Nuclear fuel - Wikipedia

Nuclear fuel - Wikipedia

Nuclear fuel is material used in nuclear power stations to produce heat to power turbines.Heat is created when nuclear fuel undergoes nuclear fission.. Most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission.The three most relevant fissile isotopes are uranium-233, uranium-235 and plutonium-239.

How Do Cars Run on Chemical Reactions? | It Still Runs

Inside the engine, the gas is sprayed into the combustion chamber above the piston. It is mixed with oxygen and then ignited. The reaction -- basically a little explosion -- heats it all up, making the air expand and push the piston outward. This is how the engine converts the gasoline's chemical energy into mechanical force.

This study presents an experimental demonstration of pressurized chemical looping combustion (CLC) in an internally circulating reactor (ICR). The ICR concept is a novel alternative to the conventional interconnected fluidized bed CLC configuration as it eliminates all cyclones, loop seals and solids transport lines, and it can be pressurized in a single pressure shell.

Chemical to Thermal | EGEE 401: Energy in a Changing World

Energy is required to break the chemical bonds in the fuel (an endothermic process). When the new chemical bonds are formed, energy is released (an exothermic process). In combustion, more energy is released from the new bonds than is required to break the old bonds. This excess energy keeps the reaction going and produces heat and light.

Cool flame - Wikipedia

Cool flame - Wikipedia

A cool flame is a flame having maximal temperature below about 400 °C (752 °F). It is usually produced in a chemical reaction of a certain fuel-air mixture.
