Improved Oil Burner-reduction NOx and CO-Blue Flame

[bidouille23]

Hello ,

news, then the tube was too hot, it melted and it is turned up in the direction and at the place where the flame of the burner was to type, it is quite impressive, I would put a photo ...

So I replaced it with a shorter tube which does not redden at all in the same way, but the flame is still as disgusting .. no warhead .... I would come back to this below ..


Otherwise, joint between the burner and the support ok
Door seal ok

pump seal ok

Assessment, in spite of several different adjustment tests I can't even get the previous adjustment, I didn't have 10 leads to go this morning so I did the best, assessment, I have a small gain on the CO by compared to the origin but this thanks to an addition of air which makes the yield plunge ...

In short I really wonder if my sprinkler is not in question ??

What do you think, since there is no heater, I think I have to go back to 0.45 Gph instead of the current 0.4 ...

In addition you use full sprays, I tried the hollow ...

In short I was bothered to order a 0.45 gph 60 ° S from steinen, or else I stay on the spray in hollow?, But in 0.45 ...

I prefer to go back to the manufacturer's specifications, it will be simpler, I could remove doubts and therefore move in the right direction ...

If with this nozzle I still do not have a warhead flame I will suspect the pump, if the flame is disgusting it is already badly barred amha ...

In short, the next issue ...

see you later, I never give up ...

hi hack,

if you don't push the flame hook assembly to the max, you will have nothing! Have you tried well and to what extent?

normally if you push it to the extreme, it goes off = the flame goes out, because there is too much pressure, pressure that we seek here for the blue flame. at this stage of the step it is simple: it is enough to go back. ditto if the flame detector secures the burner because it cannot see blue (only yellow)

it is obviously necessary to increase the fuel injection pressure also if you have chosen a smaller nozzle.

air adjustment at the end according to CO

good luck, if not film how do you do? I remember at the beginning I couldn't do it.

Hi Jonul,

if you don't push the flame hook assembly to the max, you will have nothing! Have you tried well and to what extent?

I tried the two extremes, output fully and retracted fully, the flame became opaque in the extended position and translucent in the fully retracted position.

it is obviously necessary to increase the fuel injection pressure also if you have chosen a smaller nozzle.

the pressure cannot be more than the maximum that I give him ...

Appraisal: for the moment the pump makes a weird noise and the filter almost completely empties, suddenly it cuts, and it starts again ....

I primed the pump as indicated in the maintenance manual ... by the vacuum gauge screw, I still was checked today quickly zef ... I will re-read the doc but I am sure I followed the instructions ...

So since I put a nozzle smaller than the recommended one that makes a noise and a not beautiful flame, the assessment is for the moment simple for me suddenly, without heater I think I am wasting my time with this nozzle 0.4 ....

I buy one of 0.45 tomorrow ... we will see, if it is the same problem with the 0.45 is that I may be put in the air the pump ...

Already if I manage to have a flame that looks like a flame it will be an advance ...

more and thank you, I try as you said jonul as soon as I have another nozzle ....;)

I don't let go ...


I just solved the stupid riddle, which pushed the heating engineer last year because he did not understand why the boiler would shut down and resume continuously from a certain time of the year, as if by chance. 'winter ... and that's how it looks since installation , over 19 years .... the delirium you will see .... and there are two or three different "plumber_ heating" who passed (either they sucked or they really took her for a pigeon). ..


so I changed the nozzle, I asked a 0.5gph S 80 ° c for better cold ignition, the 0.45 gph will wait later, I needed something because even in Brittany it snows sometimes and it's the case ...

In short it is not the 0.40 gph nozzle which causes the suction noise of the pump ...

cleaning of connection lyre, re cleaning of filters ... in short everything is clean ...

So I go up the line to the tank, I look at the connection, the dip tube is a flexible oval thing, it's perfectly the kind of thing that must be crushed under a depression ....



I look at the level in the tank, just below the level of the burner, so it must have pulled hard enough to crush the pipe, and when the level is higher no bp, to this is probably added the viscosity which increases with cold .

In short I unplug the lira at the filter outlet and I immerse them in a clean oil can ....

Ignition, bingo ... more rupture more strange noise just the breath of the flame which does not extinguish any more, it is hot in the house this evening, I will thus be able to correct the problem of the plunger tube .... and then back to the blue flame .... finally a priori this one I should have it ...


Morality a piece of tube badly chosen can carry serious prejudices .... financial and in terms of pollution ....

see you

[Capt_Maloche]

Yep, it's a chain of events

for 19 years you say? well it must be good the day you solve the problem

[bidouille23]

She is rather happy that it costs her nothing, and happy to be hot ... Still, she tells me that this boiler has always been messed up from the start, so 19 years from the start;) .... me i cross i am like that even if it may be an exaggerated chouilla,;) ..... but who knows ....
In any case it's been several winter that it has heating cuts, I think we can say that it is soon definitively finished (after repair of course) ... and the nickel flame will be there like the cherry on the cake ..... but in everything as you say it makes dubiendanstoncorps when you're hot;) ....

[jonule]

good game !
you will see with the blue flame, it makes less noise too; =)

Slut,

problem solved yesterday, the constant level filter remains constant, the suction noise disappears the burner is adjusted as best as possible, following the manufacturer's recommendation of the burner, and end of adjustment with the combustion tester ...

Co fixed at 17 ppm or 0.017% and yield 87.7%, nozzle of 0.5 gph 80 ° c because it is winter and I have no idea of ​​the type of fuel oil, it is not marked on the invoice ... short

I link this too ...

with this induction tube operation, I changed all the seals: door, door bottom, flame vision etc ...

gasket, there is no simple piece of metal, it is true that it is a nice leak, I will glue a flat braid, a small tightening nut and voila ...

So I change the expansion tank, which gives signs of weakness and two taps which leak suddenly because too much pressure, and I go back to work ...

Hello !

I am new on your forum, which I find very interesting and very comprehensive.

I have a GTM 1104 De dietrich low temperature from 1999 with M 1 S burner that I just lowered to 24 kw. I hope to switch to the "blue flame" house burner this fall, for now I am content to learn by reading you.

Would you have feedback on your experience in terms of boiler fouling, consumption, resistance of the induction tube over time, stability of the settings?

What material and what thickness to use for the recycling tube?
For the measurement of Co I thought of using a reagent pump Co Brigon (10 to 3000 ppm).

I would also like to know your opinions concerning the draft regulator:
I installed a stainless steel "Tigex 25" from "SPX" on the purge tee of my chimney, set at 12 Pa and the difference was immediately obvious:

- better head pressure (from 1.2 mbar to 2.5 mbar),
- easier, more precise adjustments, more stable flame and easier starting,
- smoke temperature lowered by 20 ° at the nozzle,
- + 1% yield,
- better tolerance to excess air, greater resistance to flame release,
- much less condensation in the chimney and in the hearth.

I think it improves the functioning of the oil burners by lowering the temperature of the fumes and limiting the discharges by over-drawing. Do you think it is compatible with the assembly of Capt_Maloche?

[Capt_Maloche]

Completely

Recycling only takes place in the home,
For the manufacture of the tube, the greater the thickness, the more durable it will be, mine will last 2 or 3 years in 8/10 mm

after they degrade a little
