电站锅炉燃烧系统和蒸发系统仿真模型的建立

目前用于仿真目的的电站锅炉系统的燃烧模型普遍采用零维稳态模型 ,炉膛水冷壁模型采用集总参数模型。在现代仿真系统在某些领域的高精度要求的前提下 ,如果仍采用上述方法就不能满足需要。因此该文在建立精确的模型方面做了崭新的尝试 ,燃烧系统采用一维的燃烧模型 ,水冷壁就采用分布参数模型。虽然增加了方程的数量 ,但仍能满足实时仿真的需要。图 5表 2参 5

A Simulation Model for Combustion & Evaporation Systems of Power Plant Boilers

At present, zero dimension stationary models are generally used for the simulation of combustion systems of power plant boilers and lumped parameter models for the water cooled walls of the furnaces. But high precision requirements of present day simulation systems can not to be satisfied if such simulation methods were still to be used. This paper presents a novel attempt of formulating a precise model, where the combustion system is modeled one dimensionally and the water cooled walls spatially. Though the number of equations have increased, real time simulation requirements can still be met. Figs 5, tables 2 and refs 5.
