The modern application of fire can be seen in the internal combustion engine. Thermal power stations use the heat generated by the combustion of fuels to boil water and drive turbines. A large percentage of the world’s population is supplied with electricity by these stations. In these situations, fire is a major contributor to a wide variety of modern technologies. The following article examines the properties of fire and how to safely put out a fire. But before you do anything, consider the importance of learning the details about fire.
Color of a flame
Several factors determine the color of a flame. One of these factors is the type of fuel used. Another factor is whether you’re looking at it with your naked eye or through a filter. Note what you see and take pictures to illustrate your findings. Note that results will vary depending on the method you use and the purity of the sample. This article explores several methods of determining the color of a flame. But before you begin, you should understand the basics of the flame.
Chemical composition of a flame
A good understanding of the chemical composition of a flame can help in preventing fires. Various studies have demonstrated that flames are composed of various components, including hydrogen, a mix of oxygen and nitrogen, and carbon dioxide. Studies on supposedly diffusion flames have shown that they resemble premixed systems. A methane flame, for instance, shows a concentration of both H and N2 near the fuel column. Candle flames of polymethylmethacrylate also show appreciable amounts of argon derived from the argon-oxygen atmosphere surrounding the burning fuel. The presence of this element may indicate that the flame is incompletely burning.
Rate of spread
The rate at which a fire spreads is directly related to the amount of fine dead fuel that is present in the area. When fine dead fuel contains 10% of the relative humidity of the area, the flame length of the fire is two feet. If the relative humidity of the area increases to 2%, the length of the flame is increased to five chains per hour. The flame length also increases with the rate of fire spread. When the fire is in an area that is surrounded by vegetation, the rate of fire spread is higher than that of grass.
Extinguishing a fire
First, you must understand what fire is. Fire is a chemical reaction, and there are three parts to a fire: cause, heat, and oxygen. Fires can be controlled by following the steps in this article. You should also know that fire is dangerous. However, you should not attempt to put out a fire on your own if you are not a professional. If you are not sure whether or not the fire is safe to deal with, contact a fire department in your area to get expert advice.
Controlling a fire
Defensible space is an area that has been cleared of flammable materials such as brush and vegetation. Indirect method is an alternative to direct method which aims to minimize the spread of the fire. It involves the use of two hoses with a fog nozzle and a solid stream of water. It is used only for fires where there is high wind. The general staff reports to the incident commander. Indirect method aims to contain the fire before it spreads beyond the control line.
