循环流化床技术课程教学探讨

The Teaching Discussion on the Course of the Technology of Circulating Fluidized Bed

循环流化床燃烧方式是一项新型高效的清洁煤燃烧技术,它具有燃烧效率高、燃料适用范围广等优点。因此,基于这种燃烧方式的循环流化床锅炉在火力发电领域的比重日益增加。很多高校都开设了循环流化床课程,它也逐渐成为热能与动力工程专业的重要专业课之一。然而,由于该课程较为抽象,在教与学的过程中出现了很多问题。针对这些问题,结合教学实践,从优化教学方法、丰富教学手段、引入科研进展和工程案例及注重实践能力培养等方面探讨了新形势下循环流化床技术的课程改革。借此希望有效地激发学生学习兴趣,提高教学效果。

Circulating fluidized bed combustion is a new type of high efficient clean coal combustion technology. It offers several advantages such as higher combustion efficiency, larger fuel applicable range. Therefore, circulating fluidized bed boiler based on this technology is increasing gradually in thermal power generation market. At present, the course of circulating fluidized bed has been set in many universities. And it also gradually becomes one of the important specialized courses of thermal energy and power engineering major. However, there are a lot of problems in the process of teaching and learning, due to its abstract concepts. In this paper, several methods such as optimize teaching method, extend teaching approach, introduce scientific development and engineering project and cultivating practice ability have been introduced and discussed for the curriculum reform of circulating fluidized bed technology. Moreover, this paper could provide some guiding suggestions for improving students＇ learn interest as well as teaching effects.
