Co-generation is the combined production of electrical and thermal energy.
Every day we use high-quality fuel (methane gas or diesel) to produce thermal energy and electricity with boilers, thermoelectric plants, taking it from the national grid. This involves a greater consumption of resources linked to the dual generation of energy.
Co-generation is the combined production of electrical and thermal energy. How is it possible?
An engine is connected to an electric generator that, by exploiting the mechanical energy developed by the engine, produces electricity.
As the engine runs, it generates heat as its cylinders and lubricant oil become hot and exhaust gases are produced. This heat, which is normally dispersed into the environment, is completely recovered. If we compare the generation efficiency, compared to the separate production of electricity in the thermoelectric plants and the heat in the boiler, we discover that co-generation has a fuel consumption that is 30-40% lower. This means lower costs and fewer emissions into the atmosphere.
Co-generation is particularly appropriate for all the areas where the contemporary thermal and electrical demand is generally constant during the year.
