“…Lower variations and fluctuations existed throughout the overall combustion compared with those observed for traditional fuels in our earlier studies [26,27]. These results are consistent with previous research on pellet stoves [28,29]. The contributing factor for this phenomenon is the combustion of BCPs occurring through a continuous loading process and air supply, showing a weaker distinction between devolatilization and flaming phases.…”

Coal is China’s dominant energy source, among which bituminous coal is the most extensive and plentiful. Using bituminous coal resources to design a low-emission household fuel is very important for rural poverty areas. In this work, a new type of bituminous coal pellet (BCP) fuel using an automatic prototype pellet stove was designed for the first time. This study mainly shows the emission characteristic results of BCPs and some comparisons with other commercial solid fuels. Fuel property, PM2.5 morphology, and ash characteristics of the novel fuel were also assessed. In terms of fuel properties, BCPs had a cold compressive strength of 637.2 N, a heating value of 22.26 MJ/kg, and many fine pores in the cross-section for air entry. The real-time emissions of BCPs were stable during combustion. The emission factors of PM2.5 and CO of BCPs were 1.36–2.29 g/kg and 11.1–18.0 g/kg, which were significantly lower than those of bituminous chunk and bituminous briquette (p < 0.05). PM2.5 and CO reduced emissions by 83–90% and 61–76%, respectively, compared with raw coal chunk. According to the chemical composition and morphological characteristics, the PM2.5 from BCP combustion can be divided into fine particulates, molten char particles, and char fragmentation. The ash from BCPs had a higher melting temperature (over 1300 °C), with removable ash agglomeration. Overall, the results presented in this study highlight that turning bituminous coal into pellets and burning them in automatic stoves could noticeably reduce PM2.5 and CO emissions, effectively improving rural air quality.

“…Table 1 shows the characteristics of the waste wood used in this study compared with the results of other studies. Our results indicated that the components of the waste wood matched the carbon and hydrogen constituents of spruce pellets and beech wood (Poláčik et al, 2021), certified and uncertified pellets (Vicente et al, 2020), and agricultural residues (Vamvuka et al, 2020). However, a higher moisture content was found in the waste wood as a result of their sources and the fact that it was stored in the open before being used as feedstock in boilers.…”

“…Biomass combustion has been shown to be an important source of air pollution in northern China (Xu et al, 2017;Xu et al, 2020;Xu et al, 2021) and in Europe (European Environment Agency, 2013;European Union, 2015). Many studies have focused on the emissions of NOx and other pollutants (CO, VOCs, PAHs, and metals in PM) (Vamvuka et al, 2020;Poláčik et al, 2021;Zhang et al, 2020;Kong et al, 2021;Jaworek et al, 2021). In order to address the problem of pollution and to reduce emissions, it is important to take into consideration the aspects of combustion efficiency, operating conditions and air pollution control devices (Caposciutti et al, 2020;Oluwoyea et al, 2020).…”

“…The temperature reached by dry wood (9 % moisture) is the highest recorded in the study and, in the same way, is that reach a higher percentage of efficiency with 88,1 % because they give off a higher calorific value and a temperature of 275,1 °C for gases in the stable reload stage of combustion. The atmospheric pollutants produced by fuel batches with higher moisture concentrations have a significant impact on health, particularly in people with a risk of respiratory diseases, according to studies by Kim et al (2011) and Poláčik et al (2021).…”

Pollutant residential emissions from wood stoves have significant impacts both on the environment and people's health. The above makes it essential to know the types of volatile organic compounds emitted during combustion and explore their relationship with particulate matter and greenhouse gas emissions. This paper studies and analyzes these emissions using Eucalyptus globulus as fuel varying its moisture levels. Emissions were determined using an adapted commercial stove. The concentration levels of volatile organic compounds and particulate matter increase with the moisture of wood. When analyzing volatile organic compounds, particulate matter, and O 2 with the combustion stages of wood, it is found that their concentrations were higher in the ignition and the reload stage. The concentrations of CO 2 and NO x were higher in the reload stage. Other chemical compounds, such as toluene, xylene, and benzene, were also found within the volatile organic compounds listing, which increased their concentration in the ignition and stable reload stages. However, in the quenching stage, they are not present. Finally, the dispersion of these molecules in the environment is evaluated, obtaining that if the atmospheric conditions are adverse, these molecules remain in the environment in direct contact with the people living in those places.
