new waste oil burner for spa heater

HomeDistiller Says:

Aug 20, 2011 - there is nothing inside the tube just the end of the copper pipe to input the oil, and i light it with a gas torch

Aug 20, 2011 - I'm building a heater for my pool atm. Just finished the burner tonight and the basic concept i want to go with. I looked at the commercial heaters and worked out what i want to give me the heat rise etc will be around 200kw output or 20L of WVO an hour. I'm going to use a radiator above the flame height of the burner and have cold air dilution to lower the gas temp. Are you thinking to use this design and enclose the flue pipe with a water Jacket?Where in Oz are you?

HomeDistiller Says:

Aug 20, 2011 - wow 200kw???? the pump you would need to stop flash boiling would be huge and the size of the burner would also be huge, that would raise a 20,000 ltr pool by 1°C every 7 minutes are you sure you need 200kw? i will be making a kind of "pot belly" burner with a coil around the outside (2 really, one short to maintain a temp, and one long to raise the temp) so it will also act as a patio heater

Aug 20, 2011 - oh and im in vic.

Aug 20, 2011 - I have a large pool that is about 75K Land a 60m Sq surface area. I'm in Sydney. I wanted to be able to get it up to temp in no more than 12 hours. The burner I have built will walk 200Kw in, I'm just a bit wary of the ability of the radiator I want to use as the HE to absorb that energy without boiling as you say. I'll be using a spa pump so flow won't be an issue. What about putting the copper inside your flue or running tubes up and down the length? maybe more efficent?

HomeDistiller Says:

Aug 20, 2011 - im not even sure a spa heater will handle it 200kw will raise one ltr of water by 47.8°C in one second i would want no soldered joints in the direct flame path, maybe make a multi layer copper manifold and even then you would want a large surface area to prevent fast oxide build up and the small holes. thats why i will put my pipes on the outside. burning oil and water REALLY dont mix well, unless you want a 10mtr high flame. i think you might want to look at heat retention methods

HomeDistiller Says:

Aug 20, 2011 - and things like solar and a good blanket to keep to heating energy down. maybe maintain a minimum temp so you rise time/temp isnt as much??

HomeDistiller Says:

Aug 20, 2011 - although it also depend on if you want to burn 200kw of oil or put 200kw into the water. the first is easy the later not so much lol.. i like your vids btw i subbed

glumpy10 Says:

Aug 20, 2011 - You know the numbers a lot better than me!How much wvo needs to be burnt an hour to get 200Kw?If figured it to be around 20.

HomeDistiller Says:

Aug 20, 2011 - that i cant tell you lol, i just googled amount of watts needed to raise 1 leter of water 1degC. To heat one 1 kg of water 1C requires 4186 J and a J=1 watt per second so 4186 watts will raise a ltr of water 1 deg C per second

Aug 21, 2011 - you noticed on your drum of oil SIMPLY says it all

HomeDistiller Says:

Aug 21, 2011 - yup simply a simple burner :P

glumpy10 Says:

Aug 21, 2011 - Thats how i knew he was in Oz before I read the channel description. :0)Seen a few of those tins in my time!

glumpy10 Says:

Aug 21, 2011 - It's a good design this. Have you seen the vids by ozzurit I think it is. He uses this principle which I think originally was a "Mother Earth" design for a home heater. A guy called Rodger sanders also worked and developed this concept. I'm going to try one of these for a small heater for an hydronic system for my home. My wife bought a stainless steel Cutlery drainer home that was full of neat holes and the first thing i thought of was how perfect it was for a burner. $3

HomeDistiller Says:

Aug 21, 2011 - yeah this is from ozzits design, just testing the idea

Jan 17, 2012 - I am in the USA experimenting with a waste oil burner at the moment. I have built a babington style burner. Yours looks much simpler. I am wanting to heat my pool. I tried gutting an old pool heater and scavenged about 5 gallon/minute flow off of it--was only able to raise the water temperature out about 15 degrees over what was going in--not enough to heat the pool. I am looking for better ways to transfer the heat to the water and do it quickly with more flow--any success on yours?

HomeDistiller Says:

Jan 17, 2012 - i havent gotten any further with mine as its summer here (35°C+ days and fire restrictions) can you tell me what the temp difference is in °C (cause °F is a very hard way to work out heat applied to water cause its not a temp scale based around water) and i'll tell you haw many watts you were getting into your water

samoht1977 Says:

Feb 6, 2012 - how do you pressurize the oil? 

HomeDistiller Says:

Feb 6, 2012 - i dont. its drip fed. and the heat rising up the flue draws in the air at the base to burn it cleanly

grandaddyc Says:

Feb 8, 2012 - Impresive! A water jacket on the outside would be an efficient way of heating the water.and a tapered flue might be more efficient still. like a "thermette" I quess you vary the oil flow rate by raising and lowering the oil container.you would not want to run out of water in the jacket but if it was at the level of the pool it would fix that. Now you,ve got me thinking ,thanks

Mar 29, 2012 - For a simple way to burn oil , it doesn't look bad. But watch this: It has neither a compressor nor a nozzle , but only a vacuum cleaner. There is no smoke going up the chimney . There is no soot in the stove and no ash in the burner. And this happens because of the high temperature which is given by the burner and the spiral-shaped air canals .

HomeDistiller Says:

Mar 29, 2012 - you mean a turk burner? the problem is they are very loud compared to this, this burns just as clean if it has a longer flue and this requires no electricity. it works the same way but uses hot air induction to force air into the mix.

Apr 19, 2012 - Get an old military immersion heater. They are supposed to run on most any fuel. The start up on them is a little hair raising though. I've seen more than a few fireballs from incorrect ignitions. I never had any problem lighting them though.
