在通常大气鼓风(干风)和鼓风中含有少量水蒸汽(水风)的条件下进行了燃料层燃烧与气化动力学特性的工业性试验研究。试验是在与工业性层燃炉基本相同的层燃炉试验台上进行的。文中对试验目的、试验装置和试验研究方法作了扼要的说明;介绍了试验结果,并作了初步的分析。介绍了关于燃料层燃烧与气化动力学特性的理论,此理论在水风的条件下是不够完整的。因而,作者参照的理论,提出了描述水风条件下燃料层燃烧与气化过程的计算方案,并将计算结果与试验结果作了比较。试验和计算结果表明在燃料层燃烧与气化动力学方面,水风比干风较为有利,但不显著;物理方面有待进一步研究。
Industrial experiments on combustion and gasification kinetics of the fuel layer were carried out under the conditions of normal atmospheric blast (dry wind) and small amount of water vapor (wind) in blast air. The test was carried out on a stratum furnace test stand essentially identical to an industrial stoker burner. In this paper, the purpose of the test, test equipment and experimental research methods are briefly described; test results are introduced, and made a preliminary analysis. The theory about the combustion and gasification kinetics of fuel layer is introduced. The theory is not complete enough under the condition of water wind. Therefore, the author refers to the theory, proposes a calculation scheme for describing the combustion and gasification process of the fuel layer under the condition of water and wind, and compares the calculated result with the test result. The experiment and calculation results show that the water wind is more favorable than the dry wind in the combustion and gasification kinetics of the fuel layer, but not significant; the physical aspects need further study.
