Possibilities of Using Grape Marc for Making Fuel Pellets

Popis výsledku v původním jazyce

The paper called &apos;Possibilities of using grape marc for making fuel pellets&apos; is focused on the topic of efficient usage of grape marc as a renewable energy source. From a global point of view, grapevine pressings, a byproduct of the wine industry, present a significant source of biomass. The organisation Internetionale de la Vignet et du Vin (OIV) estimates that there are over 66.5 mil. tons of grapevines manufactured globally, from which 38 mil. tons in Europe. This means that only in European conditions, there are approximately 8 mil. tons of grape pomace produced. Empirical measurements took place in the years 2013-2015 at grape marc samples from viniculture subjects in the wine-growing area Morava. The results of this paper are divided into two main parts - grape marc usage for energy purposes and for pellet production. There was implemented a wide range of calorimetrical measurements of combustion heat and caloric power of grape marc in its original state, grape marc after seed separation (assumption of oil pressing usage), and in seeds themselves. The results indicate that the heating power varies between 16.07-21.14 MJ. kg-1. The highest heating power values were stated by seeds and grape marc in its original state. It could be presumed that the main reason is rather high oil component in grapevine seeds. Moreover, the measurement set was supplemented by results focused on grape marc usage for pellet production. Different proportions of dried grape marc combined with wine shoots and hay were used as the input materials. The measured values imply that the highest heating power (19.22 MJ. kg-1) was obtained from pellets composited from 60 % grape marc, 20 % wine shoots, and 20 % hay. Their apparent density is 630.9 kg. m-3. The produced pellets correspond with the norm CSN EN 15210-2 from the perspective of mechanical ruggedness.
