Waste Motor Oil / Re: so winter approaches........... get building
« on: December 06, 2012, 02:15:56 pm »
mounted the header tank, put the pid controller on, heated the oil, and switched it on, wouldnt light with 80 degree  oil, nothing, 90 degree nothing, 100 degree oil and we are off, starts up and gives a good flame, the oil pump that usually supplies the heating oil to the nozzle now keeps the header tank topped up, and should it get too full it has a overflow pipe back into the sump, so i need a bit of wiring so i can make the burner wait till the oil is hot enough, no alarm output on the pid, so finding another way

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

your idea to make a burner cheaper is great, i can buy a chinese version for £500, with everything i need, now this chinese waste oil burner uses a UK heating oil burner that they have copied perfectly, it does not use any nozzle preheat at all and works fantastic,keeps parts and costs down (i bought one and copied it, the biggest part is the nozzle which isnt a hago/delavan/reznor or anything else so i bought one £20), the rest of constuction is very simple, easily copied and some scope to make money if you can buy secondhand burners which i did

ok here goes, the deepfat fryer keeps the oil at 90 degrees centigrade, and the siphon pipe is very short and held on the side of the fryer causing it to be heated by the oil etc, this also heats the nozzle, the nozzle holder is drilled and tapped with 2 holes one for the air and one for the oil, i was looking at having the nozzle threaded into the deep fat fryer, this would mean it doesnt have to be preheated and the level can be kept only 1cm below the nozzle.

Ive just fitted a shop bought waste oil burner BAIRAN BRAND, to a oil fired warm air cabinet, and took the time to take note of how its done, its really simple, and Adrian you could do it without a degree, if you could get a riello burner i can literally talk you through the conversion,the only bit you need is a nozzle and you drill the existing holder to suit so no machining, and no PID controller or nozzle heater, get the cheapest,smallest deep fat fryer, and you have a heater element,controller (90 degrees),overheat switch, burner done

hi, welcome, the site is kinda quiet till the winter takes hold, anways to your questions, i personally burn any thing that resembles oil, if you mix it all together you dont need to adjust anything, if you use diesel or something thats a bit more flammable you may find you need more air to aid combustion, (boiler chuffs, like its gasping for air)and ANY oil fired boiler can be coverted, im changing a riello burner (simplest to change)to keep me warm in my garage, where abouts are you ????

Waste Motor Oil / Re: Waste oil spill... What a mess!

oil is amazing, a little goes a long long way, it can be a very thin layer and covers anything and everything, great stuff most of the time, but a bugger when it spills

the biggest issue is that the oil needs to not only be very hot to allow ignition with a spark, and then with a pressured system the delivery needs to be very accurately metered, you would need to have a tank with the oil at about 90 degrees c and then a nozzle heater to bring it up to somwhere in the region of 220 degrees c i belive, waste oil doesnt need such high temps, needs more like 150 degrees c,

Welcome, yup Russ is right as it gets colder we have a greater participation, its cold here in Gloucester UK. getting the doors on my workshop then build my heater bigger and better, hows your set up

been on ebay and bought a tepperature controller and heater elements etc, just need some time to build it

im looking to buy my cartridge element from hong kong, just wanted to know actual size and wattage, think i can build it cheaper than CK, but cheers Doug

ive made me a heater, got the resevoir running at 90 degrees centigrade, but without a nozzle heater it wont stay lit easily,  if i blowtorch the feed pipe it bursts into performance, but where do you guys get your cartridge element from, and did we work out wattage??? oh and what dimensions are they

got one from our local junkyard/scrapyard
