Aspekty energochłonności i obciążeń emisyjnych, występujące w obszarze układów kogeneracyjnych zasilanych biopaliwami

The article presents the conception and main model assumptions of a so-called agriculture-fuel-and-energy complex, which encloses the integrated production of energetic plants, bio-fuel, electric energy and heat. The paper also refers to the main theoretical assumptions and to the adopted methodology of energy and emission evaluation for the chosen example of a co-generation energy system conception fed by bio-fuel which Ms produced in the process of rape oil refining. The study ends with the presentation of chosen calculation relations regarding the energy input and the so-called "rate of return on CO2 emission" in reference to the individual stages of subsystems of the considered power engineering technology.
