Abstarct: In recent years, population growth and community development have increased the volume of waste in many parts of the world, including in Iran. If management measures do not reduce the amount of waste at the surface of the earth, the problem of increased waste will become a major and serious threat to human life Also, the access of developing countries to a variety of new energy sources is critical to their economic development And new research has shown that there is a direct relationship between the level of development of a country and its energy consumption From another perspective, each energy has its own characteristics in terms of manufacturing technology and exploitation, technical features, accessibility, geographical distribution, and other features Therefore, the diversity of the use of various energies, including waste energy, will place the country in terms of energy supply in a more secure position, and for this purpose, waste incineration plants were constructed that, in addition to reducing waste and generating power, could lead to a system of electric power generation, Heat and cold Accordingly, in the present study, the research is baxsed on the fact that after measuring, studying and studying the smoke from the garbage plant, which has a significant thermal potential, can be used in the system for generating electricity, heat and cold Using the Aspen software, an initial model of the Triple Combined Cycle Power Plant was designed to accommodate the layout and arrangement of the simultaneous production cycle at the waste incineration plant After exiting the combustion gases from the boiler, part of the exhaust fumes is introduced into a heat exchanger designed to provide heating After exiting the combustion gases from the boiler, part of the exhaust fumes is introduced into a heat exchanger designed to provide heating The design of the heat exchanger according to the requirements of the power plant is done using the EES software, and the heat exchanger efficiency is 70% changed with the change in the amount of fuel, as well as the temperature of the water introduced into the heat exchanger is 35 ° C and the water outlet temperature 70 ° C with a flow rate of 5 kg / s, which can be changed by changing the fuel ratio parameter Another part of the exhaust fumes is to provide cooling for the use of absorption chillers. Due to the low temperature of the exhaust gases, an ammonia-water adsorption chiller is used to reduce the need for users to cool down at a lower temperature Absorption chiller modeling was performed using EES software. After calculating and modeling the cooling value created in the absorption chiller, the first evaporator was 1111 kW and the second evaporator was 529 kW. The temperature of the exhaust gases after cooling and Heating is 120 ° C and then passed through the filters to the environment The efficiency of the power generation cycle is 35% and the exergy efficiency of 28%, which increases the efficiency of the simultaneous production by 70% during the conversion of the plant to a simultaneous production system (CCHP). As a result, the economic justification of the current plan is done using Excel software and the return period is estimated at 5 years However, simultaneous production systems an important role in energy efficiency, as waste is increasing daily, In this research, the heat and venting of the waste incineration plant in the production system are used in order to utilize the outlet smoke and heat of the garbage power plant in the production system simultaneously can be an innovation in the present research.
