| Abstract: | Based on the properties of silicon particles,bonding behavior of silicon particles on steel sample and filter screen was studied and deposition characteristic of silicon particles in flue gas was analyzed.The results shows that silicon particles are flocculent at normal temperature,and have a reunion feature.Bonding capacity of silicon particles on steel sample mainly depends on the roughness of steel sample.The fouling will be serious and mechanical vibration cleaning is proposed timely to make the heating surface clean in actual operation.Filter screen is easily to be blocked.High-speed air jet ash cleaning is ineffective,and ultrasonic cleaning is recommended. |
