Steam
for process heating (industrial applications) can be produced in
either the classic fire-tube
steam boilers or in the compact steam generator boiler, and they
will be gas-fired or oil-fired (burner).
If you are not
sure how to choose - then
it might be a good ideas to read more using the link at bottom
of this page, about how to
select between these two types of steam boilers of different principles, - to
ensure an optimal solution
for your particular task.
Steam generator boilers are designed with forced circulated feed
water that evaporates when passing through the inside of a tube
formed as a winded-up tube coil. They are therefore also called
water-tube steam boilers.
The alternative to this is the fire-tube steam boilers, which are designed
differently i.e. as a pool of water
gradually being evaporated by means of heat from the submerged
combustion chamber and bundle of tubes through which the flue
gas passes on the inside.
The links below explain what this mean for the steam boiler
features. |
Steam
can also be produced on electric steam boilers. These
types have become a good environmental option in a time where wind power, water power and nuclear power
can deliver electrical energy without producing CO2
and NOX.
The electrical heated
boilers are
fast and economical to install, but they are still often expensive in use and
therefore most common for for rather small steam capacities.
The most environmental solution
with the lowest operational costs, is however the
exhaust gas steam boiler offering steam production from
waste heat utilization.
A special design of steam boilers also offer
customized solution for
clean steam
used for instance in food industry and for other clean
applications. |
