8 Periodic inspection and cleaning
The electrostatic precipitator system must be inspected and cleaned at appropriate
intervals depending on the operating hours and fuel quality.
Inspection and cleaning must be repeated after not more than 1000 operating hours or
at least every six months. For less efficient fuels (e.g. high ash content) this work
needs to be carried out more frequently.
Thorough cleaning of the entire electrostatic precipitator system and the boiler must
be carried out immediately prior to emissions measurement.
8.1 Cleaning electrodes and the interior
Carry out the following cleaning work on all modules of the electrostatic precipitator
system.
❒ Loosen screws and remove the top cover
❒ Loosen the upper screws and unhook the side panels
❒ Remove maintenance cover
❒ Loosen screws on the insulator and remove the high-voltage cable
IMPORTANT: When fitting the maintenance covers, use the previously removed brass
nuts! If nuts are lost or can no longer be fitted due to wear, replacement nuts must be
ordered from Froling GesmbH (Art. No. T206173).
