Dynamic Modelling, Simulation and Analysis of HRSG of Energy Island System

Energy Island System (EIS) is a kind of high energy use and wide development prospect energy supply system that integrates cooling, heating and electricity generation with the energy being used step by step. HRSG is the main equipment to realize the heat reuse of gas turbine whose properties and parameters greatly affect the performance of other equipment and even the whole system. In this paper, the basic working principle of EIS and the working flow of HRSG were introduced, and a dynamic model of HRSG is established on the base of the law of conservation of mass, momentum, energy and so on. The structure and modules function of the simulation system was given after the comparison of the results of experiment and simulation system, and the simulation model proved reliable.
