本文包括在选择和设计燃烧器时,确定一二次风的流通截面积,燃烧器开口计算所必须的概念,以及主燃烧器和乏气燃烧器在炉墙上的布置和燃烧室断面和容积计算的推荐。燃烧器的计算和确定燃烧室的主要特性q_V、q_F、q_L 密切联系起来是推荐的特点。因此,工作的最终结果不仅是燃烧器结构、数量和布置的选择,而且还由燃烧条件,燃烧器的功率和燃烧器的布置确定了炉膛尺寸。这样考虑问题比迄今为止还只是根据一个参数q_V 来求得炉膛尺寸要更精确。旋流器及其阻力计算将附带给出。
This paper includes the concepts of determining the cross-sectional area of the primary and secondary air flow, the necessary openings in the burner opening, and the arrangement of the main and exhaust gas burners on the furnace wall and the section and volume of the combustion chamber during the selection and design of the burner Calculated recommendations. The calculation of the burner and the determination of the main characteristics of the combustion chamber q_V, q_F, q_L are closely linked to the recommended characteristics. Therefore, the end result of the work is not only the choice of combustor structure, quantity and arrangement, but also the hearth size determined by the combustion conditions, the burner power and the burner arrangement. It is more accurate to consider the problem so far than to find the hearth size based on a parameter q_V. Cyclones and their resistance calculations are provided.
