Method for improving D-shaped-inner-tube chimney
The invention relates to a method for improving a D-shaped-inner-tube chimney, and belongs to the technical field of chimney design and construction. According to the method, the utilization efficiency coefficient of an outer tube chimney is increased, meanwhile, the increase of the diameter of inner tubes is controlled, and the balance point of the needed technology and economy is found by adjusting the cutting half angle theta. According to the method, the defect that the application of a D-shaped jacketed chimney technology is limited due to insufficient economic cost under the condition that the unit prices of inner and outer tube materials are greatly different is overcome. According to the technical scheme provided by the invention, by actively sacrificing part of the advantages of an outer tube of an original D-shaped jacketed chimney, the increment of the inner tube material is reduced to a relatively low level, so that the overall economic and technical level of the chimney isimproved, and the application range of the original D-shaped jacketed chimney is expanded.
本发明涉及一种改进“D”形内筒烟囱的方法，属于烟囱设计与施工技术领域。本发明在提高外筒烟囱“利用效率”系数的同时，控制内筒直径的增幅，通过调整切割半角θ的大小，找到所需技术与经济的平衡点。本发明克服了“D”形套筒烟囱技术在内外筒材料单价相差悬殊的情况下，由于经济成本上的不足，而限制了应用。本发明提供的技术方案通过主动牺牲原“D”形套筒烟囱外筒的部分优势，将内筒材料增量降到较低水平，以提高烟囱整体经济与技术水平，从而扩大原“D”形套筒烟囱的应用范围。
