Energy/Power Generation Applications
 A typical plant involves numerous bulk solids handling systems. The fuel is often received by rail, barge, or overland conveyor. It is stockpiled at the plant, then reclaimed and conveyed into silos, bins, and/or bunkers, after which it is fed into a mill or directly into the combustion zone. The residues of combustion—both bottom ash and fly ash—are collected in cyclones, baghouses, and electrostatic precipitators and then usually stored in large silos. Many plants also store and handle lime or limestone, which is either fed directly into the combustor (fluidized bed applications) or mixed with the exiting flue gas as a dry mixture for dry scrubbing or as a slurry with water for wet scrubbing.
Given the variety of fossil fuels (e.g., bituminous coal, lignite, anthracite culm, bituminous gob, and petroleum coke) as well as the varieties of lime, limestone, and ash handled at coal-fired plants, numerous flow problems (often leading to structural problems) occur.
Jenike & Johanson helps power plants keep bulk solids flowing reliably while complying with regulatory requirements. We also give power companies a significant edge in a competitive, deregulated industry by modifying their bulk solids handling methods to increase process efficiency and substantially reduce operating costs. Contact Jenike & Johanson to discuss how your handling system can work to improve your bottom line.  Some of the energy/power generation problems we have analyzed and solved:

To meet the standards of the Clean Air Act, many power plants have been switching to low-sulphur sub-bituminous coal. Unfortunately, this cohesive, poorly-flowing coal often produces severe flow problems, such as stagnation during handling in silos and bunkers. One extreme consequence of this is spontaneous combustion. Other plants are installing flue gas desulphurization (FGD) systems, otherwise known as scrubbers. These require new, massive storage facilities for lime or limestone along with fly ash, and, in some cases, synthetic gypsum.
