Hello Fellow Gassers,
I’ve started work on my new pressure relief lid. I found an old top cut out from the same style tank so the curves match up great(pic 1). There is a 3/4" overlap (pic 2), plenty of room for a gasket (s), one on the hopper and a mating one on the lid. Both will use Dan Cox’s high temp silicone impregnation method. Dan uses a different substrate, but, I’m trying this stuff. Pic 3 shows a beveled edge so that condensate will hopefully flow down the dome rather than drip back onto the fuel as it did in my last lid assembly. Pic 4. I ended up cutting this 8" d neck out.to get to Pic 1 configuration.
The next 4 pics show how I made my condensate channel from layout to forming the channel to the finished channel. The old dome lid will be gasketed and clamped in place instead of welded. Last, the unit drains continuously, but can be emptied while operating. Close valve, unscrew PVC tube, empty tube and screw back on, open valve. I could put a boiler drain on the bottom of the PVC tube.
Coming soon, the lid seal and operating mechanism.
Pepe
