Investigation of Thermal Desalination System Using Heat Recovery

摘要

The work presented in this paper is an attempt to investigate the performance of thermal desalination system using heat exchanger. Helical coil heat exchanger has been used as a condenser to condense vapors passing over the coil where cooling water in the coil absorbs latent heat of condensation as well as sensible heat of vapors. Experiments were conducted for different initial temperature of water. Results have shown that application of a separate condenser for thermal desalination system augments rate of distillate output. Condenser also performs the function of heat recovery. In present work, heat recovery has augmented distillate output by 50%. Use of warm water for desalination improved vapor generation and its temperature. This has improved heat recovery of the system.
