One of the applications of coal as a fuel is the production of gas through circulating fluidized bed technology. The modeling of these systems allows verifying and optimizing the design and operation parameters of gasifiers ...

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 ...

The processes involved in coal preparation produce harmful effects for the environment, mainly by the quantity and nature Of wastes that are generated, These tailings generally called ""pyritic"", even though not presenting ...

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, ...

There are enormous resources of unconventional gas in coal measures in Ordos Basin. In order to study the geological characteristics of unconventional gas in coal Measures in Ordos Basin, we analyzed and summarized the ...

Understanding the ignition behaviour of coal is of utmost importance for the design of boilers and control of the combustion process. In recent years there has been an increasing utilisation of coal blends for combustion, ...
