KOB PYROT - Metal mesh filter

Metal mesh filter
The metal mesh filter removes dust and fine dust from the flue gas. It
is characterised by a particularly high degree of separation. This
ensures a fine dust content of less than 20 mg/Nm³ in the clean gas.
The flue gas dust extractor (cyclone separator) is not required in this
case.
The metal mesh filter comprises two block-shaped units joined
together. The compact design enables it to also be used in low level
boiler rooms. The filter cartridges are robust and resistant to a shower
of sparks.
Function:
The filter is operated with underpressure. With the cylindrical filter car-
tridges, the flow is from outside in. The filter cartridges are protected
against condensation by means of a heating system and are therefore
protected against corrosion. In the case of boiler demand, the filter
cartridges are preheated. If the set filter temperature is reached, boiler
start-up operation is enabled. If the temperature falls below the set filter
temperature, the filter heating system starts in heating mode. The fil-
ters are cleaned automatically in the countercurrent. This means that
the dust layer on the mesh is regularly discarded into the ash box.
Filter operation is controlled via the boiler control unit. Operation is
carried out via the control unit programming module.
