中文摘要	介绍了由PG6581B燃气轮机构成的焦载热部分气化燃煤联合循环系统的结构和特点,并对PG6581B燃气轮机燃用中低热值煤气的性能进行了计算和分析。计算结果表明,燃用中低热值煤气后,PG6581B的功率与效率均有所下降,但在可接受的范围内。进一步分析后得出:降低煤气中CO2和N2等不可燃成分的含量,提高可燃部分中H2的含量可提高燃气轮机的性能。对该联合循环系统的初步计算表明,应用了PG6581B燃气轮机的焦载热部分气化燃煤联合循环系统的热效率可以达到42%以上。; The construction and features of a PG6581B gas turbine-based coke-carrying thermal partial-gasification coal-fired combined cycle system are described along with a calculation and analysis of the performance of the PG6581B gas turbine when firing coal gas of medium and low calorific value. The results of the calculation indicate that the output power and efficiency of the PG6581B will somewhat be reduced when firing the above-mentioned coal gas, but the reduction is within an acceptable range. A further analysis has revealed that by lowering the content of non-combustible constituents in coal gas, such as CO_2 and N_2 and by increasing the H_2 content in the combustibles it is possible to enhance gas turbine performance. A preliminary calculation of the combined cycle system shows that the thermal efficiency of the PG6581B gas turbine-based coke-carrying thermal partial-gasification coal-fired combined cycle system can exceed 42%.; 国家自然科学基金资助项目(50323002)
