转杯式燃烧器的配风

转杯式燃烧器是管道加热炉上应用最多的燃烧设备，它具有许多优点，但由于配风不合理，使其燃烧性能不尽人意。根据转杯式燃烧器本身特点，在配风设计上，有三个主要问题应予以重视和解决。一是对入口空气进行分配和整流，使整流后进入炉膛的空气均匀分布，燃烧火焰形成规则并燃烧稳定；二是提高喉口风速，喉口风速提高以后，可使燃烧后期尾部的扩散和混合加强，提高油的燃烧程度；三是燃烧器砖的张角要合适。遵照以上原则，通过加热

Air Feeding of Rotary-Cup Type Burners

Burner of rotary cup type is a burning instrument in most popular use in the heaters for pipleine. In spite of its numerious advantages, this type of burner has a poor performance due to its improper air feeding system. Considering its characteristics, the following three solutions are given to air feeding problems : (1)to distribute and commutate the incoming air so as to achieve uniform air feeding, regular flames and stable burning; (2)to speed up the air feeding at throat in order to improve the burning efficiency; (3)to choose a proper subtended angle for the burner. Based on the foregoing principles, modifications are made for the air feeding system of the Heater 105, and better performances achieved.
