A traditional generator transforms the chemical energy that exists in fossil fuels (diesel, gas, biogas, among others) into electrical energy. Generally, its yield does not exceed 45%, but is somewhere between 35% and 40%. The remainder is released into the atmosphere in the form of exhaust gases.
A cogeneration system, on the other hand, is based on the use of heat, which raises the overall yield of the group to values between 75% and 90%. The use of thermal energy avoids major energy losses and provides greater efficiency and economic profitability to these projects while reducing the emission of toxic gases into the atmosphere.
The generating sets based on this different concept of energy generation naturally present some particularities:
