燃油的闭式注蒸汽燃气轮机 (STIG)循环是一种高效率、低污染及少用水的新型动力循环 ,而燃煤气的闭式注蒸汽燃气轮机循环不仅具有注蒸汽燃气轮机循环的优越性能 ,同时可以实现煤的高效、清洁利用的目的 .给出了燃料改用煤气后 ,燃油的与燃煤气的闭式注蒸汽燃气轮机循环的性能比较 ,同时分析了两循环分别采用一次中间再热后 ,再热措施对两循环热效率的不同影响 .再热措施只有在初温较低、压比较高时才能提高IGCSTIG循环的热效率 ,而不象CSTIG循环那样 ,在所有压比范围内 ,再热均能使热效率有所提高 .
The closed-loop steam injection gas turbine (STIG) cycle is a new type of high-efficiency, low-pollution and water-less power cycle. The closed-cycle steam injection gas turbine cycle not only has the advantages of steam injection steam turbine cycle, To achieve the purpose of high efficiency and clean utilization of coal.Compared with the performance of closed steam injection gas turbine with fuel and gas when gas is switched to gas, The different effects of thermal measures on the thermal efficiency of the two cycles The reheat measures increase the thermal efficiency of the IGCSTIG cycle only at lower initial temperatures and higher pressure ratios and not at all the pressure ratios as with the CSTIG cycle Thermal efficiency has improved.
