With the exhaustion of fossil energy sources in sight, the importance of the renewable sources of energy becomes one of the major conditions for permanently sustainable development not only in agriculture, but also in the society as a whole. The growing use of biodiesel has opened other areas of utilising the by-products from the manufacture of rape seed oil methyl ester (FARME) as an energy source, used in the combustion equipment designed for these alternative fuels. The aim of this paper is to assess the feasibility of utilising the by-products from the production of rape seed methyl ester as a source of energy, from ecology and economy aspects of the combustion equipment used. Therefore, the study is focused on the concentration of emissions generated by burning FARME, and distillation of residuals from FARME production plants. An important objective of this study lies in the determination of the stoichiometry characteristics of rape seed oil methyl esters and distillation residuals from FARME production plants. The following parameters are set by calculations: fuel heating power, oxygen amount (air) necessary for ideal combustion, flue gases amount and composition, and flue gases specific weight.

Keywords: rape seed oil methyl ester; FARME; a liquid fuel; stoichiometry; combustion equipment; emissions; heating value; caloric value
