As far as the distribution is concerned, a significant difference was found for the height analysis, where the greatest amount of tracer was found on the leaves placed in a high position.With regard to exposure, all the differences were significant, with the greatest amount of tracer being found on the best exposed leaves and the least on those in the interior of the vegetation. The anova test shows that the two tracers did not show significant differences between them while the factors taken into account do, which means that they can basically be used together without affecting the significance of the factors that do show significant differences between them.

These possible mixtures are also defined as an explosive atmosphere. To cause an explosion it is necessary the occurrence of a so called ‘trigger’, which can be for example: a spark due to production processes, a breakdown of the electrical system, an inconsiderate use of open flames or a hot surface in contact with the explosive atmosphere. In absence of such ‘triggers’ the explosive atmosphere is no longer a possible risk. As specified in the ATEX (Atmosphère Explosible ) regulation, the presence of ‘triggers’ is expressed on a probabilistic basis. For this probability evaluation, it is necessary to consider the overall available historical data and perform a statistical survey. The aim of this study was to discuss explosion prevention during biogas production and to determine if inside agricultural bio...

The aim of this study is the characterization of the emissions in small-scale fixed-bed pellet boiler (heat output of 25 kW) of beech and corn, and of its potential reduction to an addition of calcium dihydroxide. In the biomass combustion test 7 fuel mixtures were investigated with regard to the particulate content (PM10), gaseous emissions and combustion chamber deposit. The corn kernels tanned with calcium dihydroxide determined a decrease in particulate emissions (54 +/- 13 mg MJ(-1)) in comparison to corn, whereas in the combustion of corn pellet with 1% calcium dihydroxide high emissions were observed (193 +/- 21 mg MJ(-1)). With regard to SO2 emissions, the combustion of corn with the additives make a reduction in comparison to additive-free corn.
