Mt Piper Power Station (MPPS) is a 1,400 MW power station located two hours west of Sydney near the NSW country town Lithgow. Since the commencement of operations in 1993 there have been ongoing failures in the fabric filter infrastructure, which has impacted the environmental efficiency of the fabric filter, increased maintenance requirements and subsequent operating costs. A review of the performance of the Howden fabric filter infrastructure located at MPPS, and subsequent application of findings to industry wide fabric filter infrastructure, is the focus of this dissertation.

Efficiency of dust removal, as described by Wang et al (2004), is the key consideration in fabric filter design and specifically the shaker drive crank assembly (SDCA), the major fabric filter component responsible for delivering forces to the filtration infrastructure. A series of studies undertaken by Dennis (1975) describe the correlation between the primary loading inputs, including; quantity of shakes per cycle, shaking frequency, shaking amplitude and fabric filter bag acceleration. Understanding the impact of these variables is critical to analysing the existing design and the development of any design recommendations.

To gain an understanding of the SDCA failures, an analysis of the proprietary design and associated design iterations was undertaken. This involved reviewing the fabrication and quality assurance process, the current maintenance regime and inspection of failed SDCA components. The various designs were then modelled with simulated loading applied. Following this assessment, a root cause of the failures along with contributing factors were identified and used as the basis for proposing design modifications and refinement to the fabrication and quality assurance process.
