Research on the pyrolysis and gasification scheme of coal-fired boilers coupled with wind turbine blades
摘要
Abstract
The"retirement wave"of wind turbines is approaching,and the harmless treatment of a large number of decommissioned wind turbine blades is an important bottleneck for the wind power industry to achieve a complete green closed loop.Under the background of the country's active implementation of energy conservation and carbon reduction renovations in coal-fired power plants,the co-processing of decommissioned wind turbine blades by coal-fired boilers can achieve the reduction,resource utilization and harmless treatment of solid waste.In response to the demand for large-scale continuous heat treatment of decommissioned wind turbine blades,a process route of coupling coal-fired boilers with pyrolysis-gasification of wind turbine blades is proposed.By extracting the flue gas from the boiler as the heat source for pyrolysis-gasification,the combustible oil and gas produced by pyrolysis-gasification are sent into the furnace for combustion,simplifying the processing procedure of wind turbine blades and reducing the initial investment.The process was simulated and verified by using Aspen Plus software.The results indicate that when the processing rate of wind turbine blades was 1 t/h,the proportion of flue gas extracted did not exceed 0.6%,thereby meeting the energy requirements for pyrolysis-gasification.A pilot-scale experimental study was conducted based on a 7 MW chain grate boiler,and it was found that when the oxygen volume fraction in the flue gas was 5%～10%,clean glass fibers could be obtained through"one-step pyrolysis-gasification".Based on both simulation results and experimental data,a flue gas conditioning-based integrated treatment process was proposed:control the flue gas temperature at 600～700℃and the oxygen volume fraction at 5%～10%by blending flue gas from the economizer outlet and adding air,so as to enhance the strength of the recovered fibers and further simplify the wind turbine blade treatment process,providing a reference for the large-scale treatment of wind turbine blades.关键词
