Sentence examples for coal combustion process from inspiring English sources

As Britain is now importing more than 40m tonnes of coal a year, his arguments cannot be dismissed out of hand – although, of course, we need a clean coal combustion process.

In the work, tire ash after coal combustion process is attempted for a binder in construction material.

Decoupling combustion realized by dividing the coal combustion process into coal pyrolysis and the combustion of volatiles and char can reduce NO emission from coal fired stoves.

In addition to the experimental study, a thermodynamic calculation was carried out to simulate the heavy metal speciation during coal combustion process.

For accurate modeling of the coal combustion process at elevated pressures, account must be made for variations in char-particle structure.

Within the computational methods used for the prediction of unburned carbon, coal combustion kinetics models, generally developed from the study of the real combustion process in experimental facilities, has the advantage to simulate the coal combustion process in a very realistic way.

Ultimately, however, clean-coal technologies fall into three categories: pre-combustion processing of coal; combustion processes that burn coal more cleanly; and post-combustion processes that scrub the exhausts.The most widely used clean-coal technologies are post-combustion scrubbers that cleanse exhausts of sulphur dioxide and nitrogen oxides.

Accelerating accumulation of fly ash, a byproduct in coal combustion processes, is of major environmental concern at present.

The achieved overall agreement between the experimental data and the numerical predictions, in terms of particle temperature and burnout times, highlights the capability of the model to simulate the effect of different operating conditions in the coal combustion processes.

Thereby two issues are especially addressed: (1) how LES and RANS impact differently the predictions of combustion properties even though, in both approaches, the same kinetic rates are used to represent the coal combustion processes; (2) how the numerical multiphase treatments may affect the prediction of micro-process interaction as well as the range in which these processes are not negligible.

In this paper, characterization of the flue gas recycle (FGR) is conducted for an oxy-coal combustion process.
