Set of displacement rods
[Item No. KPT-V1250]
Installing the displacement rods in the heat exchanger pipes produces better heat transmission and thus lowering to a
great degree of the exhaust gas temperature. The displacement rods are advisable for fuels with water content less than
W40 and when the furnace is used to cover the base load.
Recommendation: only use with a pneumatic cleaning system.

Flue gas recirculation system
[Item No. KPT-R1250-S]
Function:
Exhaust gas is mixed into the combustion air. This increases the proportion of gases not involved in the incineration
(nitrogen N
2
and carbon dioxide CO
2
), with the effect of lowering the fire box temperature. This in turn enables, on the
one hand, maximum efficiencies with a low amount of excess air with dry fuels and, on the other hand, the incineration of
fuels that tend to form slag.
The following items come with the system:
-
Recirculated flue gas fan with a heat-resistant design instead of the two primary airflow fans
-
Suction line between furnace outlet and recirculated flue gas fan made of heat-resistant steel no: 1.4401
Incl. valves for regulating fresh air/recirculated gas
-
Pressure lines from the recirculated flue gas fan to the firing block
Incl. valves for splitting up the recirculated gas/air mixture to the internal and external grates
The two primary air fans for the standard design are omitted.
-
Software component in the control system
To be carried out by the customer:
-
Insulation of the recirculated gas line in the course of the general insulation work (fire tubes, heating tubes, etc)
