Alan if you search for Lister CS electric start - here or Google - you will see several vids that are simple & good. They are always an option if you aren’t confident with the starting components of your SOM and don’t care about keeping it original

Yes. Doesn’t like the wind. Seems to not make any smoke at all on a still day when the oil/air is consistent. Check out pic/vid of flue against the gum trees & the sky on a calm day

Waste Motor Oil / Waste oil burner Mk11 prototype working reliably-ish
« on: August 01, 2020, 03:36:27 AM »
See 30-sec video YouTube link if anyone is interested

https://www.youtube.com/watch?v=JrPAqyuBNcI

This is a Mk2 version of the prototype and it seems to do the things I'd like it to do:

Burn clean-ish and consistently with no energy input other than oil.  Start and run pretty much without smell or fumes.  Put out lots of heat and provide a "cook-top" with hotter and cooler surface areas.  Use a reasonable amount of oil

Pictures & short video tell the story, really

It burned 1.2 litres of oil in an hour and eight minutes.  I got it warmed-up, filled the little oil reservoir, set the flow to a pencil-lead sort of cross-section, set the timer on the phone and wandered off to do some other work.  It ran steadily and consistently for an hour and eight minutes without any intervention from me

I have made the "up-draft" burn chamber thingie with a 100mm BSPTM thread on top so it can just come off to be tinkered with

The flue thingie is on a flange so I can change it at will.  I put in a TEE with an 80mm drain bung on the bottom to facilitate cleaning.  It's 100mm flue atm - I'd anticipate going to conventional 6"/150mm flue sections if it works well-enough to end up in the shed

My observation, fwiw, is that this thing and its ilk are basically just one big draft/flue - it doesn't like interruptions such as a baffle I trial-fitted; but I have been starting it by tipping in about half a coffee-mug of a 50/50 diesel/petrol mix & lighting it with the butane torch.  It lights with a bit of a "whump" and the expanding gases shoot through and up and out the chimney with an immediate "roar" and it establishes a solid draft which continues as I turn on the oil a couple of minutes later; and it just burns happily away

Next step is to try it on various dilutions of the heavy oil of which I have tonnes - and then tinker with a Mk3 that might look a bit "nicer".  Might

Cheers

Perhaps SOM bits in a new box?

I'd appreciate any thoughts

Other Slow Speed Diesels / Bryce injectors

INJECTORS

Because some of the older big machines such as Blackstone/Miirlees have fallen under the “Lister” label in recent decades – I might just put these in “Lister” and in “Other”

I wonder if someone has a use for them?

I have four large Bryce/Lucas-Bryce NTDOB injectors – complete and still sealed in plastic-wrap and original boxes from what looks like a factory overhaul.  They were part of a larger auction and I would say they have originally been “spares” inventory somewhere like a municipality or a hospital where a large Polar engine or something like that has been working

I would guess the pictures tell the story, really?

Perhaps these would be useful to someone restoring or working an older large machine – I think this NTDOB (and possibly related/possible overlap NTCLB and NTDLB) series of injectors are from large individual-cylinder two-stroke diesels – but I stand to be corrected

It also seemed to me that injectors such as these in good condition might represent an opportunity for someone to machine an adaptor-sleeve to use them in a non-original application?

Stamped into the injector is the Bryce code:
“BRYCE WZ NTDOB175HO464

The boxes say “99-5367-7241” and that’s a coding number for parts that have had a military application in some way – perhaps a marine engine or a large generator/power plant?

99-5367-7241 is an American NSN (National Stock Number) in Federal Supply Group (FSG) 28, and Federal Supply Class (FSC) 2815 & FSC 2910
NSN listing part number 99-357 also references a listing #U1614

99-5367-7241 is also on the NATO Parts list in categories DRN2910 & DRN4780 as: part #2815-99-536-7241 “Injector assy F” also mentioning parts numbers OD28674 and K8098

In Britain they’re referenced with part # “8715” which is a Defence and Aerospace listing under the UK NIIN (National Item Identification Number) 995367241
UK NIN also references part numbers OD28674, 2815995367241 and 995362741

Bryce says applications include Miirlees Blackstone and Lister Blackstone engine-type ERS MGR two-stroke diesels and Wichmann AX engine-type diesels

I’d be relaxed about mailing these anywhere they may be needed.  I guess each box might weigh two or three KGs?

I guess anyone interested could message me?  Cheers

Waste Motor Oil / Re: waste oil burner "ozzirt" type. Works well
« on: July 12, 2020, 06:19:36 AM »
Okey-dokey

I realise this isn't a subject in which there's a lot of interest - so my apologies to anyone who feels his time is wasted by it.  But it's only really my time wasted

There are lots of simple draft-type burners around and they're capable of immense heat, limited only by one's personal courage, as far as I can see

I must have watched 50 or 100 YouTube vids of burners ranging from awful to unbelievably efficient-but-complex.  So a while back I posted some pics and a short video or two of my iteration of an "Ozzirt" type drip-feed burner - it was just proof-of-concept, really, but I was encouraged by the fact it would respond to "tuning" the air intake at bottom, midpoint and top (primary, secondary & tertiary burns - if you like) and the fact that was repeatable.  Plus it was easy to have it burn "clean" - at least in terms of exhaust output

So I'm 2/3 of the way of building Mk11 as mentioned a couple of weeks ago.  See pics attached?

