Use of a fluidized bed combustor and thermogravimetric analyzer for the study of coal ignition temperature
(2017-01-01)
Ignition experiments with two bituminous coals were carried out in an atmospheric bubbling fluidized bed combustor (FBC) and a thermogravimetric analyzer (TGA). In the FBC tests, the rapid increase in O2, CO2, and ...
Atmospheric bubbling fluidized bed combustion: Application to high ash coals and approach to scientific research
(1996-06-01)
This work is concerned with research on atmospheric bubbling fluidized bed combustion (AFBC) applied to mineral coals of high ash content. Coals is considered in a scenario of power generation both domestic and world-wide, ...
A thermogravimetric analysis of the combustion of a Brazilian mineral coal
(Sociedade Brasileira de Química, 2008)
Knowledge of coal combustion kinetics is crucial for burner design. This work aims to contribute on this issue by determining the kinetics of a particular Brazilian bituminous coal. Non-isothermal thermogravimetry was ...
