Abstract
A method for cleaning a precipitator having a hopper defining an interior space and a drain valve is provided. The method includes inserting an explosive device into the interior space defined within the hopper via the drain valve, while the precipitator remains on-line. The method also includes detonating the explosive device to cause particulate matter contained therein to loosen for removal through the drain valve.
Claims18
A method for cleaning a precipitator having a hopper defining an interior space and a drain valve, said method comprising:
- inserting an explosive device into the interior space defined within the hopper via the drain valve, while the precipitator remains on-line;
- detonating the explosive device to cause particulate matter contained therein to loosen for removal through the drain valve;
- and
- monitoring a characteristic of a gas discharged from the precipitator in real-time when detonating the explosive device.
A method for cleaning a precipitator having a hopper defining an interior space and a drain valve, said method comprising:
- providing an apparatus including a pole and an explosive device coupled to the pole;
- inserting the pole through the drain valve of the hopper to place the explosive device in the interior space;
- detonating the explosive device while the pole is inserted through the drain valve and the explosive device is disposed within the interior space;
- and
- monitoring a characteristic of a gas discharged from the precipitator in real-time when detonating the explosive device.
A method for cleaning a precipitator including a particle extraction assembly with a plurality cells each including an energized extraction device that extracts particulate matter from exhaust gases of a fuel-burning apparatus, said method comprising:
- selecting one of the cells for cleaning;
- and
- detonating an explosive device in the selected cell while the extraction device of the selected cell is de-energized, and while the extraction device of at least one remaining cell is energized, to facilitate cleaning the selected cell while the precipitator remains on-line.
