Service for the RAF
September 1st 2007 Wellman has received an order for
nine Ygnette hot water boilers for a
Royal Air Force base in the UK.
They will replace and upgrade
existing Wellman Robey Ygnette
boilers installed in 1977.
The new hot water boilers
consist of three 2500kW LPHW
(4.5bar g) and six 800kW LPHW
(10bar g) boilers, all with dual fuel
modulating burners from Wellman's
own burner company, GP Burners.
The Ygnette is said to achieve
high performance on all fuel types
and is of the horizontal three pass
wet back reverse flame designincorporating a large furnace within
which the efficient combustion of
fuel takes place. The design is said
to provide near perfect combustion
with maximum fuel use, high
operational efficiencies and low
running costs.
Modulating burner controls
improve boiler operation by
monitoring the water flow
temperature to produce a
continuous control signal that
determines fuel input. Benefits also
include higher turn down ratios. More articles from Wellman Robey: |
