摘要
为使数值模拟计算能够尽可能地真实模拟炉内实际流动、燃烧与传热过程,为工程实践提供重要信息依据。采用哈锅CFD燃烧数值模拟技术结合相关受热面传热计算程序,以哈锅自主研发设计的1000 MW高效超超临界双切圆变压直流锅炉为研究对象,进行炉内全过程数值模拟计算,评估锅炉及关键部件的偏差情况,为高效超超临界机组运行性能优化提供参考依据。
In order to make the numerical simulation calculation to simulate the actual process of combustion and heat transfer in the furnace as far as possible, to provide important message for engineering practice basis. CFD combustion numerical simulation technology of Harbin Boiler Corporation(HBC) is combined with the heat transfer calculation program of related heating surface. Taking the independently designed and developed 1000 MW high-efficiency ultra-supercritical pressure converter boiler as the research object, the whole process of the numerical simulation calculation in the furnace is done to evaluate the deviation of the boiler and the key parts, to provide the reference for the operation performance optimization of high-efficiency ultra-supercritical pressure units.
