Carbonization is the process in which wood is heated in a closed environment with a controlled amount of air, producing charcoal as a solid product and secreting water vapor, organic liquids, and noncondensable gases. The burning of these gases generates energy that can be used for the drying wood to be carbonized or for generation of electric power in the carbonization plant itself. The present study had the purpose to conduct an energetic survey of the fractions from charcoal production process, aiming to subsidize and to encourage the technological development of equipment for energetic use of carbonization gases. The results showed that the energy contained in noncondensed gases and in pyroligneous liquid corresponds to a total of 31% of the wood energy used. Two scenarios of synchronizing four kilns were studied in pyrolysis, and a maximum and constant potential of 9.7 MW was obtained in scenario 2. The gas burner was efficient in the emission control, because it reduced CO and CH₄ in the ranges of 97–99% and 68–91%, respectively. Thus, the gas burner is a promising technology for reduction of greenhouse gases and generation of thermal energy from carbonization coproducts.

木材热解副产物用于干燥和发电的能量评估

碳化是在封闭的环境中用受控数量的空气加热木材，以固体产品形式生产木炭并分泌水蒸气，有机液体和不凝性气体的过程。这些气体的燃烧产生的能量可用于干燥要碳化的木材，或用于在碳化设备本身中发电。本研究旨在对木炭生产过程中的馏分进行高能调查，旨在补贴和鼓励高能利用碳化气的设备的技术开发。结果表明，非冷凝气体和热解液体中所含的能量总计占所用木材能量的31％。在热解中研究了两种同步四个窑炉的方案，_4分别在97–99％和68–91％的范围内。因此，燃气燃烧器是减少温室气体和从碳化副产物中产生热能的有前途的技术。
