Steam Systems - Flash Steam
John Herbert
Director
Kelcroft's expertise covers a range of E&M engineering solutions for
the built environment including a particular specialty steam and condensate
systems primarily used in the healthcare, manufacturing process, catering
and industrial sectors.
If designed correctly, Steam is an efficient medium for transporting energy. It
is flexible, and suited for both the built environment applications and
industry applications.
Kelcroft E&M solutions provides solutions for the built
environment, that others can't provide, we can design, energy smart
Steam and Condensate systems, including flash steam, energy recovery
heat exchangers and fuel efficient plant.
Smarter design, is built-in not an afterthought using the full
potential, for example it is often overlooked that condensate can
create flash steam taking advantage of steam energy to lower your fuel
costs and reduce your energy bills. And it is backed up by users, a
survey of FM managers indicated that lack of energy efficiency measures
is the biggest headache for operators.
Kelcroft's solutions includes steam and condensate systems for
healthcare, catering and industrial facilities. Covering cook-chill, steam
boilers, steam-to-water heat exchangers, steam control, steam traps,
conditions surveys, autoclaves, sterilizers, and catering equipment,
laundry and industrial process steam applications.
What is Flash Steam?
Flash steam is low pressure source of steam created from
the potential energy in the condensate effluent from a high
pressure steam service to a turbine, or other process.
Flash steam can be generated to provide heat energy for other
processes and equipment, therefore utilizing the full potential of
the heat energy stored in the steam condensate before it is
returned to the central boiler plant.
It is economics driven, and a cost effective energy saving
solution to a number of engineering challenges, and it lowers your
operating costs. Flash steam can be used for process purposes, or
pre-heating raw water to lower your fuel costs.
Have energy conservation "designed in" from day one, not as an after
thought - Kelcroft's energy skillbase and experience lowers your total
cost of ownership, saving money, and that in turn lowers your
environmental footprint.
How does flash steam work?
High pressure hot water (Condensate) entering a lower pressure
region will instantly evapourate to create low pressure steam.
The process depends on the enthaply or heat energy within the
condensate and the pressure, this process is called flash
steam or flash steam recovery.
The low pressure steam created in turn can be used for domestic
water heating, air conditioning chillers and other low
grade energy applications before the energy in the condensate
is lost.
Advantages to use flash steam?
Generally its created and used locally, close to the process
equipment. Where the Condensate has sufficient energy the
condensate can be "flashed" into low pressure steam, and used for
commercial process that doest require superheated or high pressure
steam.
For example high pressure condensate from an
electricity turbine outlet could flashed into low pressure
steam for process needs.
Having a local, low pressure steam source is economical because
the shorter pipe runs and the equipment for low pressure steam is
more cost effective than high pressure components.
The exact application depends on the system and the secondary
application.
