Coal Blending: Business Value, Analysis, and Optimization
Coal blending is a critically important process in the coal mining industry as it directly influences the number of product tonnes and the total revenue generated by a mine site. Coal blending represents a challenging and complex problem with numerous blending possibilities, multiple constraints and competing objectives. At many mine sites, blending decisions are made using heuristics that have...
متن کاملModification of combustion behaviour and NO emissions by coal blending
Combustion profiles determined by TGA and experiments in a laminar entrained flow reactor (EFR) were used in this work to assess the relative combustion reactivities of different rank coals and their binary coal blends. The combustion behaviour of coal blends in TGA was greatly influenced by coal rank and the proportion of each component in the blend. Higher volatile coals exerted more influenc...
متن کاملA Blending and Inter-Modal Transportation Model for the Coal Distribution Problem
The problem of how to plan coal fuel blending and distribution from overseas coal sources to domestic power plants through some possible seaports by certain types of fleet in order to meet operational and environmental requirements is a complex task. The aspects under consideration includes each coal source contract’s supply, quality and price, each power plant’s demand, environmental requirem...
متن کاملBlending basics
This article serves as a primer for the theory of online meaning construction known alternately as conceptual blending, conceptual integration, the many space model, and the network theory. Our tutorial proceeds by analyzing novel and conventional examples of linguistic and nonlinguistic blends that pertain to topics of reference, partitioning, mapping, structure projection, and dynamic mental ...
متن کاملBlending margins
We investigate properties of the formula p → 2p in the basic modal logic K. We show that K satisfies an infinitary weak variant of the rule of margins, which leads to a description of a complete set of unifiers of p → 2p. Using this information, we establish that K has nullary unification type. Moreover, we show that the formula p → 2p is admissibly saturated, but not exact.
