Abstract:Rankine cycle systems,using steam as a working fluid,are not well suited to the recovery
of power fromheat sources in the 300–450 ◦C temperature range,such as internal combustion
engine exhaust gases,mainly due to the relatively large enthalpy of vaporization of water.Admitting
the steam to the expander as vapour approximately 50 per cent dry,would be preferable
but turbines cannot be used to expand vapours from this state.However,screw expanders can
operate well in this mode.It is shown that,apart from being environmentally benign and free
from flammability risks,a screw-driven wet steam cycle system can recover power from engine
exhaust gases,with comparable efficiencies to turbine-driven systems using organic fluids at a
significantly lower cost per unit output.

摘要：流体驱动的兰金循环系统,其实并不适合于300~450摄氏度热力资源的能源再生或再利用.以内燃机排汽系统为例：其关键问题就在于其蒸发过程的焓值相对较大,由于内燃机的运行特点,干蒸汽的含量在进入膨胀装置前通常都接近50%的水平,但是透平机在此系统中的运行工况却并不理想,远不及螺旋膨胀式.这就说明,姑且不论其易燃易爆的环境风险因素,螺旋驱动的湿式蒸汽循环系统可以从内燃机排气系统中获得足够的可再生能量,其工作效率堪比哪些使用流体介质,且以可接受的代价就获得单位输出量的透平机.
