An apparatus and method are disclosed for continuously delivering and non-intermittently introducing a liquid into a main flow. An exemplary apparatus includes a supply line, a delivery line, a delivery device for delivering a mass flow of the liquid from the supply line to the delivery line, and at least one atomizing element communicating with the delivery line. A branch line which branches off from the delivery line can be arranged in the delivery direction downstream of the delivery device and upstream of the atomizing element, at least one changeover and/or regulating member for shutting off and/or throttling the branch line being arranged in combination with the branch line.
