“…There are four different sub-fronts in a smouldering fire: preheating, drying, pyrolysis and oxidation (Rein et al 2009). The preheating front, occurring in a range of temperatures up to 1008C, emits water vapour in large quantities and is not involved in chemical reactions (some volatiles may also be released at this stage but are in trace amounts) (Usup et al 2004;Rein et al 2009;Yang et al 2016). At temperatures above 2008C, pyrolysis dominates.…”

Abstract. Smouldering peat fires, the largest fires on Earth in terms of fuel consumption, are reported in six continents and are responsible for regional haze episodes. Haze is the large-scale accumulation of smoke at low altitudes in the atmosphere. It decreases air quality, disrupts transportation and causes health emergencies. Research on peat emissions and haze is modest at best and many key aspects remain poorly understood. Here, we compile an up-to-date inter-study of peat fire emission factors (EFs) found in the literature both from laboratory and from field studies. Tropical peat fires yield larger EFs for the prominent organic compounds than boreal and temperate peat fires, possibly due to the higher fuel carbon content (56.0 vs 44.2%). In contrast, tropical peat fires present slightly lower EFs for particulate matter with diameter #2.5 mm (PM 2.5 ) for unknown reasons but are probably related to combustion dynamics. An analysis of the modified combustion efficiency, a parameter widely used for determining the combustion regime of wildfires, shows it is partially misunderstood and highly sensitive to unknown field variables. This is the first review of the literature on smouldering peat emissions. Our integration of the existing literature allows the identification of existing gaps in knowledge and is expected to accelerate progress towards mitigation strategies.

“…Subsequent heating above this temperature increases the pyrolysis rate, forming carbonaceous char as a product. In this front, peat emits VOCs, PAHs, trace levels of CO, CO 2 and water vapour (Usup et al 2004;Yang et al 2016). Peat oxidation starts at temperatures of ,3508C and is the main source of CO and CO 2 (Rein et al 2009).…”

“…Thermogravimetry-differential scanning calorimetry coupled with Fourier transform infrared spectroscopy and quadrupole mass spectroscopy (TG/DSC/FTIR/QMS) is an important and often used analysis tool in order to evaluate both thermal stability and the decomposition mechanism of many different structure compounds [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Many researches and engineers applied this analysis method to their studies because it allowed evaluating not only the thermal resistance of the various materials but also the type of the decomposition gaseous products emitted under heating or burning the materials.…”

“…In addition by the analysis of the type of the volatile decomposition products emitted under heating of the materials, it is possible to evaluate the decomposition course and the most probable decomposition mechanism of organic, inorganic and polymeric materials. Such knowledge is basic in many practical applications where the materials are subjected to high temperatures [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Most of the materials which have practical applications are manufactured, utilized and converted under the access of oxygen.…”

The oxidative thermal stability along with the identification of the volatile decomposition products under heating of terpene acrylate homopolymers by using TG/ DSC/FTIR/QMS-coupled method was presented. It was found that the decomposition of poly(geranyl acrylate) and poly(neryl acrylate) had quite different course as compared to the decomposition process of poly(citronellyl acrylate) under oxidative conditions. FTIR and QMS analyses confirmed mainly the formation of terpene hydrocarbons, propane, propene, acetic acid, CO, CO 2 and H 2 O as the volatile decomposition products under heating of the hompolymers. The results obtained indicated the complex decomposition process of terpene acrylate homopolymers including the random ester bond scissors, the random main carbon chain scissors, decarboxylation, dehydration and oxidation processes of formed gaseous decomposition products and a residue which led to the full decomposition of homopolymers at ca. 600°C under oxidative conditions.
