Abstract
THE PURPOSE. Consider a renewable energy source. Compare the proposed design with other pyrolysis technologies and make sure that the proposed design will reduce fuel consumption. METHODS. This article proposes the design and technological principle of the process of pyrogenetic wood processing with the production of various compositions of pyrolysis gas and charcoal. RESULTS. The article describes the proposed design, calculates the heat balance for it, and determines the operational parameters of the technological process. CONCLUSION. The main positive difference between the proposed plant design and technology from other pyrolysis technologies is a high level of fuel economy due to heat utilization at intermediate stages of the process. The heat of the cooled charcoa l and the waste products of complete fuel combustion are utilized. The developed design allows reducing fuel consumption, as well as the range of gaseous components obtained as a result of pyrogenetic decomposition of raw wood in a direct -flow pyrolysis plant can be increased.
