Definition von fly ash im Englisch Englisch wörterbuch
Fine particulate ash sent up by the combustion of a solid fuel, such as coal, and discharged as an airborne emission or recovered as a byproduct for various commercial uses
Ash drawn from the burning fuel and carried by the gas flow through the kiln chamber or flues
The airborne combustion residue from burning coal or other fuels Consists mainly of various oxides and silicates Major sources are pulvarized coal-burning boilers
A fine residue, left after trash is burned in an incinerator, which can be carried in the air It can contain harmful or toxic substances such as dioxins, lead and mercury
Particle matter from coal ash in which the particle diameter is less than 1 x 10-4 meter This is removed from the flue gas using flue gas particulate collectors such as fabric filters and electrostatic precipitators
A waste product from coal-fired power stations which can be used in concrete structures as a substitute for cement Fly ash can improve the properties of concrete, lower the cost to produce concrete and reduce the greenhouse emissions generated during the manufacture of cement
fine solid particles of ash that are carried into the air when fuel is combusted
Noncombustible residue from the combustion process, carried by flue gas Depending on its composition, it can be a hazardous waste
Non-combustible residual particles expelled by flue gas The by-product of coal burning; it is persistent in the atmosphere
are air-borne solid particles that result from the burning of coal and other solid fuel
the highly toxic particulate matter captured from the flue gas of an incinerator by the air pollution control system
A type of pozzolan suspended in flue gases during coal combustion, from which it is collected Most commonly used to replace 15%-30% of Portland cement in a mix conforming to ASTM C618 Classified as either Class F or Class C, according to the regional type of coal burnt to produce it Fly ash is also used for fill material, soil stabilization and waste remediation
Ash particles, frequently in the form of small, irregular flakes, that escape into the atmosphere and quite rapidly settle to the ground
The finely divided particles of ash suspended in gases resulting from the combustion of fuel Electrostatic precipitators are used to remove fly ash from the gases prior to the release from a power plant's smokestack
Fine solid particles of ashes, dust, and soot carried out from burning fuel (as coal or oil) by a draft This pozzolanic material consists mainly of silicon and aluminum compounds that, when mixed with lime and water, forms a hardened cementitious mass capable of obtaining high compression strengths
The noncombustible particles in flue gas Often used as a body feed or solidification chemical
Gas-borne particulate resulting from the combustion of fuels, typically fossil fuels such as coal and lignite The ash is composed of a variety of oxides and silicates depending on the fuel and efficiency of the combustion process
[ 'flI ] (verb.) before 12th century. Middle English flien, from Old English flEogan; akin to Old High German fliogan to fly and probably Old English flOwan to flow.
