摘要

为消纳更多的可再生能源发电

燃煤机组将长期处于低负荷和变负荷瞬态过程

使得机组运行效率低且锅炉尾部受热面硫酸氢氨沉积现象加剧。本文建立了耦合余热回收系统的燃煤机组动态模型

获得了瞬态过程硫酸氢氨的沉积规律

提出了变负荷过程硫酸氢氨沉积优化控制策略。结果表明:在75%THA~50%THA变负荷过程中

采用优化控制策略后可以避免空气预热器转子热段发生硫酸氢氨沉积现象

同时将锅炉排烟温度控制在合理的范围之内;在降负荷和升负荷过程中

采用优化控制策略后空气预热器硫酸氢氨沉积Radian数累计值分别可减少2 100和29 600。

Abstract

To accommodate more renewable energy power

coal-fired power plants operate under low-load and transient load conditions for extended periods

resulting in low operational efficiency and intensified ammonium bisulfate deposition on the back-end heating surfaces of boilers. Dynamic models of the coal-fired power plant coupled with waste heat recovery system were developed to investigate ammonium bisulfate sulfate deposition behavior during transient process

and an optimized control strategy for load-varying operations was proposed. Results show that during load variation process from 75%THA to 50%THA

the proposed strategy can avoid the deposition of ammonium bisulfate sulfate in the hot section of the air preheater rotor

while maintaining the boiler exhaust gas temperature within a reasonable range. Furthermore

during the process of load reduction and increase

the cumulative deposition Radian number of ammonium bisulfate sulfate deposition in the air preheater is reduced by 2 100 and 29 600

respectively.
