    • A combustion control apparatus comprises a premix combustion burner requiring primary air, an injector disposed in a primary air passage and including a constricted section having a fixed diameter and length, an enlarged section communicating with the constricted section and a fuel injecting port disposed concentrically with the constricted section and in a predetermined region, and a pressure regulator disposed in a fuel feed passage communicating with the fuel injecting port, the arrangement being such that the pressure regulator is controlled so that the pressure difference between the outlet section of the pressure regulator and the inlet section of the injector may be within the fixed range of the pressure difference produced between the inlet and constricted sections of the injector on the basis of the amount of primary air at the time of the lowest input, thereby maintaining the ratio between the amounts of air and fuel at a constant value and securing combustion stability and high combustion efficiency. Particularly, the apparatus is characterized in that it is highly effective even if the fuel pressure and air pressure are low.
    • 一种燃烧控制装置,其特征在于,包括需要一次空气的预混合燃烧器,设置在一次空气通路内的喷射器,具有固定直径和长度的收缩部,与所述收缩部连通的扩大部,以及与所述收缩部同心配置的燃料喷射口, 所述压力调节器设置在与所述燃料喷射口连通的燃料供给通道中,所述压力调节器被调节为使得所述压力调节器的出口部分与所述压力调节器之间的压力差 喷射器的入口部分可以基于在最低输入时的一次空气量的基础上在喷射器的入口部分和收缩部分之间产生的压力差的固定范围内,从而保持喷射器的入口部分之间的比例 空气和燃料具有恒定值并确保燃烧稳定性和h 燃烧效率高。 特别地,该装置的特征在于,即使燃料压力和空气压力低,也是非常有效的。
