摘要/Abstract

摘要： 以概念设计的300 MW富氧燃煤锅炉烟气压缩系统为研究对象,采用集中参数法建立了烟气压缩机和烟气冷却器动态数学模型,并建立了相应仿真模型。在B-MCR工况下,进行了给煤机转速和烟气压缩机转速等扰动试验。结果表明:当给煤机转速扰动或烟气压缩机转速扰动时,烟气压缩系统各运行参数响应较为灵敏、变化幅度较大;而一次再循环风机挡板开度扰动和烟气冷却器冷却水阀门开度扰动,对系统各运行参数影响小,响应时间长。

Abstract: Taking the flue gas compression system in a 300MW oxy-coal fired boiler unit as an object of study by concept design, math model of gas compressor and gas cooler were established with the method of lumped parameter, and dynamic simulation of flue gas compression system was developed. The disturbance experiments on coal-feeder speed and flue gas compressor speed, etc. were carried out based on B-MCR stable condition. As a result, the operating parameters of gas compressor have a more sensitive response and larger change magnitude when the perturbation of coal feeder speed and gas compressor speed is disturbed; when the opening of primary recirculating fan damper and water valve of flue gas cooler is disturbed, the gas compressor operating parameters change less, and the response is longer.

Key words: oxy-coal fired boiler, simulation model, flue gas compression system, dynamic characteristics
