Steam
12
Steam is used throughout industries for
process and space heating. Within the process
industries, steam is used in oil refineries; pulp
and paper mills; chemical production, such
as ethylene and ammonia; food and grain
processing; and textiles.
Refineries and chemical plants use steam tracing
to reduce pumping costs of viscous material
and prevent freezing of process piping. Steam is
used for heat exchangers and reactors to assist
or create process chemical or thermal reactions.
Paper mills utilize major steam generation
systems to generate power and to dry paper
products. Steam is widely used for district
energy systems found in major municipalities
and central plants of universities and hospitals.
To minimize piping cost, steam is generated
and distributed at much higher pressures and
temperatures than required by the process
load. Fisher
®
regulators are utilized in these
applications to reduce the steam pressure to a
usable level and to accurately maintain process
fluid temperatures.
* Maximum temperature limitation may vary according to body and construction materials.
