Abstract
A method for the acceleration of an electromagnetic rapper, particularly for an electrostatic precipitator, which includes a metal cylinder as a hammer, an electrical coil for lifting the metal cylinder and a coil energizer for energizing the electrical coil. For cleaning a surface the metal cylinder is lifted by an initial electrical pulse generated by the coil energizer. The coil energizer supplies the electrical coil with an additional electrical pulse so that the metal cylinder is accelerated when it has reached the maximum point of its trajectory.
