In order to start a thermoelectricity project, it is important to have a physical visit to the facilities in order to determine the waste heat ranges and the temperature in addition to the installation of the WHRU system.  The technical visit was made at the Distiller Company (Sta. Perpetua de la Mogoda, Barcelona) on May 9th, 2018.

Heat Source

After analyzing all the heat generation points of the facilities it was decided to explore several points, specially the WOGA oil boiler.

Conclusion

According to the visit made, it is considered that the chimney of the output gases of the WOGA boiler can be a suitable place for the placement of the WHRU units.

The temperature display on the electrical panel of the boiler indicates a temperature of the WOLGA boiler outlet gases of 270ºC but the real range is about 200ºC.

Flue gas outlet duct dimensions and sheet thickness will be requested.

WHRUs must be installed in the upper part of the flue gas outlet duct. We should have water at that point. According to what was discussed with Head of the Plant Maintenance,  there will be no problem in having a continuous amount of water to help dissipate the heat and achieve a greater temperature differential and thus obtain higher yields from our equipment. The flow, pressure and temperature data of the cooling water must be available.

The client uses the use of his WIFI for communication with the outside.

Working hours of the plant: from Sunday at 10pm until Friday at 10pm (120h / set. For 220 days / year).
