Description
This paper investigated the flow distribution and total pressure drop across a
designed 3-D filter housing integrated with a 3-stage filtration system using
computational fluid dynamics (CFD). The filter housing model was proposed
for a heavy-duty industrial gas turbine plant operating at an average ambient
temperature of 20°C.The pressure drops across the classes of filters were 652.8
Pa, 2692.2 Pa, 887.8 Pa, 776.2 Pa and 2304.2 Pa for I-GB, GB-GA, GA-FA, FAHA,
and HA-O, respectively. The results obtained indicated an acceptable total
pressure drop of 7.2% for the entire filter housing before filter clean-up.
Although the CFD simulation result shows that small outlet flow velocity and
transonic flows exist at the outlet of the filter housing, the designed filter
housing was proved compatible with the studied GT, for inlet flow conditions
between 600⩽W air⩽610 kg/s and 60⩽v air⩽70 m/s for the air flow rate and
velocity, respectively. Furthermore, the designed filter housing could be
adopted for the studied GT and locations of Usan and Maiduguri in Nigeria,
and other locations with similar environmental conditions.
