摘要

以东方锅炉股份有限公司制造的超超临界1 000MW机组锅炉为研究对象

根据质量守恒定律、能量守恒定律和金属热平衡定律

构建了与其相对应的中间点焓值机理模型。在建模过程中使用集中参数分多段的方法

经过线性化、偏差化处理得到了相应的传递函数

将该函数转化为矩阵形式。该模型能够反映直流锅炉中间点焓值在一定工况下的动态响应特性。

Abstract

Taking an ultra supercritical 1 000 MW unit boiler produced by Dongfang Boiler Co.

Ltd as the object

the intermediate point enthalpy mechanism model was established

according to the mass conservation principle

the energy conservation principle and the metal thermal equilibrium principle.During the modeling process

the lumped parameter segmentation method was employed.By linearization and deviation

the corresponding transfer function was obtained and finally transferred into matrix forms.This mechanism mathematical model can reflect the dynamic characteristics of the once-through boiler under research conditions to a certain extent.
