Cogeneration systems

Cogeneration can be defined as the general production of thermodynamic heat and electricity from a single initial source of energy. The device, in which the process of cogeneration occurs, is called cogeneration device. Cogeneration changes separated electric energy and heat production. The separation of electric energy and heat production is characterized by substantial energy losses of initial fuel. In the separated power generation, the user receives the electric energy, which is produced by the large-scale power plants and heat is produced in high-efficiency boilers. In this case losses make about 40% in produced heat and 60% – produced electric energy.
