johnycarper Posted August 26, 2011 Share Posted August 26, 2011 we have just had our oil boiler serviced and the engineer when he left had fitted a gicleur 0,60*60 i have never seen one before and wondered what they are.It looks like a bolt with a small piece of stone attached.Just wondered if anyone can tell me what its for.

cooperlola Posted August 26, 2011 Share Posted August 26, 2011 Hmm. Well, I thougt a gicleur was a nozzle or a jet (as in a carburetor etc) so what you describe doesn't line up with that at all. It obviously has another sense which I don't know, or the gicleur is just one part of what you've been supplied with.[8-)] Link to comment Share on other sites More sharing options...
Ron-sur-Marne Posted August 26, 2011 Share Posted August 26, 2011 The Gicleur is the jet that sprays the pressurised fuel into the combustion chamber and controls the shape and form of the flame.(Think of the fuel injector on a diesel engine if that helps... or the jet/nozzle on an old fashioned blowlamp that you used a pricker to clean out ).It is fairly normal to routinely change it at each year's service - theoretically it could be checked on a test bench - but that would probably cost more than just fitting a a new one.The numbers are the size of the jet... Hope this helps, Link to comment Share on other sites More sharing options...

Ron-sur-Marne Posted August 26, 2011 Share Posted August 26, 2011 Just seen the previous post... The Gicleur looks like a small fat bolt with a very fine cylindrical gauze filter at one end.... if yours looks like a piece of stone, it needed changing! Scrape your "stone" to see if its really a thin brass-looking mesh. Link to comment Share on other sites More sharing options...
cooperlola Posted August 26, 2011 Share Posted August 26, 2011 Maybe then, Ron, the gicleur which Johnny described in his post is therefore the old one which the service engineer replaced, rather than the one he's just put in. Let's hope so! Link to comment Share on other sites More sharing options...
johnycarper Posted August 27, 2011 Author Share Posted August 27, 2011 Thanks for all the replies and i think it is a jet of some sort as its smells of diesel and is well gunged up as its the first time its been replaced in the 5 years we have been here,but we have a new guy this time and he seems a lot better and more thorough.
