Hydrogen burning fuses hydrogen nuclei into helium in stars, creating heavier elements in their cores. Star formation occurs in interstellar gas clouds, with the birth of a star occurring when hydrogen ignites. The more massive the star, the faster it burns its fuel, with the hydrogen burning phase lasting up to nine billion years in […]
Diesel combustion uses compressed air and fuel to ignite and power an engine, without the need for a spark plug. The fuel is injected into the combustion chamber and vaporized by the heat, powering the crankshaft. Diesel engines are more fuel-efficient and can handle higher compression levels. The diesel engine was invented by Rudolf Diesel […]
Carbon burning is a nuclear reaction that occurs in the core of massive stars. It only begins towards the end of a star’s life and requires at least four solar masses. The process produces elements heavier than carbon and can lead to the formation of a red supergiant or a planetary nebula. The carbon burning […]
Combustion efficiency measures how well a device consumes fuel, with 100% being ideal but impossible. Parameters include fuel composition, oxygen levels, and gas leaving the device. Efficient devices are cheaper, less wasteful, and less harmful. Monitoring can increase efficiency, saving money and reducing pollution. Combustion efficiency is a measure of how efficiently a device consumes […]
The combustion chamber is where fuel is burned in an engine. In internal combustion engines, fuel is burned above the pistons, while external combustion engines burn fuel in a separate space. Internal combustion engines are efficient and used in mobile vehicles, while external combustion engines were used in steamships and trains. Both types of engines […]
Propane ignites on contact with oxygen, producing water and carbon dioxide. Combustion requires a spark or hot air. Incomplete combustion can produce poisonous carbon monoxide. Propane is used in grills, engines, and various heaters, and can be cheaper and cleaner than gasoline. It is also used in petrochemical production, semiconductor manufacturing, and hot air balloons. […]
Combustion can produce different products depending on the materials available. Clean combustion produces CO2, H2O, and energy, while incomplete combustion can produce CO, soot, nitrogen oxides, HCN, and NH3. Oxygen-free environments produce different products, including soot and CO. Nitrogen, halogens, sulfur, and phosphorus can also produce their own combustion products. The heat release potential and […]
Burn rate refers to the amount of loss incurred when insured property is destroyed compared to the amount of insurance protection guaranteed for that property. It helps individuals and businesses determine how much insurance coverage needs to be secured and maintained to cover total loss. Insurance companies use burn rate to set limits on coverage […]
