摘要
为提高超临界直流锅炉启动过程中疏水热量的回收效率,设计“分质回收+多级利用”的热量回收方案,采用多阶段能量梯级利用的能量回收策略和分层控制、预测优化的控制策略,实现能量利用效率最大化。通过数值仿真与实验验证方案性能,结果表明,该方案能够显著提升热回收效率和运行稳定性,同时具备较高的经济性和工程可行性,可为能源高效利用提供了可靠支持。
To enhance the recovery efficiency of hydrophobic heat during the start-up process of supercritical direct current boilers,a heat recovery scheme of“differentiated recovery+multi-level utilization”is designed.A multi-stage energy cascade utilization energy recovery strategy and a hierarchical control and predictive optimization control strategy are adopted to maximize energy utilization efficiency.The performance of the scheme was verified through numerical simulation and experiments.The results show that this scheme can significantly improve the heat recovery efficiency and operational stability,and at the same time has high economic efficiency and engineering feasibility,providing reliable support for the efficient utilization of energy.
