AB  - The aim of the article is to show the effects of the main air plasma gasifier operating parameters, such as temperature and equivalence ratio on the gasification performance of sewage sludge from wastewater treatment plants. The parametric study was performed using a one-dimensional mathematical model to determine the equilibrium composition of the system. The model is based on the principle of the minimum of the Gibbs function and uses only the ultimate and proximate analysis data as input to the model. The output of the model gives the equilibrium composition of the gasses produced. The parametric analysis was performed in order to determine the optimal operating parameters of the plasma reactor in order to obtain syngas with the highest heat value while achieving the maximum efficiency of the process. The collected results can be useful in further analysis of the gasification processes in plasma reactor, such as exergy analysis and kinetics.

AB  - Elevated concentrations of heavy metals in water can cause deformities of the mouthparts in chironomid larvae reared on artificial sediment. This investigation is an attempt to study effects of increased copper concentrations on mouthparts deformities of Chironomus plumosus larvae reared on natural sediment obtained from carp pond. Since the bioavailability of heavy metals is greater in artificial substrates than in natural ones usage of carp pond sediment, especially due to its low heavy metals content according to sediment quality guidelines, should provide more realistic assessment of biomarker potential of chironomid mouthparts deformities in biomonitoring of copper sediment pollution. It is demonstrated in the experiment that an increase of copper concentration in sediment leads to progressive increase in the frequency and severity of deformities of the mentum in C. plumosus larvae. Thus, shortening of median teeth in 2.0 +/- 0.2% individuals was the only deformity recorded in control tanks (at 15 mu gg-1 Cu), at 30 mu gg-1 Cu its frequency increased to 16 +/- 2%, and shortening of median-lateral teeth appeared at the same frequency, while at 60 mu gg-1 Cu frequency of both deformities increased to 24 +/- 2% and 28 +/- 4%, respectively, in addition to the appearance of tooth loss in 16 +/- 3% of individuals.

AB  - A prototype of a solid fuel thermo-accumulating furnace has been developed. In order to achieve a higher combustion efficiency, a Pt/Al2O3 catalyst in the form of 3 ± 0.3 mm spheres was applied, which enabled further combustion of flue gases within the furnace. Experimental investigation of the influence of the catalyst on the conversion of CO has been done for different operation regimes and positions of the catalyst. Paper presents selected results regarding CO emission during wood and coal combustion. Investigations suggest a considerable effect of the catalyst and a strong influence of the catalyst position to CO emission reduction. The microstructure of the catalyst beads, characterized by selective chemisorption of CO, has shown the decrease of the number of Pt sites as a consequence of blockage by coke deposits formed during the combustion of solid fuel. .

Uticaj katalizatora na konverziju CO je eksperimentalno ispitan pri različitim operacionim režimima peći i pozicijama katalizatora. Prikazani su rezultati promene emisije CO u toku sagorevanja drveta i uglja. Istraživanja su pokazala značajan efekat katalizatora na smanjenje emisije CO, kao i značaj položaja katalizatora. Mikrostruktura katalizatora, ispitana selektivnom hemisorpcijom CO, je pokazala da u toku sagorevanja čvrstih goriva u peći dolazi do deponovanja ugljenika na katalizatoru što dovodi do blokiranja i smanjenja broja Pt aktivnih centara. .

AB  - Many households in Serbia, using electric thermo-accumulation furnaces for heating, have been forced to find an alternative solution, due to a significant increase in electricity prices during the last decade. A possible solution is replacing electric heating appliances with the solid fuel-fired ones. A prototype of a new concept of thermo-accumulation solid fuel-fired furnace has been developed to meet these growing needs, providing electricity saving together with considerable environmental benefits. Two strategies for reduction of carbon monoxide emission are examined in the paper: application of Pt/Al2O3 catalyst, in the form of 3 ± 0.3 mm spheres, providing further combustion of flue gases within the furnace, as well as an additional emission reduction by means of the air excess control. Experimental investigations of the catalyst influence on the conversion of carbon monoxide have been done for different operation regimes and positions of the catalyst. The paper presents selected results regarding carbon monoxide emission during wood and coal combustion. Investigations suggest a considerable effect of the catalyst and a strong influence of the catalyst position within the furnace to carbon monoxide emission reduction. In addition, experimental tests have been conducted to asses the effect of the air excess control in the furnace on carbon monoxide emission. The amount of combustion air, the flue gas flow rate, and the fuel feeding regime have been adjusted in order to keep the flue gas oxygen content in a relatively narrow range, thus obtaining controlled combustion conditions and lower carbon monoxide emission. In this way, the furnace has been made able to respond to the changes in heating needs, fuel quality and other parameters, which is advantageous in comparison with similar solid-fuel fired furnaces.
