Combustion equipment burns fuel with oxygen to produce energy. Types include furnaces, boilers, turbines, and engines, which use different fuel sources such as oil, gas, coal, or wood. Furnaces produce thermal, mechanical, or electrical energy, while boilers produce steam or heated water. Turbines use gas or liquid to rotate blades and engines ignite fuel to […]
Heat of combustion is the energy released when a substance is burned in an oxygen-rich environment, expressed as kJ/mol or energy per volume/mass. Hydrocarbons release stored energy as heat and light. Enthalpy is sometimes used in the definition. Heat of combustion values are used to compare fuels, measured using a calorimeter. Heat of combustion is […]
Internal combustion engines use controlled explosions to generate mechanical energy, powering trains, planes, and cars. They have components that vary depending on the engine type, and can generate high levels of pollution. Before internal combustion, external combustion engines like steam engines were used. Internal combustion is literally the driving force behind trains, planes and cars. […]
Fuel combustion is a process where a hydrocarbon fuel reacts with oxygen to release heat and light. Fossil fuels like oil, coal, and natural gas are commonly used for energy production. Fuel injectors help control the reaction for safety and efficiency. Solid, liquid, and gaseous fuels can be used, but combustion of fossil fuels produces […]
Hydrogen combustion is a process where hydrogen reacts with an oxidizing agent to release thermal energy. It requires energy input to initiate the reaction and produces water vapor and heat. Hydrogen has potential as a clean and renewable energy source, but its efficiency is limited. Hydrogen-based fuel cells are being developed for various applications. The […]
Complete combustion occurs when all carbon atoms in a substance are consumed by a reaction with oxygen and heat, resulting in carbon dioxide and water. Incomplete combustion occurs when there is not enough oxygen, resulting in the release of gas and potentially dangerous carbon monoxide. Different materials have different ignition temperatures and burn thresholds, and […]
Combustion requires fuel, oxygen, and heat to start a chemical reaction. Fuel contains potential energy, and each fuel has a specific energy density. Oxygen can come from air or other oxidizing agents. Heat is what starts the combustion process, and once it starts, additional heat is not always needed. Combustion can release exhaust, including particulates […]
Ethanol is a commonly used substance for combustion due to its ease of production and low emission of pollutants. It is often used in vehicle engines and ethanol burners, which produce heat and light. However, it produces less heat energy than other fuels. Combustion is a term that simply means the burning of things. It […]
Chemical loop combustion uses metal oxides instead of air in the combustion process, resulting in simplified exhaust gases. In chemical ring combustion, metal oxides are circulated between two reactors to oxidize fuel. Oxyfuel combustion separates oxygen from air, simplifying chemical reactions. Chemical loop combustion is advantageous for carbon sequestration. Chemical cycle combustion is a technique […]
Chemical loop combustion uses metal oxides instead of air for fuel combustion, with offgases primarily consisting of CO2 and water vapor. Chemical ring combustion involves two interconnected reactors, with metal oxides used to oxidize fuel. This simplifies exhaust gas content, making it easier and cheaper to sequester carbon dioxide. Chemical cycle combustion is a technique […]
Combustion analysis is a method used in chemistry to determine the atomic composition of a substance by burning it under controlled conditions. It helps to determine the empirical formula of the sample, which shows the type and relative numbers of atoms. However, it does not provide information about the molecular or structural formula. It is […]
Combustion emissions, often from fossil fuels, include carbon monoxide, carbon dioxide, and nitrous oxide. Carbon dioxide is a greenhouse gas and can cause global warming, while carbon monoxide can be deadly. Nitrous oxide creates smog and can worsen respiratory conditions. Efforts are being made to reduce these emissions, but current methods are not effective against […]
Combustion chemistry studies how things burn through chemical reactions that produce heat and light. It explores types of reactions, combustion efficiency, energy generation, safety, and prevention of unintentional burning. Researchers work in labs and collaborate with organizations to advance chemistry and develop safety protocols. Students can pursue this field in colleges and universities with dedicated […]
Combustion systems use fuel and oxidizers to create energy through chemical reactions. Examples include boilers, fireplaces, and engines. Different combustion techniques and fuel types can be used. Combustion systems are chemical reactions between a material that can be burned as a fuel and chemical compounds present in oxidizers, substances that transfer oxygen atoms. The main […]
Boiler combustion is the process of burning fuels to produce steam for various applications. Different fuels can be used, and maximizing combustion efficiency is important for proper operation. Proper insulation, pipe design, and controls can improve efficiency, and monitoring oxygen and flue gas concentrations can optimize performance. Automatic controls are beneficial for boilers with varying […]
External combustion is a process where fuel is burned outside a device to power it. It can use any type of fuel and is mainly used in electricity production and military equipment. It has advantages such as reducing reliance on fossil fuels and pollutant emissions, but it is not widely adopted and has not been […]
Spontaneous human combustion (SHC) is a controversial phenomenon where the human body catches fire without an external ignition source. Victims are incinerated completely, with localized fire damage and incoherent burns. The wick theory suggests that clothes impregnated with body fat act as a slow-burning wick, but critics argue it does not account for an ignition […]
Combustion reactions release energy in the form of heat and light when a fuel and oxidizing agent react. Oxidation involves removing electrons from a substance, often involving oxygen. Spontaneous combustion can occur if the oxidizing agent is strong enough and the fuel ignites easily. Combustion products are typically oxides, and incomplete combustion can produce toxic […]
Combustion tests assess the safety and efficiency of fuel-operated appliances, including vent systems and fuel lines. Technicians visually inspect equipment and ventilation systems, check air quality, and perform burn tests to evaluate fuel efficiency and air flow. High levels of CO or CO2 can occur in airtight buildings, and net chimney temperature is also evaluated. […]
A combustion turbine compresses air, mixes it with gas or oil, ignites it, and drives a turbine to produce energy. Efficiency can be improved with regenerators, intercoolers, and duct burners. Climate and altitude can affect efficiency. Nitric oxide and carbon monoxide emissions can be reduced with SCR components. A combustion turbine is a machine that […]
