with some sucess and some failures, ive purchased a chinese waste oil burner (bairan manufacture), it was £500ukp spent and came with everything i needed to retrofit this to any boiler, well ive built a hot air blower using all waste materials from my local junk/scrapyard, by using a propane gas cylinder on its side as the main furnace then an arrangement of pipes to make a heat exchanger/chimney, got a decent blower to get that air shfting 90 degree c air is lovely in my workshop, maybe a bit hot at times
Ive now dismantled the chinese burner down to nothing (my inquisitive mind), to see how it all works, ive tried to copy it without success, it would light but only if i heated to nozzle up, so tried to use nozzle heaters. But still though if our chinese friends can do it so can i. the part i needed was the nozzle, whilst any siphon nozzle works to an extent, the right nozzle makes it so easy, this nozzle isnt any standard nozzle, apart from having no markings or numbers, it also has 2 "o" rings, which no-one could identify, so i bought 1. £20 later it seems to flow far better,
got a couple of PID controllers, one as a spare the other to keep the oil at 85 degrees c in the header tank
Just bought a decent TIG welder (expensive toy), 1st job is a heated header tank from 1mm stainless, went well, all done, 1 weld was dodgy rest went well (first go at tig welding)
Sump tank with grid so i can do oil changes and leave filters to drain made, a couple of tiny leaks easily blocked up, now to mount the header tank and get it working
