Preventing filter ice-up
May 1st 2009 Infrared heaters from Heraeus
Noblelight are being used to prevent
filtration systems from icing up
within an acoustic protection system
for a large scale (inline) gas
compression station in Germany.
Silencing systems for gas turbine
power plant typically handle gas
pressures to 2000bar, with exhaust
gas temperatures of about 500°C. It
is important that intake air to turbines
and compressors is filtered and that
filtration systems do not ice up.
Three systems, each comprising 12
fast response medium wave, 5.6kW
infrared modules, were specified and
installed for various filters. These are
arranged in three banks of four
emitters and are controlled by a
thermostat, which switches on the
heaters when the temperature falls
below a set level and switches them
off when the temperature rises to a
pre-set level.
Use of gold reflectors is said to
enhance the efficiency of infrared for
this application. More articles from Heraeus Noblelight Ltd: |
