Abstract

This paper indicates the efficient use of fuel in producing both power and desalted water by a cogeneration power-desalting plant as compared to separate desalting and power plants. The second law of thermodynamics efficiencies of a boiler driving a desalting plant separately, a boiler of a dual purpose plant, and a dual purpose plant as a whole were calculated. Typical reference desalting and steam power plants of modern practice were given to show their performance and fuel consumptions in both separate and combined arrangements. The available energy consumption and second law efficiency were used for rating the desalting plant and the dual purpose plant, respectively. These rating methods proved to be more realistic than other rating methods (ie., performance ratio, gain ratio for desalting plants and first law efficiency and utilization factor for dual purpose plants).
