Overview

The flue gas heat exchanger is designed to save energy through lowering the flue gas temperature by heating the mains return water. Flue gas flow contains significant heat potential at high temperature. Economiser modules with their highly-efficient heat recovery surfaces utilise this heat potential and thus increase the boiler efficiency of new or existing steam boiler systems significantly. The downstream flue gas heat exchanger from the boiler is used for "dry" operation for heating up feed water. To use the condensing technology, 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 extremely easily by these modules.

ECO

Pros:

  • Increase of the boiler efficiency
  • Reduction of the fuel consumption
  • Easy retrofitting of existing systems

Additional properties

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 valves are fully assembled and included in the scope of delivery as well as thermal insulation ex works.
