry!! The tar trap did have some tar in after this two hour run, but I think much of it if not all was residual from the first run.
No smoke in hopper (this is significant!! no moisture accumulation in fuel)
No condensate ( baffled why that is: need a smarty pants to help me here)
Also fuel consumption is less (need more testing to find out much improvement there is)
Im uploading a video I took today showing the no smoke in the hopper. Ill update this point once its up and loaded.
