What’s coal reburning?

Coal reburning is a process that turns burnt coal components into energy. The micronized procedure involves adding a row of charcoal burners above the main burn area, resulting in higher temperature and increased fuel. Reburning coal also breaks down nitrogen oxide, making it more efficient and reducing emissions. The process has become more popular as technology improves.

Coal reburning is a process that allows the broken down components of burnt coal to be used as a means of generating additional energy. This process effectively transforms what was once a waste product into another source of energy. While several methods have been employed to create a coal burning process, technology continues to improve the process and further increase the value of coal as an energy source.

One of the current methods used for the recombustion of coal is the micronized procedure. Typically, this technique involves installing an additional row of charcoal burners into an existing furnace. The row is located above the main burn area for the kiln and filled with charcoal that has been ground to a finer consistency than talc. This micronized charcoal powder is enriched with a small amount of oxygen, which helps improve the combustion process. The result is a higher temperature produced during a single burn session, which converts into more fuel for the furnace-fired equipment.

The benefits of reburning coal are not limited to simply using the coal dust to generate additional energy. Along with the direct increase in production resulting from the inclusion of dust in the combustion process, coal dust also breaks down the additional nitrogen oxide found in the main chamber of the furnace. This more efficient management of NOx leads to a substantial increase in combustion creation within the chamber. Depending on the efficiency of the individual furnace, re-combustion of coal can be used as a means of halving the amount of nitric oxide released compared to that produced in a conventional boiler.

Coal reburning has become a highly efficient means of using the residues created by the initial use of the mined coal. By employing the process of re-combusting coal dust, the energy output of this limited resource can be significantly increased. As technology has continued to refine the process, more companies that rely on the use of coal have modified their furnaces to allow for the recombustion process.
