The burner body is made of 3" black iron pipe fittings. The yellow line is air, the white one is oil. The burner has been working well at a oil temp of 80 to 90 deg. F. At anything above 100 deg. F or installed in a hot kiln I would switch to a flexible copper oil line.
The manifold has pressure regulators controlling pressure to burner and oil tank.
WVO does not burn well or even flow well in cold temps. A used hot water heater makes a good heated storage tank, with some modifications. A long firing would probably take two tanks.
Below: Though not a great picture, this is the burner in action.
Yesterday we went out and looked at the same pile of bricks we left last Wed. Yep, still short of hot face hard brick . So we made a pot of java and started counting arch bricks. Hmm short there too. Well no new kiln pics today. I'll use this opportunity to slip in a few of the wvo burner setup.
