A new combined desalination and power generation system using solar pond was presented in this paper and the principle of the new system was introduced. A new disc convergent-divergent nozzle was desgined and used in the simple reaction turbine. According to theoretical analysis of the thermodynamics process, the power production and fresh water rate were obtained at tapical parameters. To prove the feasibility of the principle a small experimental rig was set. After simple experiment it is found that the actual fresh water rate is a little higher than the theoretical value, but the actual power is too much lower, which means that the hot brine couldn't expanded insufficiently in the nozzle and the flow passage of nozzle needs to be improved farther to increase the power production. Also the other influencing factors should be considered such as the condenser efficiency, drag losses,chamber pressure and etc.
