Experimental Study on Combustion Behaviors and Carbon Monoxide Emission Characteristics of Single Coal Pellets

1 The aim of this study was to evaluate the toxicological influence of tobacco smoke on fertility and reproduction of Wistar female rats. The influence of tobacco smoke from the Polish ‘Popularne’ cigarette brand was studied. The experiment was conducted on three generations of animals, each generation having two litters. The initial number of animals of the parent generation FO was 192 (128 females and 64 males). Animals were passively exposed to tobacco smoke in three different concentrations based on the content of carbon monoxide (500, 1000 and 1500 mg of CO per cubic meter of air). Animals were exposed to tobacco smoke for 6 h a day, 5 days a week, during 11 weeks. 2 The analysis of indices of mating and fertility revealed the decrease in those indices with animals exposed to tobacco smoke. We also observed an increased number of mothers breading among animals exposed to tobacco smoke. In animals exposed to tobacco smoke, the dose-effect or dose-response dependencies for mating, fertility and delivery indices were found. There was no influence of tobacco smoke on the duration of pregnancy. 3 Tobacco smoke inhalation caused increased levels of carboxyhaemoglobin. 4 Tobacco smoke did not change the duration of pregnancy in rats.

Abstract The current study emphasis on the engine performance and emission characteristics of rapeseed and soya biodiesel dispersion on a novel nanocatalyst at different concentrations of 25 ppm and 50 ppm. The results of this study were compared with those of conventional diesel at varying load conditions on a combustion ignition engine. An α-Fe2O3-doped Al2O3 was mixed with rapeseed biodiesel and soya biodiesel using an ultrasonicator at a frequency of 25 kHz. This study revealed that the incorporation of nanoparticles in biodiesel enhanced the performance of the blends by reducing the content of lignin and other unsaturated fatty acids. The improvement in the performance of the engine is mainly attributed to the high area-to-volume ratio of the nanocatalyst. Emissions of NOx. hydrocarbon and carbon monoxide during the combustion reaction increased significantly when nanoparticles were added at higher concentrations. Contrastingly, the emission of NOx in pure biodiesel was higher than that in conventional diesel. The addition of nanoparticles reduced CO emissions due to the presence of extra oxygen molecules and converted carbon monoxide into carbon dioxide. Soya seed biodiesel blends with 50 ppm nanoparticles showed better engine performance and emission characteristics as compared with all other blends.
