[SEL] Mystery object

[Peter Lowe]

Hi All

Can anyone identify this object please.
I would say it is not a burner as there is no pressure pump. It looks like 
it boils something, but when you do the steam and water just leaks out of 
the top assembly like something is missing.
One of you gurus must have seen one before.
