چکیده مقاله:

Today, the discussion of energy and optimization of its consumption is one of the most important issues in the engineering sector. The use of cogeneration systems in the home sector is growing due to their ability to generate heat and electricity from a fuel source such as natural gas compared to conventional energy conversion systems as well as reducing the overall cost of energy due to higher energy conversion efficiency. In combined systems, the energy conversion efficiency increases by about ۸۰%. Considering the new discussion of CHP systems in the country and increasing the market volume by implementing a plan to target subsidies and increase the demand for the use of optimal systems in order to save energy, the use of new and scientific marketing methods to develop the application of these systems is inevitable. CHP systems, as new products, must have advantages over conventional systems in order to succeed in attracting customers and promoting in the consumer market. In these systems, energy efficiency increases significantly. In conventional systems, ۲% of the input energy is converted into useful energy. This rate reaches ۴۰% in combined cycle power plants. Due to the energy crisis, increasing energy demand and the need to reduce environmental pollutants, the study of cogeneration systems and the use of on-site production systems that can manage energy consumption is recommended. CHP is a system with high energy efficiency and, compared to power and heat generating systems, significantly reduces the amount of combustion products per unit of energy consumed. The performance of the CHP method usually slightly increases the local fuel consumption compared to a single heat generator such as a boiler, with the same output power but compared to fuel consumption, both electricity and heat generators separately will save about ۳۵% in consumption. In general, heat recovery from hot gases from gas turbines, even in areas where there is a gas network, has an economic justification. Considering the cost of gas input to power plants, the use of recycling boilers to provide heat is the first priority.
