Screen tubes, yes, but whats a screenING tube or a "preheater downtube"
??? You love to nitpick terminology about which you have absolutely ZERO
knowledge and now you pretend to know something about boilers and write
terms like that??

What a loser wannabe you are, Nil.

And you really do need to sort out the antagonists in your paranoid
fantasy life. Such terms are the product of your own dementia.

Hell, you can't even keep your own identity straight and now you are
attributing your own delusional writing to me ... what a loser.
