Benefits at a glance:
Flue gases contain significant heat potential at high  Increase of the boiler efficiency

efficient heat recovery surfaces utilise this heat potential  Easy retrofitting of existing systems
and thus increase the boiler efficiency of new or existing
steam boiler systems significantly. The flue gas heat
exchanger is installed downstream of the boiler and is
used for "dry" operation for heating up feed water. To
use the condensing heat, the flue gas condensation
can take place in an additional downstream flue gas
heat exchanger module and make-up water can be
heated up. The subsequent installation in existing
single-flame tube steam boiler systems can be carried
out very easily by these modules.

Construction
In the lower part, the flue gases are collected and flow
through the integrated heat exchanger in the upper
part for heat recovery.

Equipment level
The module is mounted on a stable base frame and has
rails at the back for transportation. Servo drive, piping
of the connections, flue gas control and drain shut-off

Steam distributor SD

In the distributor, the generated steam mass flow is
distributed to the consumer and residual moisture is
separated and drained.

Construction
A collecting pipe with an order-related number of pipe
outlets is fully assembled with flange connections and
all necessary fittings into a module unit.
