Abstract
A soot blower for cleaning heating surfaces of a heat exchanger wherein a lance has jets at its front and is connected at its rear through a soot blower valve to a feed line for a blowing medium. The lance passes through a wall of the heat exchanger and is sealed by a wall casing where the lance passes into the heat exchanger. A connector is provided for a purging medium for the lance between the soot blower valve and the jets of the lance. There is also a connector for a sealing medium on the wall casing. A compressor generates and distributes purging medium and sealing medium for the soot blower connected to the respective connectors. A check valve between the soot blower valve and the purging medium connector prevents flow of blowing medium into the generating and distributing compressor.
