摘要: 电站锅炉超超临界二次再热技术不仅能提高机组热效率、具有良好的环保效果,并且是一种较为高效、低污染的成熟燃煤发电技术。目前国内超超临界锅炉热力计算基本采用国外引进的“黑箱”式计算程序,专用性强,功能适应性窄。基于J2EE标准的多层架构体系,提出“统一汽水流程”迭代的超超临界二次再热锅炉机组热力性能分析计算的通用模型及总体算法,完成针对锅炉不同类型受热面布置及工质流程顺序的热力性能计算系统研发。同时,结合某台百万千瓦级超超临界二次再热锅炉热力校核计算的实际应用案例,验证本文模型算法的有效性。

Abstract: The double-reheat technology for ultra supercritical boilers can improves the thermal efficiency of the unit, and has good environmental effects as well. At present, the introduced‘black box’ computational program, which has narrow and specific adaptability, is adopted in the domestic thermodynamic calculation of ultra supercritical boilers. In this paper, based on the multi-layer architecture of J2EE standard, the general model and the overall algorithm using unified steam and water flow circuit is proposed to calculate the thermal performance of the double-reheat ultra-supercritical boiler. And the thermal performance calculation system is developed to support different series of heating surfaces and flow sequential structure. At the same time, the effectiveness of the algorithm is verified through an application case of a 1 000-MW ultra-supercritical double-reheat boiler.

Key words: ultra supercritical boiler, double-reheat, thermodynamic calculation, unified steam and water flow circuit, J2EE architecture
