What is a Class B fuel?
Class B – Flammable liquids: gasoline, oil, grease, acetone. Any non-metal in a liquid state, on fire.
What type of fuel is found in a Class B fire?
Class B fires involve flammable and combustible liquids such as gasoline, alcohol, oil-based paints, lacquers.
What are the 5 classes of fuels?
Fires can be classified in five different ways depending on the agent that fuels them: Class A, Class B, Class C, Class D, and Class K. Each type of fire involves different flammable materials and requires a special approach. In fact, trying to fight a blaze with the wrong method might make the situation worse.
What are Class C fuels?
Class C. The Class C fire is defined as a fire that uses electrical components and/or energized equipment as its fuel source. Electrical fires are often fueled by motors, appliances, and electronic transformers. To extinguish such fires you cut the power off and use non-conductive chemicals to extinguish the fire.
Which is not fuel?
Coal, oil and natural gas are examples of natural gas. Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen, usually consisting of certain quantities of methane and other constituents. Therefore, biogas is not a fossil fuel.
What is the most common fuel?
Gasoline is the most commonly used U.S. transportation fuel.
Which is the primary fuel?
Primary fuels are fuels that are found in nature and can be extracted, captured, cleaned, or graded without any sort of energy conversion or transformation process. Primary fuels such as coal should be distinguished from primary energy flows like wind and solar power.
Which one is not a primary fuel?
Notes: A primary fuel is that which is used in the same form as it occurs in nature. Kerosene is obtained by the fractional distillation of oil, and hence is a ‘secondary fuel’.
Which is the natural fuel?
Chemical
| Primary (natural) | Secondary (artificial) | |
|---|---|---|
| Solid fuels | wood, coal, peat, dung, etc. | coke, charcoal |
| Liquid fuels | petroleum | diesel, gasoline, kerosene, LPG, coal tar, naphtha, ethanol |
| Gaseous fuels | natural gas | hydrogen, propane, methane, coal gas, water gas, blast furnace gas, coke oven gas, CNG |
Where is this fuel obtained from?
Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth’s crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels.
What are the 4 main natural gases?
Water, ethane, butane, propane, pentanes, hydrogen sulphide, carbon dioxide, water vapor, and occasionally helium and nitrogen may be present in a natural gas well. In order to be used for energy, the methane is processed and separated from the other components.
Is natural gas pure?
Typical Composition of Natural Gas In its purest form, such as the natural gas that is delivered to your home, it is almost pure methane. Methane is a molecule made up of one carbon atom and four hydrogen atoms, and is referred to as CH4.
