There are other things that will make your flues leak. Pumping cold
water into a boiler with a low gauge of water will do it, if it does
nothing more serious. Pouring cold water into a hot boiler will do it.
For instance, if for any reason you should blow out your boiler while in
the field, and as you might be in a hurry to get to work, you would not
let the iron cool, before beginning to refill. I have seen an engineer
pour water into a boiler as soon as the escaping steam would admit it.
The flues cannot stand such treatment, as they are thinner than the
shell or flue sheet, and therefore cool much quicker, and in contracting
are drawn from the flue sheet, and as a matter of course must leak. A
flue, when once started to leak, seldom stops without being set up, and
one leaky flue will start others, and what are you going to do about it?
Are you going to send to a boiler shop and get a boilermaker to come out
and fix them and pay him from forty to sixty cents an hour for doing it?
I don't know but that you must the first time, but if you are going to
make a business of making your flues leak, you had best learn how to do
it yourself.
