I came across an LPG cabinet heater with a dud ignitor.I became the owner for the princely sum of $1 .
Having got my treasure home,I proceeded to dismantle the heater,and came up with some interesting stuff.
This type of heater has the regulator and ignition switch all rolled into one:
This is not a lot of use to me,but I just showed it to let you see what we've got here.
Here is the potentially useful bit,the ceramic elements:
There is 1 single element(broken),and a double.I put the broken edge to a belt sander,and it comes off beautifully smooth.I think I like this stuff ;D
There are 2 jets,1 for each element,According to the label,the small one is .68mm,and the larger one.86mm.
When examining the jets a bit closer,I found they were marked 62 and 88.Now I don't know what to think re jet size.But in any case,they will be too big for a burner for my boiler:
I've studied all the previous threads on burner design,but I haven't seen anything on using these type of elements.They are available commercially,but at a high cost.
Having laid out a whole dollar,I have not much to lose.
I understand that these elements need an air supply as well as the gas .But the commercial ones seem to have a rather large casing under the element,around 1" high.Is this really necessary?A slightly lower one would be better under my boiler.
The elements were fitted in their Box with some type of cord around the perimeter,and a rubbery type sealant was used to seal the corners.Could I substitute silicone windscreen sealant or similar for this?
The gas was supplied to the element's chambers by some nice alloy tubing ,which I kept as well:
There was one little item in the electrical circuit I didn't recognize.It's a round thing,about 5/16th diameter,fitted in a plastic housing:
Anybody have a clue what this is,or what it does?I don't think I need it,since I will light a burner manually,but inquiring minds want to know :big:.
For those of you who are still awake,thanks for wading through.
