1.燃烧器现状目前各国生产的沥青搅拌站燃烧器的火焰调节原理,基本都是通过伺服电动机、机械连杆机构带动风门、油门同步转动来实现的。这种调节方式普遍存在着风油比调节困难、点火成功率低、耗油量高和燃油泵寿命短等问题,严重时甚至发生除尘布袋着火事故。 1. The status of the burner At present, the flame regulating principle of the burner for asphalt mixing plant produced in various countries is basically realized by the servo motor and the mechanical connecting rod mechanism which drive the damper and the accelerator to rotate synchronously. This adjustment method is generally the wind oil than the adjustment difficulties, the ignition success rate is low, high fuel consumption and short life of the fuel pump and other issues, and even serious cases of dust bag fire accidents.
