A couple of pieces of obtanium have conspired to become a small engine gasifier.
From left to right: cooler, water drip threaded into primary air inlet, heat shield, reactor body, sealing flange for pass thru nozzle.
The nozzle is a 12" piece of 1-1/2" schedule 80 pipe with a tungsten carbide sandblast nozzle threaded in vertically.
these carbide nozzles come in various sizes so I can experiment for best match to engine and loads.
This old oil filled heater is becoming a cooler by blocking the gas flow between two of the chambers in the top to give it 4 cooling webs going down, then through the bottom and three paths up
