Gas turbine inlet air is filtered in multiple steps. First, the filtration step is used
for removing the big things. Then, Sand and dust are removed using the inertial sand
separators. Sand separators filtration system is composed of 30 rows of the inertial sand
separators on 5 floors. In this paper, one floor of the inertial sand separators filtration system
of Shahid Kave power plant has been simulated using Ansys Fluent 16. A computational
server with 20 processing cores and RAM of 120 GB was used to carry out the calculations.
The velocity and pressure fields have been studied and the effect of density and diameter of
particles on inertial sand separators efficiency are investigated. Particle diameter and density
are varied between 0.1 to 100 micrometer and 500 to 2000 kg/m3 respectively. The result
shows that the collection efficiency of the inertial sand separators was reduced by increasing
the particle diameter. However, the collection efficiency of the inertial sand separators was
improved by increasing the particle density. Also, a few particles are collected by inertial sand
separators, so that collection efficiency is less than 1%. Therefore, this system is inefficient
and not cost-effective and elimination of the system fans could reduce the energy consumption
of the gas power plant around 360 kW.
