What does this pic tell you?

From what I remember..........
Exposed Iron + water + air = Rust


Googled:

4 Fe(s) + 6 H2O(l) + 3 O2(g) 4 Fe(OH)3(s)

That said, you wouldn't know what caused it. Vandals probably.

Probably lack of bypass. Most older installs around here didn't have a bypass plumbed in. I come across lots of oil boilers with red sand-like deposits.

Is that not just residue from combustion of kero, as judging by the 'whiteness' of and the amount of scale in the boiler it was over-aired

jimf

to me it looks grossly over aired quite a shallow chamber so its easy to do

It is burning diesel and the red residue seems normal enough to me. You seem correct on over airing as I was called because it was hunting. Blast tube fins a little sooty. In pic I thought there was signs of flame impingement near burner. It always had an 80s nozzle but I have changed to 60s. FGA and smoke ok on old and new nozzle. Some seem to be very forgiving boiler. Has a high flue without a draught diverter, so is probably both over and under aired at times.

Chamber is about 1.5 times longer than it is wide. Pic makes it look different. I will post FGA when I get home.

DGOBS

If it was hunting, only when cold would suggest over-aired (lifting the flame) or maybe the chamber/burner gaskets are leaking causing recycling

Good dose of dualx on those surfaces when hot will give you a lovely as-new boiler chamber

jimf

that rear refractory brick doesn't seem to be showing any signs of excess heat/flame bouncing off it

Hunting??

No Jim, none at all. The chamber looked a bit sooty next to burner and that along with shape of chamber lead me to decide on a narrower angled nozzle. What do you think? Going to post FGA's on next post.

what were the fluways up through the boiler like they can be a bitch to clean what I use is a wirebrush for cleaning the barrels in a shotgun can be bought in any gunshop and 1 of the best investments I made a few years ago great for the job

Wearb

First FGA before changing nozzle.



New FGA after new nozzle.

jimf

seems to me like you have a good set up there would be only nit pickin to try and find fault

depending on the weather on the day a fine day I always prefer to have the co2 at about 11.3 I think its gives a bit of leeway for the muggy weather from oct on but that's just me you might loose a little in efficiency but its usually hardly noticeable

It was all quite clean. They can be a little difficult, but correct brushes make it easier.
I got this set of brushes in Manchester a while back. Couldn't find anything suitable here. Didn't think of the shotgun one.

That's exactly what I need. What the name on them? Maybe I could find them online

I sourced them on Ebay by doing a search for Flue Brushes (that is where I got that pic from). They were charging an arm and a leg for postage, so I had them posted to a cousin in Manchester (for free). And then collected them there when visiting. I could have had them posted from my cousin for a few quid, but I was going there at the time anyway .

Just found my purchase details. Here is a screen grab with personal info redacted. Maybe it will be of some help. They were fine to deal with. Delivery a little slow, but they have delivery times on web.

Same here, the only difference being the very smallest brush, (unless it was in the pack and I've lost it since).
I saw them in H.M. Rialto last week, I think they're around 20- 25 euro for the set.

A lot of different ways you can get a build-up of rust in a boiler.
I was asking about specific circumstance

That's a good price. At the time I tried HM, DPL, Chadwicks, Woddies and lots more without success. Perhaps lots asking for them encouraged them to carry them. They come in handy.

What size diameter is the biggest brush head?

2" and smallest one is about 1/2"

+1 in all Heatmerchants at the minute

Have ye tried Dualx at all, does a great job on cast iron boilers, makes is very easy to remove the scale buildup?

Wearb

I haven't used it. I have often thought about it, but just never did. Does it have any downsides? I must get a mate to ask for it next time I am in a plumbers merchants :D;)

DGOBS

Only place you can get it is HWOS or Charlie

I find it great for lots of applications, give the boiler a decent hover, heat it up, then blast it with a dose, and comes up clean as new

Saw it in Charlie's literature alright and I will get some with next calibration. Seems to be the business. Would have been handy a few times in the past.

jimf

just spoke to Charlie and making myself a present of a box next Monday

have a particular boiler that I will be servicing next week and it should be a good test for it will post back after use

and it also gives me a chance to call to the office if ye follow my drift and its not to see Charlie hmmmmmmmmmmmmmmmm

just picked up the dualx a few hours ago as I was passing charlies will see how it goes next week

he has a lot of bits and pieces there as well I didn't know he was stocking

Granny wasn't there then. He mustn't lurking.
Looking forward to seeing before and after on the DualX. Am also keen to see if it adds much extra work to a service. Will you need to add a few bob extra to a service where it's used?

jimf

well it says 15/20 boilers per pack so if that's accurate I will absorb it myself for now unless I get a total pig of a yoke
wink wink I might recoup a bit of the outlay
