本文研究采用接近化学计算的空气量进行燃烧时,对发电厂锅炉喷燃器各部件的合理组合有影响的诸因素。现代水管锅炉的燃烧系统主要包括一组布置在一个大的、通常由水或蒸汽管构成的矩形角柱体周围的喷燃器。此室容纳火焰并被正确地称为燃烧室,因为为喷燃器所制约的油/空气混合物在此室中燃烧。从燃烧观点来看,喷燃器/燃烧室的组合是否成功,可从排出烟气的某些特点,特别是从未燃物来加以判断,因为它是随着油/空气之比接近化学计算值而增大的。在研究这些特点与喷燃器设计相互关系之前,拟先讨论喷燃器的设计问题。
This paper studies the factors that affect the sound combination of the various components of a boiler burner in a power plant when burning near the stoichiometric amount of air. The combustion system of a modern water-tube boiler consists essentially of a set of burners arranged around a large, rectangular prism that is usually composed of water or steam pipes. The chamber holds the flame and is correctly called the combustion chamber because the oil / air mixture that is restricted by the burner burns in this chamber. From a combustion point of view, the success of the burner / combustor combination is judged by certain characteristics of the exhaust flue gas, particularly unburned, as it is as the oil / air ratio approaches stoichiometry Value increases. Before examining the interrelationship of these characteristics with the design of the burner, it is intended that the design of the burner be discussed first.
