摘　　要：锅炉汽包水位是现代电厂锅炉安全运行的重要监控参数。本文在综合分析了以往汽包蒸发区数学模型的基础上,针对锅炉蒸发区的特点,依据质量和能量平衡,建立了汽包水位非稳态数学模型,并提出了水位控制的方法,对汽包锅炉的安全运行和控制具有参考意义。The drum level is an important monitor parameter on the safe operation of boiler in present.This paper concluded mathematical models of evaporation area in boiler in past papers.According to the characteristics of the evaporation area,a mathematical modeling based on mass and energy balance was developed under unsteady state.From the research,the method of level control was proposed,and the conclusion has reference value for the safe operation and controlling of steam boiler.
