Serial cost savings
January 1st 2008 Recent upgrades to the boiler
house at Kellogg's Wrexham are
set to reduce energy costs in fuel
oil and natural gas and, at the
same time, meet all foreseeable
legislation on emissions.
When the plant opened in the
late 1970s FKI Babcock, now
incorporated within Wellman
Robey, supplied two of the three
steam raising boilers that are still in
operation today. In 1987, a fourth
Wellman Robey twin furnace unit
was installed. This boiler, rated at
46 000 lb/h (20t) running at 10barg
and firing heavy oil, became the
main steam supplier.
Several fuel saving features have
been incorporated, with savings
already being achieved from the
Economisers fitted in the boiler's
rear smoke box. Economiser tubes
have serrated fins which increase
net efficiency when firing on natural
gas from 89.92 to 93.26%, with
light oil now being the secondary
fuel. A speedy pay back is
anticipated. More articles from Wellman Robey: |
