The Lighthouse of Alexandria, also known as the Pharos of Alexandria, likely used a combination of materials to keep its flame burning. While the exact fuel is not definitively known, it is believed that they used a mixture of wood and possibly oil, such as olive oil, which would have been readily available in the region. The use of reflective surfaces, possibly including polished metal, helped amplify the light from the flame, making it visible to ships far out at sea.
The original lighthouse at Alexandria, the Pharos, was one of the 7 Wonders of the Ancient World. Horses could pull wagons to the top of the structure to bring wood for fuel.
When fuel is burning, you typically see a flame producing light and heat as a result of the chemical reaction between the fuel and oxygen. The color and intensity of the flame can vary depending on the type of fuel being burned.
It depends on what fuel is burning.
A flame needs three things to keep burning: fuel (such as gas or wood), oxygen, and heat. When these three elements are present and in the right proportions, the flame will continue to burn.
A yellow flame typically indicates excess fuel in combustion. This happens when there's an incomplete burning of the fuel, leading to the presence of unburned fuel molecules that emit a yellow color.
A wick works by absorbing the melted wax in a candle and drawing it up to the flame, where it vaporizes and burns, providing fuel for the flame to continue burning.
Candle wax is made of hydrocarbons that vaporize when heated by the flame. These vapors mix with oxygen in the air and ignite, creating a continuous supply of fuel for the flame to burn. The wax also acts as a wick, drawing the liquid wax up to the flame where it vaporizes and continues the burning process.
Fuel, Oxygen and a spark to ignite the flame. Use the Fire triangle.
Well like with any flame, the lighter the flame, the higher the temperature of the flame. If the flam is burning Yellow, it is at a higher temperature and is burning more oxygen than an orange flame is. That is your difference other than the color.
The spectral properties of a flame refer to the visible light emitted when a hydrocarbon fuel burns. The color of the flame can indicate the temperature and the presence of certain elements in the fuel. Spectral analysis of the light emitted from a flame can be used to identify the chemical composition of the burning material.
Flame retention refers to the ability of a burner to maintain and stabilize a continuous flame during combustion. Good flame retention is important for efficient burning of fuel and reducing emissions in combustion systems.
Flame color is determined by the temperature at which the fuel is burning. They can therefore be many different colors. Nickel for example burns green. Even in the flame you see when burning a log, there is blue (and the obvious red yellow orange)
