One company to benefit from
long term boiler hire is
Stowmarket based PPG
Industries. Originally the paint
manufacturer had two 10t boilers
running on heavy fuel oil with a
large 8in distribution system.

To check efficiency, East Anglia
University was asked to undertake an
indepth steam survey. It calculated
that for every meter of the 8in lagged
steam main it cost £400 per year in
heat loss. It was also found that the
site load had reduced to 3000kg/h for
process and in winter a further
3000kg for heating.

PPG’s maintenance manager, Jim
Mackay was tasked with overcoming
the problem. Initially a 500kg/h
steam boiler from Byworth was hired
to heat the paint stores which was
the furthest distance from the boiler
house supplied by the 8in main. It
became clear this was not large
enough, but demonstrated the savings
in not running the long pipe leg of 8in.

The second winter hire boiler was
a 1000kg/h unit and has become a
regular on site, providing an
economical solution. For the main
site, which had a 6000kg/h winter
load and 3000kg/h summer load,
Byworth proposed a pair of
3000kg/hr Yorkshireman2 trailerised
boilers on a long term basis.

Now in the third year of a five year
contract, PPG is delighted both with
the savings and the service it has
received from Byworth.
