The schematic diagram of the ORC test rig is as shown in Fig. 6. Thetesting rig is presented in Fig. 7.The evaporator transfers heat energy of waste heat source to theorganic working fluid and heats its liquid form into saturated gas orslightly superheated gas. The condenser transfers the heat of completedorganic working fluid from the turbine to the cooling water. This processcondenses the superheated organic vapor into saturated liquid orslightly subcooled liquid. In this platform, plate heat exchangers producedby SWEP (a company which professionally produces heat exchangersin Sweden) are used as the evaporator and the condenser. Thevolume of organic working fluid channel in the evaporator is2.13×10−3m3, and the corresponding value of in the condenser is3.25×10−3m3, as is shown in Fig. 8(a). The experimental systemadopts the GC-DRY-60 electric heating and heat transfer oil furnaceproduced by Yancheng Gongchuang Electric Heating Equipment Co.,Ltd. Following components are included in the facility, such as anelectric heater, a high tank, an oil temperature control system, a hot oilpump, a liquid level meter and other auxiliary fittings, as is shown inFig. 8(b). Its maximum heating power is 60 kW, and the actually-requiredheating can be adjusted by the temperature control system. Theworking fluid pump used in the experiment is hydraulic diaphragm typepump, JYMD-1000/2.5. Its major performance parameters are maximumflow 1000 L/h, maximum pressure 2.5 MPa, intake stroke 50 mm,and motor power 2.2 kW, as is shown in Fig. 8(c). The generator, themain facility for the electrical output of ORC system, is a three-phaseAC permanent magnet synchronous generator at high speed (with ratedpower being 5 kW, rated speed being 12000 rpm). When operatedunder rated conditions, the generator is with efficiency of 90%, and itsoutput voltage is proportional to the speed. The specially-developedreducer is used to adapt to the turbine and the generator. First-classgear transmission is adopted in the experiment, with a ratio of 5.304and an external dimension of 200mm×131mm×220 mm. The reduceris connected to the turbine through a coupling. Experimentalequipment consisting of a turbine, a reducer and a generator is shownin Fig. 8(d). The radial turbine used in the experiment is shown inFig. 8(e). The power of resistance wires is used as the load to consumeelectrical energy from the generator. The load can be adjustable, as isshown in Fig. 8(f).
