Abstract
A soot blower unit with an axially moved soot blower for the cleaning of heating surfaces of a heat exchanger (1) consists of a lance tube (4) and of a travel carrier (11), which is provided with a track rail (9) and fastened at the wall (2) of the heat exchanger (1). The lance tube (4) is guided at its forward end in a lance tube guide (15) and connected at its rearward end with a blower carriage (7), which is movable on the track rail (9). The vertical spacing of the track rail (9) of the travel carrier (11) from the forward end (h.sub.1) of the lance tube (4) is less than from the rearward end (h.sub.2), which is retained by the blower carriage (7), of the lance tube (4).

- said travel carrier being secured to a wall of said heat exchanger;
- a blower carriage connected to a rear end of said lance tube and being movable on said track rail;
- said lance tube being driven from a rest position by said blower carriage axially into said heat exchanger;
- a lance tube guide, said lance tube having a front end guided into said lance tube guide;
- an end plate, said lance tube guide being secured to said wall of said heat exchanger through said end plate said lance tube guide being adjustably spaced from the travel carrier;
- said track rail of said travel carrier being vertically spaced by a first spacing from a front end of said lance tube in said rest position of said lance tube, said track rail of said travel carrier being vertically spaced by a second spacing from a rear end of said lance tube held by said blower carriage, said first spacing being less than said second spacing for forming an angle between said lance tube and said track rail.
