Abstract:

To study the characteristics of different technologies and equipment of straw fuel utilization, and explore the appropriate mode and development path of straw fuel utilization in Northeast China, based on field investigation combined with practical operation experience and cost-effectiveness, this paper analyzes the current situation, process characteristics and development advantages of straw fuel utilization in Northeast China, and sums up three heating modes utilized in the region. The “one village, one factory” household straw briquette utilization mode is suitable for scattered residential rural area. The biomass boiler transformation heating mode is suitable for public institutions in villages and towns with large heating area and the cost can be decreased by 30% in heating period compared with coal-fired boiler. The straw bundled direct fired central heating mode with large and medium-sized boilers could be adapted in cities or towns and its cost is much lower, which can be decreased by 30%-36% in the heating period compared with coal-fired boiler. Finally, the countermeasures of strengthening organizational leadership, innovating development concept, perfecting market mechanism, paying attention to technical support, strengthening publicity and consciousness promotion are put forward based on the key problems existing in the utilization of straw fuel in Northeast China.

Key words: Northeast China, agricultural straw, fuel utilization, biomass briquetting, direct combustion of bundled biomass, clean heating, development and utilization mode
