这将导致燃烧器出口处热量局部聚集，烟气温度非常高，造成炉内温度分布不均及喷嘴的损坏。

These will result in local heat accumulation at the outlet of burner, very high temperature of flue gas, uneven distribution of temperature in furnace and damage of nozzles.

采用FLUENT软件对大气式燃气燃烧器的引射器进行数值模拟，得出喷嘴位置与一次空气系数的关系。

The numerical simulation of the injector of atmospheric gas burner is carried out using software FLUENT, and the relationship between nozzle position and primary air coefficient is obtained.

所述喷嘴体朝泵体的外部延伸，以便将增压油供至一个燃烧器。

The nozzle body extends towards the outside of the pump body to provide a burner with supercharging oil.
