The total length of the pipe is about 48 “
Top cover is 4” blue pvc glued into the pipe with silicone
Bottom cover is any available grey cast iron flange with threaded hole, minimum size 2,5", favorable 4", with the fitting plug.
The nozzle is: female nipple 1" diameter, length 40 mm, thru the wall of the pipe ( same goes for the gas outlet )
This is solid welded about 4" above the bottom of the pipe. Solid thick welding for the heat transfer from nozzle towards the wall outer side. ( the thicker weld the better )
Top cover is 4" male plug, HDPE plastic, fitting in the female blue pvc glued in the top end of the pipe.
Gas outlet female nipple is about 3" from top
Distance between gas outlet and nozzle is about 40"
Useable about 20" before refill depending your charcoal.
My charcoal gets about 0,25 kg per liter, 20" is about 1,6 kg charcoal, runtime full throttle waterpump would be around 1 hour in this setup. A same sized engine generator would run a bit longer, almost double the time… if not under full load.
Engine size between 5,5 and 7 HP, running at 3000 RPM for the generator and 3600 for the waterpump
Nozzle depicted is made on a lathe from solid stainless, opening 16 mm
The filter, this is new, is inside the top of the pipe. Building another set now, to keep that as the “permanent” solution for this simple design.
yes, the blower is a air matrass blower, using them for 5 years now… no issues unless operator errors
The model aimed for distribution would be with a gas tank welded between the top and 20" above the bottom.
The name would be “Erawan Smart Farmer Gasifier”
