自1981年起开展了将农林残余物转换为低热值煤气的研究工作,研制了ND-400等几种气化装置,本文介绍了设计特点、能量覆盖范围、燃料的分类方法以及针对不同燃料而采用的各种对策。 文章最后部分介绍了ND-400气化炉的应用实例,该装置在中国南方茶叶生产方面取得了一定进展。该项能源开发应用技术在全国都有其发展的潜力。 Since 1981, the research work of converting agricultural and forestry residues into low calorific value gas has been carried out. Several types of gasification devices such as ND-400 have been developed. This paper introduces the design features, energy coverage, classification methods of fuel, Various measures adopted. The final part of the article describes the ND-400 gasifier application example, the device in southern China has made some progress in tea production. The energy development and application of technology in the country has its potential for development.
