摘要
循环流化床燃烧是一种高效、低污染、燃料适应性广的洁净煤燃烧发电技术, 在
当前及今后仍以燃煤发电为主的情况下,循环流化床燃煤发电技术将在国内外得到
迅速发展。本论文基于实际使用的循环流化床锅炉作为仿真对象,结合循环流化床
锅炉燃烧室和实际机组工艺流程工作特点,以燃烧室静态和动态特性研究为目的,
借助一体化图形建模实时仿真支撑系统,在研究燃烧室内燃烧、换热、流动机理基
础上,建立了燃烧室通用算法,借此开发了循环流化床锅炉燃烧室仿真模型,并对
仿真模型有效性进行了验证。随着我国环保法律和法规的健全与实施,对火电站的排
放要求在不断提高,监督力度不断加强,大型 CFB 锅炉在我国电站中的应用也将越
来越普遍。仿真结果表明,所建模型能够正确地反映循环流化床锅炉燃烧室的动态
特性。该模型为大型循环流化床锅炉燃烧室的设计、运行等提供了一个简便、快捷
的试验工具。

Abstract
Circulating Fluidized Bed (CFB) combustion is a new technology of coal cleaning
combustion and will have a great development in all over the world due to its many
merits. This paper takes CFBB which has characters of external exchanger as simulating
object. Combined with practical units technics process bustion chamber working
characteristic, in order to study the dynamic and static characteristic bustion
chamber , in virtue of graph modeling real time simulating support system, on the base of
study of inner burning bustion chamber, exchanging and flow mechanism, we
build general arithmetic bustion chamber, and through which to develop CFBB
combustion chamber simulating model, and to give a validation of the validity of
simulating model. With the development of supervision mechanism and implementation
of stricter environment protection rules and laws, it can be imagined that the large-scale
CFB boilers will be more widely results of simulating shows that this model
can reflects correctly the dynamic characteristic of bustion chamber. This
model afford a convenient and shortcut examination tool for the designing and running of
bustion chamber.
