The phrase "ash formation" is correct and usable in written English.
It can be used in contexts related to geology, volcanology, or any discussion involving the creation of ash, such as from volcanic eruptions or combustion processes.
Example: "The study focused on the processes involved in ash formation during the eruption of the volcano."
Alternatives: "ash production" or "ash generation".
A laboratory method was developed earlier for determining the coal ash formation characteristics with the ash formation database for six coal types.
This procedure is based on the experimental results of primary fragmentation, burnout and ash formation of coal, using wen-chen hydrodynamic model.
The ash pellet was doped with heavy metals such as Cr, Cd and Pb prior to the combustion in order to establish their behavior during ash formation.
Because of the large fraction of ash in bed inventory, the ash formation data, i.e. ash initial size distribution, fragment and attrition characteristic, are of significance to determine the design parameters of a CFB boiler.
This paper suggests an approach where detailed information on ash composition and predicted ash formation reactions are basis for successful remedies enabling the use of fuels considered to be difficult.
This model emphasizes on the important factors that influence the ash balance in CFB boilers, such as ash formation, attrition and size reduction, residence time and segregation in dense bed.
The properties of coarse (>1 μm) particles have also been studied; both their chemical composition and size distribution are consistent with the break-up model of fly-ash formation.
The fuel composition and ash particle formation were simulated with synthetic ash particles (SAP) generated by aerosol methods.
The possibility of ash layer formation in the kinetically controlled regime is discussed.
The Ash Hollow Formation (AHF) of the Ogallala Group is an important sedimentary archive of the emergence of the Great Plains and it contains major groundwater resources.
The influence of probe exposure time and probe surface temperature (500, 560, and 700°C) on ash deposit formation rate was investigated.
