Research On Reducing Wear For Easy Weared Parts Of The Recirculating Fluidized-bed Boiler Of Anyuan Power Plant

In ANYUAN power plant, The wearingof the metal parts such as conomizer and receiver, and wearing-resistant plastic able is one of the main reasons of bringing about move trouble as etube-burst production in the CFBB. The measures that easy wear parts to prevent grind in CFBB will directly affect the economic and safety move of the CFBB. In this thesis, by wearing experiment and thermal shock-resistant experiment, respectively constitute the main performance from experimental studies and comprehensive analysis。In ANYUAN power plant, Through comprehensive analysis and research, draws the conclusion that the main reason of boiler parts internal badly worn is the fly ash impact the lining and metal parts. Literature shows that wear rate connect with the destruction resistant strength grain size of ear-resistant material and so on. And effected wearing rate material factor:erode angle, erode speed, wearing medium hardness.After many experimental research and practice, The solution that boiler parts internal badly worn are for the different part of the furnace. The conclusion is:aiming at different parts wear in ANYUAN power plant, Should adopt different measures to Drop wearing, install surfacing in water-wall,fixing the abraseproof board in smokestacks,install surfacing in cooler serpents tube,add the measure set in one-level separator and install surfacing in the wind-cap,and so on. The wearing in nonmetal chooses wear-resisting plasticity silicon carbide instead of wear-resisting brick materials products. The practice proved that these measures greatly reduce parts wear in the Recirculating Fluidized-bed Boiler of ANYUAN power plant.The research and practice results indicate that, Reducing Wear is effective for Easy weared parts in the Recirculating Fluidized-bed Boiler of ANYUAN power plant. This technical modification measures run today, Effectively controlled the phenomenasuch as pipe explosion or stop the production, The research has brought huge economic effects for the ANYUAN power plant...
