The poultry waste produced by industrial slaughterhouses typically contains not only feathers, but also a mixture of animal entrails, nails, blood, beaks and whole carcasses. Economical utilisation of this mixture, varying strongly in composition and moisture content, is, in general, difficult. We demonstrate that this awkward material can be successfully used for gasification in a simple, fixed-bed gasifier. The method of gasification, which we developed, enables control of the gasification process and ensures its stability in the operational regime of a working poultry processing plant. The installation, which has been working in Poland for 2 years, utilises 2 tons of feathers per hour and produces syngas of stable composition and fairly high quality. The syngas is burnt in the combustion chamber adjacent to the gasifier. Heat is recuperated in a boiler producing 3.5 tons per hour of technological steam continuously used for the operation of the slaughterhouse. The whole process complies with the stringent emission standards. In the paper we present the end-use device for feather utilisation and describe the underlying gasification and syngas combustion processes. Key elements of the whole installation are briefly discussed. The environmental impacts of the installation are summarized.
工业屠宰场产生的家禽废物通常不仅含有羽毛，还含有动物内脏、指甲、血液、喙和整个尸体的混合物。这种成分和水分含量变化很大的混合物的经济利用通常是困难的。我们证明，这种棘手的材料可以在简单的固定床气化炉中成功地用于气化。我们开发的气化方法能够控制气化过程，并确保其在工作家禽加工厂的运行模式下稳定。该装置在波兰已经运行了 2 年，每小时可利用 2 吨羽毛，生产成分稳定、质量相当高的合成气。合成气在紧邻气化炉的燃烧室中燃烧。热量在锅炉中回收，每小时产生 3.5 吨工艺蒸汽，连续用于屠宰场的运行。整个过程符合严格的排放标准。本文介绍了羽毛利用的最终用途装置，并描述了基础的气化和合成气燃烧过程。简要讨论了整个装置的关键要素。总结了装置的环境影响。
