The Microwave Treatment System for Fly Ash Recycling in Circulating Fluidized Bed Boiler

摘要

Fly ash recycling system of the present design is anthracite coal combustion by using the fly ash containing much unburned carbon discharged from the electrostatic precipitator of the fluidized bed boiler recycle the heat generated by reheat via a microwave reactor to improve the efficiency savings coal combustion fluidized bed boiler relate to.; The subject innovation is provided a coal fired fluidized bed boiler, has a fly ash storage 24 in which the discharge of fly ash from the electrostatic precipitator (18) temporarily saved without being discharged to the time treatment plant (21), fly ash subjected to the fly ash storage 24 It is made, including the air inlet pipe 36 for introducing fluidizing air into the microwave reactor (26), wherein the microwave reactor (26).; The subject innovation with such a configuration, by recycling the fly ash to be disposed of and increase the thermal efficiency of the boiler, to reduce costs has the effect of improving productivity.
