一、前言 研究燃料的燃烧理论是控制炉子热工作过程很重要的一个内容。 油掺水乳化燃料能否用于生产和节油的关键在于它的燃烧机理是否合理。 由于工业炉中气流运动相当复杂以及多种物理和化学变化交替进行,导致气流内热量、质量、动量分布很不一致,所以,冷态试验和局部高温试验(如燃料的单个液滴和燃料流的实验室燃烧试验)等只能部分地模拟工业性燃烧特征。想用这种方法描述炉内真实燃烧状态尚有较大距离。 目前,我们只能通过某些手段(如测定炉膛温度场分布,炉气浓度场分布等)来了解炉子的热工特性。本试验对以乳化油为燃料的反 I. Preface The study of fuel combustion theory is an important part of controlling the thermal operation of a furnace. The key to whether oil-in-water emulsified fuel can be used for production and fuel-saving lies in whether its combustion mechanism is reasonable. Because of the complexity of the gas flow in industrial furnaces and the alternation of various physical and chemical changes, the distribution of heat, mass and momentum in the gas stream is very inconsistent. Therefore, cold tests and localized high temperature tests (such as single drop of fuel and flow of fuel Laboratory combustion test) can only partially simulate industrial combustion characteristics. Want to use this method to describe the true state of the furnace there is a greater distance. At present, we can only know the thermal characteristics of the furnace by some means (such as determining the distribution of furnace temperature field, distribution of furnace gas concentration field, etc.). The test on the emulsified oil as fuel anti
