The utility of steam is multifold and can be put to use in a
variety of industries for multiple purposes. Steam is a secondary source of
energy since it is produced from water by combustion of any type of primary
source of fuel in a boiler. Steam is produced out of a single process of energy
conversion; it is a cheap source of energy.
Following characteristics of steam make it an ideal medium for
heat transfer applications:
·
Efficient and
economical to generate
·
Uniform heating - easy
to distribute
·
Easy to control
·
Easily transferred to
the process by its own pressure
·
Steam plant easy to
maintain
·
Heat transfer takes
place at constant temperature
The applications for steam are heating processes in plants and
steam driven turbines in electric power plants,
used by the massive
petrochemical complexes to the local microbrewery, steam is an integral part of
these processes.
Steam is one of the most versatile utility in the industrial
energy arena today. In addition to simple heating applications, it can also be
deployed in various industrial processes like cleaning, sterilization, drying,
concentration, separation and evaporation.
·
In culinary
applications, it preserves flavours, textures, and retains nutrients. For
processing of vegetables and food, steam is used for sterilization and drying
under vacuum.
·
The use of steam in
the industry for the purpose of cleaning does not harm surfaces, motors,
bearing seals, sensors and machinery equipment. Hence the requirement of mask
off or cover equipment prior to cleaning is not there. There is very less
chance of any cross-contamination and thus it helps in faster clean up.
·
The freshwater,
naturally available from various sources, requires varying degrees of treatment
before being fed to the boiler. Treatment of boiler feed water prevents the
formation of scales and deposits, removes dissolved gases, protects against
corrosion, eliminates water & steam carry-over, optimizes boiler efficiency
and minimizes maintenance costs. Improper or nonexistent feed water treatment
is the major cause of boiler failure.
·
In biotechnology
applications, steam is produced in various grades of purity. Steam ranges in
purity from boiler grade for routine tasks, to culinary grade “Clean Steam” for
food and dairy, and goes up to super pure, pyrogen-free steam for
biopharmaceutical and intravenous use.
·
In case of “dry
saturated steam” there is a definite relationship between temperature and
pressure of the steam. This characteristic of steam helps in controlling the
processes precisely.
·
In the frigid oil
& gas fields, steam is used for heat tracing of tanks and pipelines to keep
processes moving.
Steam is a safe, flexible, economical, aseptic, and
environment-friendly. Steam can be generated through combustion of fossil
fuels, biomass or biogas. In the thermal power stations, steam is required to
be produced in huge quantity for generation of electricity. The steam has to be
produced at very high pressure (>150 kg/cm2) and high temperature (>
5400C), to produce steam in abundance, large volumes of feed water are supplied
to the boiler. Although feed water cycle of a thermal power plant is a closed
loop process, there is always some loss of water while it moves through the
closed cycle. This loss of water has to be made up by addition of treated water
into the feed water tank via de-aerator. Feed water contains dissolved oxygen,
which can cause corrosion in the boiler tubes. Hence the dissolved oxygen must
be removed from the feed water. This process is carried out in the de-aerator
with the help of steam. De-oxygenated and heated feed water enters the boiler
by means of feed water pump, where it is further treated with chemicals.
