民用燃具的运行特性

燃气成分的变化将引起燃气燃烧特性的改变，燃具热负荷、一次空气系数、火焰结构及燃烧稳定性发生变化。分析了当燃气成分发生变化时，配有大气式燃烧器的民用燃具在不加任何调整的情况下，其运行工况的变化规律，这对燃气互换性和燃具适应性的研究以及燃具的设计均有实际意义。

OPERATION CHARACTERISTICS OF DOMESTIC GAS APPLIANCE

The change of gas components must leadto the change of combustion features including heat input, primary air ratio, flamestructure and combustion stability as for gas appliance, which probably make gas applianceout of order.This paper analyzes in detail the operation situations of domestic gasappliance equipped with atmospheric gas burner, under the influence of the change of gascomponents without any adjustment about it.It's meaningful of these rules to direct theresearch in the fields of interchangeability of gas and adaptability of gas appliance,andhow to appropriately design domestic gas appliance in practice.
