Abstract
The present disclosure relates to a soot blower including: a lance tube which includes one end that reciprocally moves in one direction on a surface of an inlet port of a flow path of the tubular heat exchanger; a drive unit which is connected to the lance tube and reciprocally moves and rotates the lance tube in the one direction; a first nozzle which is connected to the one end of the lance tube and discharges steam to the inlet port; and a second nozzle which is disposed adjacent to the first nozzle and connected to the one end of the lance tube and discharges solid particles to the inlet port, and the present disclosure relates to a method of cleaning a tubular heat exchanger by using the soot blower.
Claims23
A soot blower which includes a flow path through which a fluid passes and cleans a tubular heat exchanger positioned on the flow path, the soot blower comprising:
- a lance tube which includes one end that reciprocally moves in one direction on a surface of an inlet port of the flow path;
- a drive unit which is connected to the lance tube, reciprocally moves the lance tube in the one direction, and rotates the lance tube clockwise and counterclockwise;
- a first nozzle which is connected to the one end of the lance tube and discharges steam to the inlet port;
- and
- a second nozzle which is disposed adjacent to the first nozzle and connected to the one end of the lance tube and discharges solid particles to the inlet port.
A method of cleaning a tubular heat exchanger in which a fluid performs heat exchange on a flow path, the method comprising:
- discharging steam by a soot blower that reciprocally moves and rotates in one direction on a surface of an inlet port of the flow path;
- and
- discharging solid particles by the soot blower that reciprocally moves and rotates in the one direction on the surface of the inlet port.
