摘要

开发了一种用于分析空气/气体系统动力学的计算机模型。一组通用元件通过通用结结构相互连接,以表示各种系统配置。然后,根据广泛的流体、热和机械干扰,确定系统中任何点或站的压力、流量、温度和传热率的响应。该模型已用于火电厂炉内爆分析。建立了一个燃煤电厂模型并进行了仿真。炉内压力漂移的模型模拟结果与现场试验数据吻合较好。

Dynamic Modeling and Simulation of Gaseous Systems
A computer-based model for analyzing air/gas system dynamics has been developed. A set of generic elements are interconnected by generalized junction structures to represent a variety of system configurations. The response of pressure, flow, temperature and heat transfer rate at any point or station in a system is then determined due to a wide range of fluid, thermal and mechanical disturbances. The model has been used to analyze furnace implosions in fossil fuel power plants. A coal-fired plant model has been constructed and simulated. The model simulations of the furnace pressure excursions are in close agreement with the data from the field tests.
