烧结烟囱高度设计计算

摘要

结合180 m2烧结工程介绍了烧结主抽系统中烟囱高度设计计算的一些理论及公式。通过计算可知,烟囱抽力和环保要求是影响烟囱高度的因素,主要受制于环保要求。抽力要求限定的烟囱高度≥40 m,SO2着地浓度限定的烟囱高度≥63 m,氮氧化物着地浓度限定的烟囱高度≥81 m。%Combining withtheories and formulas ofdesign calculation of chimneyheightfor main exhausting system of 180 m2 sintering project,from calculation it can be concluded thatchimney draught and environmental protection requirements are main factors that influence chimney height,among which environmental protectionrequirement is the key factor.Chimney draught asks the limited height is no less than 40 m;SO2 ground pollutant concentration asks the limited chimney height is no less than 63 m.Nitrogen oxidesground pollutant concentration asks the limited chimney height is no less than 81 m.
