Abstract. In this paper, the potential application of an organic Rankine cycle (ORC) for cogeneration in a cement plant is presented. Two ORC system configurations are considered. The first configuration is based on the waste heat recovery from the exit gases of clinker burning system. An additional heat source which is the solar energy was used for the second …
The plant consumes on average 6.365 million units (kWh) of electrical energy per month and all of which comes from the national grid. The demand is on average 9.7 MW (peak).
