Within the primary aluminium smelter, the spatial requirements and capital cost of the GTC remains a major challenge. Due to its large size the CAPEX is predominantly determined by the mass of steel required. A partial solution to reduce footprint and steel weight is to increase the size of the filter modules while subsequently reducing their quantity. Unfortunately this method of footprint reduction is limited by N-1 baghouse flow conditions — the increased filter velocities with one module out of service.Danieli Corus has addressed this limitation in the new compact GTC design where the low pressure filter cleaning system accommodates longer filter bags. In addition the Danieli Corus compact GTC design is configured with a standby module and exhaust fan thereby avoiding the increased flow associated with N-1 conditions. The new configuration is narrow so it can easily be situated in the courtyard which is often congested with roadways, storage silos and material handling equipment.There are simplistic advantages to the new configuration which result in a decrease of 15% in the steel weight and overall CAPEX reduction of 10% from traditional Danieli Corus design.
