“…For comparison purposes, it is worth indicating that carbon monoxide concentration while firing cork residue pellets or vine shoots alone was higher (3100 and 9000 mg/m 3 , respectively). Similar conclusions were drawn for combining tomato residues, olive stones and cardoon with wood pellets (González et al, 2004). The lowest carbon monoxide concentration was obtained for the following mixtures: tomato residues/wood (75/25 wt%) 5159 ppm, tomato residues/ olive stones (50/50 wt%) 2013 ppm, cardoon/wood (50/50 wt%) 437 ppm, olive stones/ wood (25/75 wt%) 4157 ppm.…”

“…Even when applying special furnaces designer for a specific biomass type (González et al, 2004;Verma et al, 2011) it is hard to obtain carbon monoxide concentration as low as in case of wood pellets.…”

Tests for combustion of hay and sunflower husk pellets mixed with wood pellets were performed in a horizontal-feed as well as under-feed (retort) wood pellet furnace installed in boilers with a nominal heat output of 15 and 20 kW, located in a heat station. During the combustion a slagging phenomenon was observed in the furnaces. In order to lower the temperature in the furnace, fuel feeding rate was reduced with unaltered air stream rate. The higher the proportion of wood pellets in the mixture the lower carbon monoxide concentration. The following results of carbon monoxide concentration (in mg/m 3 presented for 10% O 2 content in flue gas) for different furnaces and fuel mixtures (proportion in wt%) were obtained: horizontal-feed furnace supplied with hay/wood: 0/100 -326; 30/70 -157; 50/50 -301; 100/0 -3300; horizontal-feed furnace supplied with sunflower husk/wood: 50/50 -1062; 67/33 -1721; 100/0 -3775; under-feed (retort) furnace supplied with hay/wood: 0/100 -90; 15/85 -157; 30/70 -135; 50/50 -5179; under-feed furnace supplied with sunflower husk/wood: 67/33 -2498; 100/0 -3128. Boiler heat output and heat efficiency was low: 7 to 13 kW and about 55%, respectively, for the boiler with horizontal-feed furnace and 9 to 14 kW and 64%, respectively, for the boiler with under-feed furnace.

“…The emission of CO resulted from a low combustion temperature and insufficient supply of O 2 ; fuel was not well mixed with air and the residence time of the combustion gases was too short (Eskilson et al, 2004;Gonzalez et al, 2004;Ozil et al, 2009;Tissari et al, 2009;Roy and Corscadden, 2012). Studies by Gupta et al (2001), Edward et al (2004 and Koppmann et al (2005) reported that incomplete combustion from forest fires produces a high quantity of CO.…”

While peatland has long been exploited for agricultural activities, these make it vulnerable to fires, which emit pollutants into the atmosphere and adversely affect air quality. The aim of this study was thus to determine the main composition of air pollutants from peat soil combustion. The main parameters of the related gas pollutants, e.g., SO 2 , NO 2 , CO, O 3 and PM 10 , and their components, such as anions, cations, heavy metals and levoglucosan, have been determined. The gas concentration was determined using the colorimetric method after the air had been assimilated into absorbing solutions. The PM 10 concentration was established using a low volume air sampler equipped with weighted filter paper. The anion concentration of PM 10 was analyzed using ion chromatography, while the cation and heavy metal concentrations were ascertained using inductively couple plasma-mass spectroscopy (ICP-MS). Moreover, the concentration of levoglucosan was determined using the Anthrone-Sulfuric Colorimetric method. The results show that the dominant gas from the emission of burning peat soil was CO (13850-20610 μg/

“…Gonzalez et al [1,2] studied the combustion of three types of pellets, one of them from tomato residue in boilers for domestic use. Mangut et al [3] carried out a thermogravimetric study of the thermal decomposition of residues from the tomato processing industry: peels, seeds and peels + seeds.…”
