Background and Objective: The purpose of this paper is simulationg of gasification and steam cycle of Tehran waste power plant in order to achieve and identify the parameters affecting the efficiency and output of power plant. The information obtained through this simulation, in addition to being used to increase the productivity and efficiency of Tehran power plant, can be used as valuable information in other waste power plants of the country should also be employed. Method: By considering the obtained data from Process Flow Diagram, actual operation condition of this plant, the analyses of Tehran’s urban waste and using Aspen plus software as the simulating and modeling tool. The developed simulation model has been validated by using actual operating condition of the plant and also the experimental results of the verified papers. Findings: The result shows that the moisture content and the composition of the inlet MSW have significant impact on the output power of this plant. The findings indicate that a 10% reduction in the moisture content of inlet MSW cause an increase of 30% in output power. Also, by increasing the wood and the green waste in the combination of inlet MSW, the output power will be reduced. Discussion and Conclusion: Generally, MSW has low thermal value due to its high percentage of biological ingredients. Therefore, identifying the factors which are affecting the efficiency and power output of the power plant is essential and important. In this regard, the simulation shows that the high percentage of wood-containing compounds and green waste in the input waste will reduce the output power of this plant. As a result, implementing necessary measures to reduce the amount of moisture content of incoming waste as well as achieving the combination with the least amount of wood and green waste will increase the efficiency and the output power of this plant.
