Max. Thank you for the interest in my builds. I don't know if it is proper for you and I to have conversations about my problems on this group site, but seeings I have read a lot of OT coversations, I am going to take a chance until someone objects.
First; My pictures are on the Woodgas Builders Group. They are shown under '94 Blazer by ginfizz20
I started my first build back when Jim Mason had just completed a work shop where they powered a Chev truck with a FEMA type gasifier. Then Jim started work on the GEK. I like the pre heat set up so that is the basis of my first build -- I refer to it as a "suto-GEK". Right now I can not find the book out in the shop that has all the deminsions. When I am allowed in the basement I will look up my calulatios from FAO72 and Werner's tables etc. I will say that this was done for a 4.3 L engine at 2000 rpm. As you can see from the pictures of the "flare", it appeared to have a gray cone in the middle of the flare that I took to be water. Up at the engine of the Blazer when running the blower, it would drip water/tar out of the fan. I eventually stuck the lifters from forcing to run it. I was only able to drive the Blazer around the yard and up the hill a couple of times. I never felt the gas coming out of the gasifier was hot enough. I think I measured the temperature at the outlet of the gasifier at 600 deg. Farenhite. It does have a very good "moderator" that does a good job of collecting moisture. I was using "poplar" wood which I considered to be very dry, but always questioned why I got so much moisture from the moderator and also as seen in my flares.
The second build started out to be a copy of Mike L . LaRotor. I tried to keep all of my dimensions to what I had calculated. The nozzles were too close to the restriction. So, I came up with the idea of using a "tire rim" and mounting the rotors under it with the nozzles mounted in the rim. I welded a plate all the way around the rim to make an air chamber to feed the nozzles. I cut the number of nozzles in half ( to 5 ).In digging up this info I see I made an error in the nozzles diameters. Other than that the nozzle diameter- the height of the nozzles above the restrictor - and the restrictor diameter were the same as the calculations. When flaring this unit the gas was extremely volitle and instead of burning would actually "explode" like a shotgun. The temperature of the gas coming out of the gasifier was very hot -- I believe I measured it in the neighborhood of 1500 degrees F. I believe the photos of the flares are labled as to the GEK or the LaRotor.
My wife went down stairs and brought up some of my notes.
4.3 L engine at 2000 rpm; Max air/gas = .072 M3/sec; Max gas intake = .034 M3/sec; Real Gas Intake = .0272 M3/sec; Bg Max = .9 M3/cm2 hr; Area Throat S = 108.7 cm2; Dia Throat dt = 12 cm (4.72 inches); Height of Nozzles above throat (h)= 13.8 cm (5.4 inches); Dia. of Firebox d =.36cm ( 14.2 inches); Dia. Nozzle Ring dn = 27.6 cm (10.8 inches); Dia. Nozzles ( 10 nozzles) dn = .33 inches (21/64 ths.); Dia. Nozzles (5 nozzles) dn = 1/4 to 1/2 (error in this somewhere) TomC.
