Waste heat recycled
March 1st 2008 When budgeting a project to
supply steam at 15 tonnes
per hour it would not be
unusual to plan spending of
upwards of 500k for run and
standby boilers, ancillary equipment
and installation costs. Additionally
fuel costs to run the plant for the
just the first year could be up to
£1m depending on the load pattern.
Faced with a similar project,
Chris Payne of Wessex Incineration
Co looked for a more
environmentally and financially
sound solution. Its new processing
plant had a steam requirement of
15 tonnes per hour at 10 bar g
working pressure, but they knew
existing plant was already
producing heat which was
dispersed to atmosphere.
Chris commissioned Byworth
Boilers to design and manufacture
a boiler to use this waste heat to
satisfy the steam demand. As all
waste heat applications are unique,
this type of boiler has to be
individually designed to achieve
optimum performance. Byworth's
chief designer John Fox, designed
a two pass boiler around 3 meters
in diameter and with a working
weight of almost 65 tonnes.
Operating purely on the waste
heat from the existing process, no
fuel is consumed, running costs
are minimal (routine maintenance
and negligible electricity), and the
carbon footprint is excellent.
Waste heat boilers can be utilised
in a range of situations where heat
is an end product of a process.
They are commonly used in
combined heat and power
projects, and are equally suitable
for steam or hot water production. More articles from Byworth Boilers: |
