摘要:

目的 基于秸秆打捆直燃集中供暖模式发展概况与特点，开展模式案例综合效益评价，为北方地区秸秆处理难题和冬季农户清洁取暖提供新思路。方法 文章采用文献归纳法、政策梳理法、案例分析法等研究方法对秸秆打捆直燃集中供暖模式发展现状进行综述、总结模式特点，进行供暖模式综合效益评价。结果 （1）秸秆打捆直燃集中供暖技术 在丹麦、比利时等国发展成熟，运用广泛，在我国则处于起步阶段，有待进一步运用和推广；（2）该模式具有可当季消纳大量秸秆，工艺简单、易推广，零碳排放、清洁环保等优点；（3）通过对河北省衡水市景县柯良农场秸秆打捆直燃集中供暖项目进行综合评价可知，经济效益上供暖站有利可图、用户采暖费用更低；生态效益上节能减排效果好、村庄环境质量得到改善、促进当地农业绿色发展；社会效益上该模式具有良好的示范作用，一定程度上解决了当地部分就业问题，也促进了农场自身发展。结论 秸秆打捆直燃集中供暖模式作为我国新提出的一项生物质能清洁供暖技术模式，其经济效益、环保效益以及社会效益显著，国家可将其纳入北方地区分布式供暖的主推项目技术，优化和创新供暖模式，加大宣传推广力度。

Abstract:

To summarize the development situation and characteristics of straw bundled direct fired central heating mode, we carried out a comprehensive benefit evaluation of the mode, so as to provide ideas for solving the problems of straw treatment in northern China and clean heating for farmers in winter. Using literature induction method, policy combing method, case analysis method and other research methods to review the development status of the straw-bundled direct-fired central heating mode, this study summarized the mode characteristics, and evaluated the comprehensive benefits of the heating mode. The following results can be obtained as follows. Firstly, the straw-bundled direct-fired central heating technology was mature and widely used in Denmark, Belgium and other countries, but it was in its infancy in my country and needed to be further used and promoted. Secondly, the model had the advantages of being able to consume a large amount of straw in the current season, simple process, easy to promote, zero carbon emission, clean and environmentally friendly, etc. Thirdly, through the comprehensive evaluation of the direct-fired central heating project in Keliang Farm, Jingxian county, Hengshui city, Hebei province, in terms of economic benefits, heating stations were profitable and users had lower heating costs. In terms of ecological benefits, the effect of energy saving and emission reduction was good, the environmental quality of the village had been improved, and the green development of local agriculture had been promoted. In terms of social benefits, this model had a good demonstrative effect. It had solved some local employment problems to a certain extent, and had also promoted the development of the farm itself. As a new biomass energy clean heating technology model proposed by my country, the straw-bundled direct-fired central heating mode has significant economic, environmental and social benefits. The state can incorporate it into the main project technology of distributed heating in the northern region, optimize and innovate heating models, and increase publicity and promotion.
