Study of the Use of Bag Filters in Hot Gas Filtration Applications, Pilot Plant Experiences
A complete experimental campaign has been carried out in a hot gas filtration test facility so as to test different types of bag filters. The facility is designed to operate under a wide range of conditions, thus providing an excellent tool for the investigation of hot gas filtration applications for the conventional and advanced electrical power generation industry such as IGCC, PFBC or fuel cell technologies. Relevant parameters for the characterization and optimization of the performance of the filters have been studied for a variety of operation conditions such as filtration velocity, particle concentration, pressure and temperature among others. Pressure drop across the filter, cleaning pulse interval, baseline pressure drop, filtration efficiency and durability of the filter have been investigated for each type considered and dependences on parameters have been established. On top of that, optimal operating conditions and cleaning strategies were determined. The tests results show that bag filters are a suitable alternative for the hot gas particle removal due to the better performance and the high efficiency observed, which makes them suitable for industrial applications operating under high temperature and high pressure conditions considered within the study (200℃-370 ℃ and up to 7.5 barg). Additionally, a technology based on combined dry removal of particles and SO2 in a single step by using a high temperature filter unit and solid sorbent injection for large coal combustion power plants is proposed to be studied in this paper.
