care of them – ideally through scheduled
maintenance.
A reliable and safe supply of hot water is
crucial for wash-down and Clean-in-Place
(CIP) processes. Traditionally, the food
and beverage industry has relied on large
shell-and-tube calorifiers that use steam
to heat water.
By replacing these storage tanks with
instantaneous systems that use compact
heat exchangers, like Spirax Sarco’s
EasiHeat™, plants can achieve energy
savings of up to 20 per cent. These
systems work by capturing and reusing
heat that may otherwise have been
wasted, and can deliver a constant supply
of instantaneous hot water at a stable
temperature. This reduces the amount
of steam required, which, in turn, cuts
fuel demand and the associated CO2
emissions.
Furthermore, plate heat exchangers are
easier to maintain and simpler to control,
which helps keep the system running at
optimum efficiency.
It’s important to remember that the
boiler house is the engine room that
powers the whole steam system,
making it a vital place from which to
measure efficiency. The only way to
obtain true boiler efficiency is to meter
all energy into the boiler (in the gas and
feed water) and compare this with the
useful energy out of the boiler (in the
steam). Energy monitoring systems,
such as Spirax Sarco’s B850 Boiler
House Energy Monitor, manage this
process, allowing users to react quickly
to any data they receive. If the monitor
detects a drop in efficiency levels, for
example, the cause can be identified on the environment, hence the reason
quickly and remedial action taken in why energy efficiency needs to be high
order to prevent unnecessary costs from on the agenda. By implementing simple
arising. The monitoring of systems also measures to help optimise the efficiency
enables energy and facility managers of the steam system, steam users will,
to benchmark the efficiency of boiler not only benefit
settings and operating procedures,
meaning energy and cost savings can be
measured and implemented effectively.
All food and beverage companies must
comply with certain legislation, and
some may also be driven by their impact
from reducing their carbon footprint, but
will achieve significant cost savings in the
process too.
