The agglomerated coal would be delivered to either of two locations, one being the stockpile, which meant handling by belt conveyor to the stacker/reclaimer, and the other being the bunker, which is serviced by a 200ton surge bin and belt conveyors. A simple test was performed on the agglomerated coal fines to confirm the dedusting efficiency.
A power plant illustrates how utility companies are applying tools to control coal quality, increase the availability of coal, and reduce the cost of generation without sacing boiler performance by blending low and highergrade coals.

Expert systems and coal quality in power generation 5 In 2011, approximately 40% of the world''s electricity will be generated from coal. Coal remains the most abundant fossil fuel and can therefore provide a reliable energy source for much of the next century. For a variety of reasons including, particularly, security of supply, it is almost ...

Coal Blending. RPM Solutions, based in Lexington, Kentucky, understands coal blending and specializes in it. Coal blending is the process of mixing coals after coal has been mined to achieve quality attributes that are desirable for the coal''s intended application (, steam generation and coking).
Coal Blending and Process Redesign for Steam Generation Plant 12 Project Scope The scope of the project covers the deliverables outlined in the document. Coal blending model An accurate coal blending model will be formulated with constraints and will form the basis for the coal blending .
Coal blending in power stations reduces the cost of generation and increases the availability of coal. Lowgrade coals can be mixed with better grade coal without deterioration in thermal performance of the boiler thus reducing the cost of generation, but there are many considerations before deciding to blend.
GammaMetrics Coal Blending Optimization System (COBOS) Although Thermo Electron has been providing blending software to the coal industry for more than 15 years, a recent product enhancement satisfies well the combined goals of system performance and user friendliness. The optimization algorithm minimizes the cost of the blend,

AllScan Onbelt Coal Analyser Use in Blending. In coalfired power generation in particular, blending of coals is undertaken to reduce the cost of generation and increase availability of coal. Lowgrade coals can be mixed with better grade coal without deterioration in thermal performance of the boiler thus reducing the cost of generation.
Coal with too much moisture, ash, or sulfur won''t meet boiler specifications and cause process inefficiencies and poor output. Online elemental coal analyzers, which measure sulfur, ash, moisture, calorific value, and all major ash constituents, help to ensure that each coal blend meets customer specifications. Online analysis can be ...
