“…PM 2.5 EFs were determined to be in the range of 5.24–26.8 g/kg for bituminous coal and 0.152–5.05 g/kg for anthracite, and the EF values for biomass burning ranged from 4.08 to 26.7 g/kg for crop residues and 1.59 to 16.3 g/kg for wood, , wherein significant discrepancies were observed between the laboratory and field performance. Highly controlled laboratory testing protocols could repeat different operating conditions and easily identify technological parameters that influence cookstove performance, but direct field measurements are still preferable for accurate emission inventory development because they are more realistic and can cover emissions from stoves that are operated under random conditions. ,, …”

“…Meeting all these requirements for cooking by households with limited income would not be easy. The problems associated with start-up materials and reloading of pellets may be mitigated by installing an automatic ignition system and an automated pellet feeder, as measurements in China demonstrate (Clark et al 2017;Deng et al 2018), but doing so adds to the technical complexity and cost. The findings by Deng et al (2018) that emissions increased with increasing amount of pellets fed to the stove during reloading would point to a need for an automated pellet feeding mechanism that supplies pellets continually in small quantities.…”

“…The impact on emissions of reloading of pelletized biomass was measured in a study in China where the stove had mechanisms for rotating the re-loading crank to manually load and reload pellets and an electric coil heater inside the combustion chamber for ignition (Deng et al 2018). PM2.5 emissions in laboratory measurements were more than 70 percent lower than those in the field in the absence of reloading, and CO emissions were 60 percent lower.…”

“…Pollutant emissions are affected by many other factors during combustion. For instance, airflow rates [46], oxidizing and reducing conditions [47], fuel characteristics [48], and user behaviors [21] vary among different residential stoves. Testing automated stoves in the laboratory and the field can be regarded as a combustion process with unified fuel loading and air supply conditions.…”

“…Meanwhile, half-ellipsoidal and cylindrical briquettes have also been shown to have higher thermal efficiency than spherical briquettes [20]. Pelletized biomass fuels and clean automatic stoves have been widely promoted in China because of the observed significant emissions reduction [19,21], but many areas lack biomass resources, and problems of severe slagging and low heating value for agricultural waste combustion are inevitable. Owing to the abundant sources and thermal properties of bituminous coal, we designed a novel bituminous coal pellet (BCP) as an alternative fuel source for households and assessed its emission reduction potential in this study.…”
