Assessment of an integrated system with coal fired power plant for multigeneration

In this thesis, a novel multigeneration energy system was introduced based on a conventional steam power plant. This system consists of four sub-systems, namely, waste heat recovery system using organic Rankine cycle, vapor compression refrigeration system, thermal vapor compression desalination system and greenhouse heating system. Energy and exergy analyzes were conducted for defining the efficiency of the sub-systems and the overall efficiency of the multigeneration energy plant. In order to better understand the system performance and to demonstrate the potential for improvement of the multigeneration system, exergoeconomic and environmental analyzes were also performed. The results revealed that the overall efficiency increased when a conventional steam power plant was converted into a multigeneration energy system. As a result, CO2 emissions were reduced because of the lower consumption of coal for the same amount of electricity generation. Fossil fuel consumption and global climate change increase the advantage and importance of an efficient multigeneration power plant.
