REKULUVO and REKUGAVO

REKULUVO and REKUGAVO Plate Heat Exchangers

The solution for gaseous media

{$pageoption_print}

The names "REKULUVO" (recuperative air pre-heater) and "REKUGAVO" (recuperative gas pre-heater) describe two highly efficient, fully welded plate heat exchangers for gaseous products, working according to the countercurrent principle. This system achieves very high heat recovery rates.

The heat transfer surfaces consist of profiled plates with a high specific capacity which are welded together into self-supporting packs. Both gases flow through the plates in countercurrent and are separated from each other without leakage. Mixing of the two gas streams is thus almost completely excluded.

Fields of application
The REKULUVO is particularly suitable for pre-heating the combustion air in petrochemical plants (fired heaters) or in methanol and ammonia plants.
The REKUGAVO is the perfect heat exchanger for heating up flue gas to the catalyst reaction temperature, e.g. in denitration units of refuse incinerating plants.

Technical data
The capacities are between 3,000 and 1,177,000 SCFM (5,000 and 2,000,000 Nm³/h). Air and flue gas in these volumes at up to a temperature of 1100°F (600°C) can be circulated without any problems, and the recovery rate is up to 97 %!
