Camera inspection of exhaust gas lines
Other topics from this section:It is advisable to check flue gas lines/chimney stacks at regular intervals. A visual inspection is a particularly suitable method to determine if the flue gas pipe needs to be cleaned, if the cleaning was successful or if there are any defects in need of repair. Visual inspections are also helpful when renovating or installing a flue gas system, for instance, to visibly inspect crimped seals in flue gas systems.
It is possible to carry out these inspections with a camera. There are a variety of camera inspection systems available to fit different cross-sections and types of flue gas lines. To simplify the visual inspection as much as possible, the inspection camera should offer the following features:
- A pan & tilt color camera head, to inspect the inside and junctions of the flue gas line to the highest standard
- A video memory function for documentation purposes and improved further processing
- A digital distance counter or a locating function via locator to pinpoint the exact location of defects
Saving videos to an SD card also allows the customer who is absent during the inspection to view the inside of their flue gas line at a later point in time.
Performing camera inspections of flue gas lines
Inspections of flue gas lines of condensing boilers often start at the boiler. In other words, the flue gas line is inspected from the bottom upwards. To do so, the inspection camera must be pushed upwards in the flue gas line. The best approach is to use a glass-fiber push rod. That makes it possible to inspect each individual seal and cleaning hatch or similar with the pan & tilt color camera head. Thanks to the locator, it is possible to pinpoint where the camera head is currently located while inspecting the flue gas line. That in turn makes it possible to quickly and simply carry out a damage analysis.
It is possible to professionally comment recorded videos in real time during an inspection, for example to document defects, and then pass the video on to the customer.
Summary:
- Camera inspections facilitate quick and easy checks for damage and inspections of flue gas systems
- Suitable for a wide spectrum of tasks: From flue gas lines through to large chimney stack cross-sections
- Documenting images and voice recordings on a memory card simplify further processing options
