The thermal environment and air quality conditions provided with combined system of chilled ceiling and personalized ventilation (PV) were studied in a simulated office room for two occupants. The proposed system was compared with total volume HVAC solutions used today, namely mixing ventilation and chilled ceiling combined with mixing ventilation. The objective of the study was to evaluate whether...
The effect of the calcium present in lignite on the effectiveness of NO reduction in the reburning method has been studied in the 900–1100°C temperature range. Lignites from three Polish mines were used. The experiments were carried out in a laboratory scale drop-tube furnace reactor. The demineralised lignites were loaded with Ca using: calcium acetate Ca(CH 3 COO) 2 , calcium hydroxide...
The effect of addition of the iron graphite intercalation compound (GIC-FeCl 3 ) to coal tar pitch, used as a carbon precursor, on the porosity development in the resulting steam activated chars, was studied. Different conditions of chars preparation have been considered. Benzene (298 K), nitrogen (77 K), carbon dioxide (298 K) and water (298 K) sorption measurements were taken as basis...
The effect of a Lewis acid addition to a coking coal on the porosity and reactivity towards steam of the resulting iron enriched coal chars are studied. GIC (FeCl 3 graphite intercalation compound) or free FeCl 3 are used as iron containing additives. Coal iron enrichment was performed using either directly FeCl 3 in vapour phase, or by mixing of coal and additives in decaline...
