The condition of the super heater has a significant influence on boiler operation and efficiency. Slagging and fouling reduce the heat exchanger efficiency, disturb the local heat balance and require expensive on-load cleaning. Worse, slagging and fouling may prove irreversible if corrective action is not initiated in a timely manner. Excessive cleaning, however, leads to tube ruptures – cause of many forced outages.

EUvis insitu is a one-of-a-kind fully insertable camera system that traverses the boiler under full load operation. With its rotational head it can monitor boiler areas that would otherwise remain inaccessible. EUvis insitu helps you to keep close track of the boiler condition, identify problem areas and damages early in advance and establish a condition-dependent cleaning strategy. Powerful tools help you to analyse, evaluate and archive the information and make it available at your fingertips.

Product Information

Camera head mounted to a traversing lance (6 m length), fully rotational along two axes, Variozoom with optimized filters, digital data transfer, software with graphical user interface for intuitive operation, system control with safety functions, manual and automatic system operation mode, client-server architecture with remote access capability, extensive diagnostic and archiving functions for localizing and quantifying deposits & erosion.

The system requires only water and compressed air for cooling. Installation is turn-key with interface to plant DCS system.
