撞击流技术在发电相关领域的研究与应用进展
|
摘要
节能降耗是中国发电行业当前发展的主要方向。撞击流在撞击的瞬间能够产生极大的相间相对速度,并形成一个相对狭窄的高度湍动区,能够极好地提高热、质传递。撞击流的这种性质可被广泛应用于发电行业的相关领域,尤其是在燃烧、干燥、污水处理、脱硫脱硝、煤气化、除尘等领域具有广阔的应用前景。在简述撞击流技术基本原理的基础上,总结了近年来撞击流技术的研究进展,并就撞击流技术在发电行业相关领域的应用前景进行了讨论,以期为撞击流技术在发电行业的进一步应用提供参考。
The ene rgy sa vi ng an d c on su mpti on reduction is the main development direction of China's power generation industry. The impinging stream can generate a great relative phase-to-phase velocity at the moment of impact, and form a relatively narrow height turbulence zone, which can greatly improve the heat and mass transfer. This nature of flow can be widely used in the related fields of the power generation industry, especially in the areas of combustion, dry ing, sewage treatment, desulfurization and denitrification, coal gasification, dustremoval, etc. In this paper, based on a brief introduction to the basic principle and classification of impinging stream technology, the research progress of impinging stream technology in recent years is summarized, and the application prospects of impinging stream technology in related fields of power generation industry are discussed, in order to provide reference for further application of impact flow technology in the power generation industry.
