摘　　要：由于THERMOFLEX对热力发电厂和IGCC电厂模拟具有实用方便的优点,因此采用THERMOFLEX软件建立了几类典型气化炉的仿真工艺流程,包括Shell气化炉、Texaco气化炉、E-gas气化炉和U-Gas气化炉,并基于实测工业数据设置相应的仿真气化条件,将各类气化炉的主要合成气成分和比例与工业数据对比分析,逐一验证了每一气化炉仿真模拟结果的准确性。以此为依据,针对同一设计煤种,仿真研究了6种现有气化技术,着重分析对比了它们的主要气化性能指标,并论证了它们用于IGCC系统时的优劣所在,为整体优化IGCC系统奠定了基础。In this paper, due to the convenience of the THERMOFLEX platform in thermal and IGCC power plant simulations, the models ate built on the platform for several types of gasifiers including the Shell, Texaco, E-Gas and U-Gas ones. Based on the measured industrial data, the gasification conditions are set for simulation. Through the comparison between the composition of the synthetic gases and the industrial data, the simulation results of the gasifers are validated one by one. Then, the simulative study on six gasification technologies is carried out using the same designed coal. The study conducts the comparison of the main gasification indices between the technologies and analyzes their pros and cons when being applied in the IGCC system. The study results lay a foundation for the optimization of IGCC systems.
