In the power generation industry an uninterrupted supply of power is critical and maximum reliability is essential. Freudenberg filter systems are optimally designed for requirements in regions coastal, onshore, and anything in between.
For gas turbines and compressors of power plants near the coast or located onshore, two-stage filter concepts generally achieve ideal results. The first filter stage is typically equipped with pocket filters, the second with cassette filters. Particles and moisture will never have a chance. With a three-stage system, it is even possible to achieve EPA purity level.
Power plants for generating electricity situated near deserts are subject to particularly adverse environmental conditions such as high dust loads from desert storms, or high morning humidity. These factors influence the selection of a suitable intake air filter system.
The correct selection of filter cartridges has proven to be an effective barrier. A cylindrical/conical set, for instance, can be operated with optimized pulse-jet cleaning and depending on the requirements, are available in EPA filter classes.
Inadequate filters in power plants endanger process reliability. If turbines fail, this quickly leads to bottlenecks in the power supply. Filter solutions from Freudenberg Filtration Technologies are making two power plants in Ratchaburi, Thailand both more reliable and more powerful.
A coastal power plant in Saudi Arabia was equipped in a first phase with conical-cylindrical cartridges for intake air filtration. In phase two, one test unit was converted to GTS double-cylindrical design. This proved to be very successful in terms of filter lifetime, reduction in overall pressure drop and turbine power output, so that all units will be converted to the double-cylindrical concept. Evidence showed that harsh environmental conditions with sandstorms could not affect efficiency.
