Hi All,
Well, I finally made a little progress on my gasifier upgrades. Here’s a few pics of the heat shield from the burner shell to cyclone preheat shroud. All the welds had to be inside so as not to interfere with a flush engagement of the components or the gasket material fit. The angle cut is there to accommodate the slanted side of the preheat shroud gas entry. I had to do this piece by piece taking into account the configuration of the openings and the not so squareness of the original build.
Here you see I left just the corners of the flange for assembly lineup. The heat shield engages the not so square hole just right. Note the slanted portion at the top right.
I elongated the holes for ease of assembly. Yes it’s not quite square, ratchafratch! Take your time when you build, these things come back to bite you in the derriere later.
Here you see the components fully engaged with a nice flush contact.
This was a real pita to do at this stage. Lessons for next build for sure! I’ve decided not to install the cooling tubes on my monorator hopper. The hopper itself, as it stands, gets out an amazing amount of moisture. I also have a condensate drain on my cooler which has only a couple of tablespoons of water per hour of run time. To checkout the condensate draining see post 251 video of third run at 6:21 and 2 tbsp water in cooler condensate drain at 7:13. Also check out the condensate draining on the video here, https://www.youtube.com/watch?v=ZBVpSLIBJmY at approx 1:20. This second video had no water in the cooler condensate drain sump. Cooling tubes seem unnecessary at this point. Anyway, I’ll have the tubes built for my next gasifier or this one if conditions warrant it.
To see how the preheat shroud and cyclone were mated, see posts 50 thru 57.
