由于煤炭价格低廉，供应充足，在世界一些地区，煤炭仍然是住宅供暖的主要能源。但是，关于小型器具，特别是手动炉灶燃烧煤炭排放的资料很少。本研究调查了在典型的中欧木炉中燃烧的褐煤块（BCBs）排放的气体和挥发性有机化合物（VOCs），并将其与云杉原木的排放进行了比较。特别强调的是连续批次的排放演变。与木材相比，由芦田褐煤制成的bcb显示出归因于木质素分解的化合物排放量更高，而归因于源自热解的排放量在两种燃料之间没有显着差异。此外，从BCB燃烧中获得的so2排放因子高出20倍，这是众所周知的有害影响。除了减少碳足迹之外，由于二氧化硫排放量的巨大差异，用原木代替bbc作为住宅供暖的燃料可能有益于人类健康，而由于有机排放量的差异相当小，减少有机排放量的潜在影响值得怀疑。
Coal continues to be a major source of energy for residential heating in some parts of the world due to its low price and good availability. However, only little information on emissions for coal combustion in small-scale appliances, in particular manually-operated stoves, is available. This study investigates the emissions of gases and volatile organic compounds (VOCs) from brown coal briquettes (BCBs) burned in a typical Central European wood stove and compares them to emissions from spruce wood logs. Special emphasis was placed on the evolution of emissions over consecutive batches. In comparison to wood, BCBs made from Lusatian lignite showed higher emissions of compounds that were attributed to the decomposition of lignin, while emissions that were attributed to having originated from pyrosynthesis did not show significant differences between both fuels. Furthermore, a 20-fold higher emission factor for SO2was obtained from BCB combustion, which is known for its deleterious effect. In addition to a reduction in the carbon footprint, replacing BCBs with logwood as a fuel for residential heating might be beneficial for human health due to vast differences in SO2emissions, whereas a potential effect from the reduction of organic emissions is questionable due to the rather small differences in organic emissions.
