一、前言利用燃料燃烧获得热量的加热炉,以往的节能技术,一般是加强燃烧管理,实现低空燃比燃烧;提高炉壁的隔热性能,减少散热损失;延长预热段或用换热器等实现回收排放烟气的余热。但是这些技术都是从减少热损失出发,可以说是比较被动的节能技术。使用这些技术的节能效果,必定有一个限度。因而,今后为了更进一步推进节能,必须认识到,加强对炉内强化传热技术的研究是最重要的。在燃烧炉的炉内传热,基本取决于燃烧气体的热辐射能力。为了提高这个能力,与 First, the introduction of the use of fuel combustion furnace heat, the previous energy-saving technologies, the general is to strengthen combustion management, to achieve low air-fuel ratio combustion; to improve the thermal insulation properties of the furnace wall to reduce heat loss; extended preheating section or heat exchanger Waste heat recovery and emission of flue gas. However, these technologies are starting from the reduction of heat loss, can be said to be more passive energy-saving technologies. The energy-saving effect of using these technologies must have a limit. Therefore, in the future in order to further promote energy conservation, we must recognize that strengthening the furnace heat transfer enhancement technology is the most important. Heat transfer in the furnace furnace, basically depends on the thermal radiation of combustion gases. In order to improve this ability, and
