Shaheen Aziz, Muhammad Ibrahim Pathan, Suhail Ahmed soomro


The fluidized Bed Combustion (FBC) technology is growing very fast. Due to its merits, first time this technology has been introduced in Pakistan by installing 3 × 50 MW power plant at Khanote. The (FBC) Power plant at Khanote, based on Lakhra coal has been facing operational & technical problems, resulting in frequent shut down of generation units, hence causing heavy financial lossed. This study reveals that due to the presence of high percentage of silica in lime stone supply, the generation tubes and wings / blades of Induced Draft Fan (IDF) were eroded, and filter bags were ruptured and resulting in frequently shut down of power generation units.
