焦载热部分气化燃煤联合循环系统性能分析

文中提出的一种新型燃煤联合循环发电技术，载热部分气化联合循环技术，经近几年的研究及运行实验，得到不断完善。最近，作为这种系统的改进型式－－焦载热部分气化联合循环已被提出，其焦载热炉及气化炉部分已在清华电厂投建，并进行冷态调试。本文在载热循环基础上，通过改变煤成分等参数对焦载热系统进行分析，得出结论认为煤气质量及流率的影响对整个整合循环系统极为关键。

Performance Analysis of a Coke Carried Heat Partial Gasification Coal fired Combined Cycle

eat carried partial gasification combined cycle pertains to a novel coal fired combined cycle based electrical power generation technology developed by the Thermal Energy Department of Tsinghua University. As a result of continuous study over the years and the operating experience accumulated therein the said technology has seen significant improvement. Recently, as an improved version of the system, coke carried heat partial gasification combined cycle has been proposed and the coke carried heat boiler and gasification boiler have already been built at the Tsinghua Power Station with a cold state commissioning test performed. On the basis of the heat carried cycle and by changing gas components and other parameters an analysis is conducted of the coke carried heat system, which enables the authors to make the conclusion that the gas quality and flow rate play a key role in ensuring the high performance of the combined cycle system as a whole.
