Abstract :

Background and objective: CO2 originating from the combustion of fossil fuels will cause the greenhouse effect. Therefore, it is necessary to control it in production cycles, which are one of the most important factors of CO2 emission. In this research, by simulating the newly invented Allam cycle and creating a hybrid cycle based on Allam, CO2 produced in the Allam cycle is used as the working fluid, and in addition to reducing pollution, waste energy in the Allam cycle is used as an energy supplier. Two cycles of medium temperature and low temperature will be used. Reducing energy loss by creating a new foundation combined cycle will lead to an increase in the LHV efficiency of the power plant and as a result reduce global warming and environmental hazards. Material and Methodology: Using Thermo‌‌flow software, the Allam cycle, organic Rankine and also Steam cycle was simulated. Then the mentioned cycles were combined to reduce energy loss and the results were analyzed by Thermo‌flow and Excel software. Findings: The simulated combined cycle increased LHV by 0.5% Compared with the Allam cycle.   considering the energy loss by the components in the Allam cycle, and then creating a combined cycle, the LHV will increase by 0.98%. Discussion and Conclusion: The creation of the combined cycle led to the reduction of energy loss in the system. CO2 produced in the power plant is contained in the system also by examining the environmental conditions of the power plant and increasing the pressure to 1.127 bar, relative humidity of 0.1, and temperature of zero degrees, it will increase the LHV efficiency of the power plant. Increasing power plant efficiency, reducing energy loss and CO2 absorption will all lead to a reduction in global warming and environmental protection.
