| 摘 要： | 根据北京市某燃气锅炉房的实际情况,对烟囱保温状况与排烟性能的关系进行了计算分析,结果表明:减小保温层厚度会使烟囱的排烟性能下降,尤其在保温层厚度较小时,这种影响更大。对于所研究对象,在设计排烟量的情况下,当烟囱保温层厚度小于15mm时,排烟系统的抽力计算值小于阻力计算值。当保温层厚度增加到20mm以后,对改善排烟性能的作用较小。

| Abstract: | Analyses and calculates the relationship between heat-insulation status and smoke exhaust performance of chimney in a gas-fired boiler house in Beijing.The results show that the smoke exhaust performance descends with the thickness reducing of heat-insulation layer,and the influence is more remarkable when the thickness is small.For the designed smoke flow,the draft is less than the resistance force of smoke flow when the heat-insulation thickness is less than 15 mm,and the improvement is small when the thi... |
