Cardiff
University’s bioscience
department has
two gas-fired
steam boilers,
which were
installed in 2003
with standard
on/off burners.

One runs continuously; the other
operates on-demand. Together they
raise steam for autoclave sterilisation
services and supply-air
humidification for research facilities.

To improve steam quality and
boiler efficiency, original supplier,
Fulton installed a prototype
modulating burner on the primary
60J boiler. Following a 12-month
trial period, the revised burners have
passed with flying colours.
