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. .
AB  - U prototipu termo-akumulacione peći na čvrsto gorivo, primenjen je Pt/Al2O3 katalizator, u obliku sfera veličine 3 ± 0.3 mm, sa ciljem da poveća efikasnost sagorevanja i naknadno sagori gasove unutar peći. 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.
