Characteristics of an Ammonia-Water Mixture Turbine System with Low Temperature Heat Source
Details
This paper presents an experimental investigation on effectiveness of the AWM (Ammonia-Water Mixture) turbine system to the lower temperature heat sources. The system features two subsystems: a distillation/condensation subsystem (DCSS) and a vapor generator subsystem (VGSS). The experimental result and calculation results show that DCSS functions when the heat source is higher than 100 [℃], and VGSS functions when the heat source is over than 180 [℃]. Since the main application of the AWM turbine system is the heat recovery and there are abundant 100-200 [℃] exhaust heats as unused heat sources, effectiveness of the system to the lower temperature heat source, especially from 100 to 200 [℃], is very important. The experiment was carried out with changing the back pressure of the steam turbine.
