双炉膛直流炉蒸发系统的分布参数建模
Modeling distributed parameters in evaporation system with twin-furnace once-through boiler
摘要
Abstract
Model of non-uniformly distribution in two-dimensional surfaces of water-wall tubes was established by the real-time 3D temperature distribution, and the variation of evaporation system with distributed parameters in a twin-furnace once-through boiler was determined by using the visualization of monitoring combustion.The imaginary wall surface was put forward to simplify the twin-furnace problem, and the correctness of the method was proved by the simulation.The results show that the metal temperature close to the twin-furnace is higher than that close to the edge which is consistent with measured data, and the maximum relative difference is 8.56％ at 90％ BMCR (boiler maximum continue rate).It is suggested that the theoretical results agree well with the operating status of power plants.关键词