It's still rough, still proof-of-concept.  I wanted to see if the Ozzirt drip-feed design would burn through a big chamber and around a baffle - to capture and dissipate a chunk of the heat - and also if it would do that with a "cook-top" top section which, in an ideal world, would incorporate sections that were "hot", "bloody hot" and "simmer"

So here's some ugly cut-and-shut construction.  It's a hunk of 300mm (12-inch nominal bore) pipe with a 12mm (1/2 inch) wall - should accumulate a bit of heat with a bit of luck) and the top is made out of some scraps of 12mm flat too

There's a base (not shown cos I forgot) which incorporates a stand etc . . ,

The intake/burner bowl/burner tube is a re-use of the one in the previous post - but I welded a section of 100mm BSPT male thread onto it and welded a 100mm BSP socket onto the bottom of the intake part of the big "stove" chamber - so the burner tube and air intakes assembly hangs off the elbow shown and is removable to play with as long as the thread lasts (not long I suspect)

At the exhaust end of the stove chamber thingie there's a 125mm flange welded in place two-hole-square, so I can attach whatever I like to it, flue-wise, simply by building it on the end of a suitable flange with two-holes-square orientation

Like any piece of amateur cut-and-shut, it's ugly - although it'll clean up with some weld-grinding.  Basically I tacked stuff together, heated it with the gas to bash into shape in the join areas and filled the gaps with weld,  It'll work well-enough to prove/disprove the concept

My aim is to have a "stove-type" burner which is safe-enough to put in my shed and which will radiate a chunk of heat and which has a "cook top" function.  So this is a first step towards that.  I wouldn't anticipate building anything that one would leave burning unattended

The base (not shown cos I forgot to photograph) incorporates a steel "tank" for want of a better word, made from 8mm plate, and with 40mm BSP sockets at each side - because I'd like to see if there's a safe way to "pre-heat" the heavy oil of which i have several tonnes available

So there we are.  Excuse long-windedness

Am I right in thinking I have seen 40/50mm plumbing non-return-valve units used on crankcase covers?  The brass-body type with the spring-&-seat arrangement?

What is the thinking?  The valve opens to allow crankcase pressure to escape as the piston descends?  Or do I have that ass-about-face?

Cheers

Waste Motor Oil / Re: waste oil burner "ozzirt" type. Works well

OK Veggie

See rough schematic attached?

I have most of the bits for Mk11 lying around the workshop and hope to go up to site this weekend with the angle grinder & cutting discs to take re-useable bits off of Mk1 and consign the rest to scrap

I guess I’ll build/assemble Mk11 out in the paddock in the same place so I can burn/tinker/tune . . .

An ideal outcome would be something that started up cleanly & fast and didn’t smoke at all apart from up the chimney.  If I can achieve that, and get it to burn OK on the “clean” waste oil of which I have potentially several tonnes – then I’d put one in my shed

It’s not the sort of thing you would leave burning un-attended.  Initially, at least, (I would think) you would want the major safety feature to be an oil reservoir that was quite a bit smaller than the burn bowl so that if something went wrong in the valving area . . .

Basic features of Mk11 might be:

A main body ex a 550mm length of 400mm diameter heavy-wall pipe (selected because I have it here in the yard), with a vertical baffle in the middle and a removable top “element” that would allow you to tinker with the baffle, or to make steel bits to hang down and pick up extra heat or whatever . . .

(In the past, in other applications, I have made removable top-plates like that from good-quality flat cast-iron because it doesn’t buckle or warp.  I have a bit or two here somewhere)

It would be nice if I could achieve a vaguely “oval” top plate, dead-flat, and around maybe 650mm X 400mm.  If that had, perhaps a “hot” centre and possibly a couple of cooler extremities – that would be great for sitting the frying-pan or kettle or whatever on

At the moment my thinking is to re-use the burn pot and burner/air tube off Mk1 initially.  I don’t know if a design like this will work OK with a bend at the top of its burn tube or not – I guess we’ll see

I’d hope to get onto building bits as I have time over the next couple of months – workshop availability permitting

Cheers

Veggie - I should have said, too:  the reason the whole thing is built as it is - is that it's all stuff lying around the workshop.  Total cost to me was $0.00.  It was just a proof-of-concept

Mk11 will have design requirements I guess.  But I'll try to keep costs low lol

G'day Veggie

I reckon the little bowl at the bottom is a bit neither here-nor-there.  You see so many designs and if the air flow is good - they seem to work OK-ish

That said I'd like to use a stainless bowl for the next one for a variety of reasons:  should glow red, might knock burnt residue out easily? . . .

With my current one, beneath where the oil drips in there's about 100mm of 20X20 angle, Vee downwards, like a little trough, and sloping slightly down, directing the oil flow to the centre.  I have no way of knowing if it makes a difference.  It certainly works OK lol

The reason I think the burn bowl doesn't matter much is that the fire is tune-able, so I figure the initial burn is OK.  Depending on how much air is going into the bottom pot, you can have the smoke from a busy, rolling, "coaling" black to almost clear - then with the addition of tertiary air it will burn dead clear (see the wee vid with the gum tress?)

And it only has about 1400mm of flue.  Would probably respond better with a long flue?   So I reckon the basics are good

Cheers

Waste Vegetable Oil / Re: New waste oil Burner.
« on: June 14, 2020, 08:57:59 AM »
I have been playing with a waste-oil burner myself with the objective of building something that can turn waste oil into clean heat in an off-grid situation (no blowers but maybe a we peristaltic pump if needed?)

Initial results are really good - controllable & clean once the paint is burnt off lol

Please see my new topic in "waste engine oil" if you are interested

Cheers, Mike
