Steam solution January 1st 2008 Bandvulc Tyres has knocked 8%,
(£10 000) off its energy bill by
fitting a Spirax Sarco system
which uses flash steam from
returning condensate to preheat
the feed to its boiler.
A skid-mounted heat recovery
system was introduced between
boiler feed pump and the boiler
itself. A plate heat exchanger heats
the boiler feed water using the
flash steam that is returning with
the condensate. Positioning the
heat exchanger after the boiler feed
pump is crucial to the success of
the entire scheme because the
feedwater is under pressure at that
point. This prevents water from
turning to steam, even though its
temperature is raised from 95 to
125°C before it enters the boiler. More articles from Spirax Sarco Ltd: |
