低热值燃料稳定燃烧的研究现状与进展

随着经济的持续发展,我国的能源需求不断增加.即便煤炭产量以及石油进口量都在不断刷新也难以保障能源的安全供给.因此,节约能源,扩大可利用的能源资源范围,对我国的经济建设极为重要.低热值燃料的应用能提高能源利用效率,但其热值低,稳定燃烧难以控制,需要在组织燃烧场、拓展可燃极限、稳定燃烧方面争取技术突破.本文将低热值燃烧技术分成两类进行了综述,一类是优化着火条件,一类是优化燃烧场结构,并介绍了国内外的一些低热值燃料燃烧实例,探讨了这方面的应用基础研究和技术开发现状.

Research and Development of Stable Combustion Using Low Heat Value Fuel

The energy requirement has been increasing with the continuous development of the economy of our country.It is difficult to assure the energy supplement safely even though the coal production and the petroleum import quantity are continuously refreshed.Therefore,saving energy and extending the available energy resource are essentially important for the economy development.Utilization of the fuel with low heat value is helpful to increase the energy efficiency.However,stable combustion is difficult to fulfill due to the low heat value.Breakthrough in the organization of the combustion flow field,extension of the flammable limit and combustion stabilization are necessary.Including introduction of technology applied in China and other countries,review is given from the following two points of view in this paper: optimizing the fuel ignition condition and combustion field structure,which can provide the guideline for the fuel combustion with low heat value.
