I am 18 years old and thinking of going to school to become a boiler
operator but I do not know the future of this occupation.

Will there always be a need for boiler operators and engineers? Or is
this a dying occupation due to steam boilers being replace by a newer,
more efficient technology.

Join the Navy and they'll teach you about boilers AND pay you at the same time!

I'd suggest checking out the U.S. Department of Labor: Bureau of Labor
Satistics'Occupational Outlook Handbook. It gives great information on
almost any occupation you can think of. The link below is to the
information on Stationary Engineers and Boiler Operators.

I am a Second Class Power Engineer in Canada. I can see no changes for
a long time , You see , until a substitute for steam can be found,
that is what We will use. Even nuclear power is still just generating
steam. With the demand for power on the rise, it seeme like a good
choice.
