CTM Ambiente has designed and implemented the supply of six complete air intakes for the Rumaila combined cycle power plant. Each gas turbine has a power of 180MW. The first unit was synchronised with the Iraqi national network on 9 June.
Rumaila power station is located in the proximity of the city of Basra, in southern Iraq, in one of the most sandstorm-exposed areas of the planet.
The air intake is a self-cleaning type with a pulse jet system with a pre-filtration section of accumulation type, to maximise the lifetime of high-efficiency filters.
The air flow rate is about 1,600,000Nm³/h for each unit.
The system includes two pre-filtration stages of accumulation with efficiency G3 and M6 according to ISO EN 779 and one stage of self-cleaning filters with efficiency F9 according to ISO EN 779.
The pressure loss is very limited because the filtration speed has been kept very low.
