FGA Settings

Wearb

I had a customer call me this evening to say that damp patches are appearing on the outside of his chimney in the boiler house. (bottom half of chimney is in the boiler-house) He has a Bongioanni cast iron boiler with stainless steel flu coming from the back of the boiler and and going into (at about 45 degrees) the clay-flue lined chimney. The chimney isn't lined with a metal flue inside the clay flue. I explained that this is necessary and he is having it done next summer. The boiler was way over aired before I cleaned it and set it up. I know this because of the amount of adjustment to the air setting on the Riello burner.
I am calling back to him tomorrow and am going to increase the air and therefore the FG temp. I am hoping this will solve the problem.
Anyone have any ideas on this course of action please?

Meant to include FGA settings.

All those settings seem fairly good to me especially if your also getting O on the smoke pump, chimney temp is good as in high enough for it not to be causing your damp spot problems, chimney does need to be re lined as it's the problem.
Point out to the customers the difference in efficiencys of boiler flue temp. condemning 50 degrees V your 220+ wasted out the chimney, he might be better off fitting a new boiler and forget the old flue.
All your FGA readings looked ok except the CO which looked low ?

I would try and persuade him to have a SS flexi flue fitted.

Thanks Billy and Scudo. What do you think of my suggestions if he doesn't want to do flue during winter?

It will knock the eff down but showing him the 2 print out and explaining how its costing him money to warn the chimney may persuade him to bring it forward.

I will put in a bigger nozzle and set it up with a higher flue temp. I don't think he will mind some loss in efficiency, so long as he hasn't to do anything with it before the cold weather ends.

The lower the better I thought!! I've often had 1 or 2 ppm on an oil boiler

Get new boiler and save money. Increasing flue temp. won't fix chimney in my opinion.
Min. is new liner.

Wearb

He reckons he didn't have that problem before the service and does not want any work done during winter. I think I will get a half bucket of ashes and scatter it about the heat exchanger and combustion chamber and see if I can find his old nozzle :):)

A Christmas jingle to my re education !

( high Ho, High Ho it's off to work I go )

Ok ok it's not a Christmas tune.

Your not the first to not always get my humour !!!

I've never got co below 15ppm, normally I get 25-35 which I thought was good.?

Well that is good but on occasion I've seen it low. Often under 10 ppm. I doubt I'd be educating yourself on oil boilers!

I totaly have to 100% agree with you and so does my ego !!

Never seen it, if i have it below 50 on an outsider and 30 on an insider i'm happy, i don't go looking to break records.

I regularly get below 10....Just checked 10 random records and all were below 10 and most below 6

Billy Bunting

You never know exactly what your burning in my manor. :cool:

i average around 20-30 but would be more than happy to leave it at that.

I would be happy with that too, but it just happens the other way.

When you can buy 1000lt of "heating oil" for €600 delivered you need to question just what they are selling.

If I can it below 30 I'm happy but have reg got it below 10 my own is 5 on last check about 3 weeks ago but I'm like DTP I thought the lower the better as well

It is a long time ago since it was to be had for that. Probably mixed with used cooking oil :):):):)

Of course the lower the better, its like an ocd, just won't press print until I can get it as low as possible, hopefully single figures!

up around the boarder counties and around the industrial fishing towns there are always bargains to be had.

Your PLACE must must really smell or are you trying to COD us !

Getting below 10ppm is a bit fishey.
