中心回燃式燃油锅炉燃烧室实验研究

中心回燃式锅炉自引进以来一直没有一种理想的燃烧室传热计算方法，本文根据中心回燃式锅炉燃烧室内射流火焰与回流烟气之间存在着强烈的掺混，认为燃烧室传热计算中不应忽略对流换热。提出了适合中心回燃式锅炉燃烧室传热的计算方法，并通过实验加以验证。

Experiments of Oil - fired Boiler Chamber with Central Reverse Flame

An ideal heat transfer calculation method has not been found since central reverse flame oil (gas)-fired boiler was introduced.There is a strong adulteration between the jet and the circumfluence occurs in combustion.Thus both radiation and convection need to be considered for the heat transfer flux calculation in the chamber.According to the above theory,a new heat transfer calculation method suitable for central reverse flame oil(gas)-fired boiler was brought forward and verified by experiments.
