The main problems existing in a CFB boiler were mainly shown in the following aspects: The water wall at 2.5 m above the dense zone was seriously worn

the main performance in the furnace left and right wall near the center of the furnace transition zone water cold wall. The power plant completed the renovation of the water wall in the transition zone of the CFB unit in 2013. The main measures were as follows: used the technology of anti-friction beam and metal anti-friction baffle

and improved the design and sealing of the anti-friction baffle. Optimized the spacing of anti-friction partitions. The results show that: the abrasion of the water wall in the transition zone is effectively controlled

and shutdown of the unit due to abrasion of the water wall in the transition zone has not occurred. The method can be popularized on the same type of CFB boiler.
