Description

The parabolic or concentrated oven consists of a parabolic-shaped reflector. Its shiny mirror-effect surface captures the sun's rays, concentrates them, and then reflects them onto the cooking surface located on the grid.

Introduction

The solar concentrated oven is a device that uses a mirror-effect surface to concentrate solar light onto a very narrow focal point. This focal point can reach extremely high temperatures, up to several thousand degrees Celsius, making it a very powerful tool for producing thermal energy.

Concentrated solar ovens are considered a clean and sustainable energy source that can replace conventional energy sources such as fossil fuels.

Étape 1 - Preparation of the rolling stand

Use a rolling table, with a rectangular sheet that needs to be fixed with a drill and screws on the stand to place the tube that will support the parabolic dish later.

Étape 2 - Placement of the mirror film on the parabolic dish

Stick the mirror film onto the entire surface of the parabolic dish by cutting it into small pieces to prevent bubbles from forming.

Étape 3 - Attachment of the parabolic dish to the stand

Attach the parabolic dish to the stand using the wrenches.

English : Attach the parabolic dish to the stand using the wrenches.

Étape 4 - Preparation of the plate support

Use the metal part of the parabolic dish that allows you to adjust the angle to align the plate's orientation with that of the parabolic dish by aiming at the focal point that will allow us to cook. We needed two spacers to tighten the bar against the stand in order to change the angle of inclination of the plate and adjust it with the angle of the parabolic surface stand. A bent metal sheet (using a vise) was also used to secure the bar on the parabolic dish.

Étape 5 - Fixation de la grille / Grid attachment

Français : Découpez la grille de la taille qui vous convient et fixez la à l'aide des fils de cuivre.

English : Cut the grid to the desired size and secure it using copper wires.

Notes et références

Français : L'utilisation d'un four concentré solaire comporte certaines précautions pour garantir la sécurité des personnes et des équipements

• Rayonnement intense : La lumière solaire concentrée peut produire des niveaux dangereux de rayonnement ultraviolet et infrarouge, il est donc important de prendre des mesures de protection pour les yeux et la peau, telles que des lunettes de protection et des vêtements de protection.
• Équipements : Les équipements utilisés pour concentrer la lumière solaire, tels que les films à effet miroir, doivent être inspectés régulièrement pour s'assurer qu'ils sont en bon état et qu'ils fonctionnent correctement.
