摘　　要：作者在研究与设计工作经验积累的基础上，提出烟囱外壁与内衬间设流通空气隔层的设计计算方法它可以降低烟囱外壁内外温差，从而避免或减少烟囱外壁裂缝，节约材料，提高结构耐久性．经过数十年工程实践和不断改进设计的过程，证明它是经济、合理、安全、可靠。Based on the background of experience in research and design, the author puts forward the designing and calculating method for the circulated air strata between the liner and outer wall of chimney. Because the difference in temperature both sides of the outer wall of chimney could be decreased from that, the cracks of outer wall can be avoided or reduced, the structural durability would be increased and the capital cost should be less.Through the engineering practice and ceaseless improving designing for several ten years,this designing method had been proved that it was economical, reasonable and reliable,besides having original idea in the world.
