Coal – Microwave Pre / Post combustion
Development, deployment and technical support for unique and patented pre- and post-combustion coal upgrade technology.
Pre combustion coal upgrade technology includes the following two parameters:
1. Dewatering – the partial or total removal of moisture to increase the heat value of the coal, and
2. Demineralization – the partial or total removal of coal mineral content
Microwave pre combustion treatment of coal proved to dewater the coal to a very small level and demineralize coal minerals. The extent to which dewatering and demineralizing raw coal prior to combustion depends on many parameters, but is mostly determined by the specific economic situation in each separate case.
The post combustion treatment refers to effluent processing rather than coal, which is converted during combustion to various elements, most importantly the conversion of coal to heat and the release of carbon dioxide (CO2) in the process.
Post combustion processes include flue gas desulfurization FGD, particle collection, electric precipitators, and more recently the removal of CO2 from the flue gas. This gains a lot of attention recently, and is one of the most important points of attention for the industry.
Since coal is not only used for power generation, but also for other processes such as cement and lime production, steel making and others, the application of such pre and post combustion treatment is very widely spread.
Coal as the major source of prime energy will only increase in importance at least until 2050, and coal processing is the focus of much interest from Government and Private Sectors.
