Abstract

A high temperature gas cleanup system which consisted of three cyclone separators in series, has operated satisfactorily through 500 hours in a 1 Mwt PFBC pilot test unit. The fly ash concentration in cleaned gas stream reduced to values below 2 ×10-4kg/m3and there are no particles larger than 10µm. The second stage cyclone is the newly developed Φ240mm PV type cyclone separator with dimensions optimized. Its measured particle cut size is 1.2µm and the resistance coefficient considering pressure drop about 12. The third stage multicyclone separator consists of three Φ100 EPVC-I type cyclone tubes and its collection efficiency of 8µm particle is about 99.5%.
