Waste Motor Oil / Need some advice re the burner
« on: February 05, 2013, 01:59:36 pm »
Hello everyone -
I'm a newbie here and am making my first heater using the Roger Sanders plan, which I've tried to follow as closely as possible. I have the unit in a test state, meaning I've constructed it, welded holes and gaps, installed a door and had an aluminum burner made. wont stay lit after priming. For purposes of testing, I've been dripping oil into the airpipe via the copper line using an IV apparatus, but let the burner get good and hot first. After letting the kerosene do its initial burn, I add just a little more to get the burner hotter, then start a slow drip as indicated in the plans. However, even though the burner gets hotter than heck, once the kerosene burns off, I get a flame out and not sure why. So I have several questions: 1) are these units dependent on precision conformity to the plans? For example, roger says the flue pipe should be a min of 6". Well, mine is, although it is double walled, making the inside diameter more like 5.75 2) it there a sensitivity to the distance between burner and end of the air tube. 3) what about the air restrictor? He says 80% restriction. 4) would outside wind, even though fairly light, impact anything? 5) any ideal height of the burner from the air tube? I've attached a pic, which shows it in rudimentary state for testing. Thanks in advance for your advice !
