The Quantification of an Overdesign Factor for Coal Preparation Plants
Coal Preparation, 1984This report describes a quantitative method for calculating overdesign factors for coal preparation plant design. A Monte Carlo technique was used to account for uncertainties in design data and plant operation, and a statistical consideration of possible plant performance enables the selection of an appropriate overdesign factor with respect to the ...

Technological Evaluation of Work of Coal Preparation Plants
2016The performed technological analysis of qualitative and quantitative operation performance of coal preparation plants of Ukraine for 23 years as compared with the reference analysis of 1990, which had shown that the power complex operates with concentrate yield loss, which tends to decrease, though. The coke complex operates with positive balance.

Alloy Corrosion and Erosion in Coal Preparation Plants
Corrosion, 1991Piping and other hardware in coal preparation plants are susceptible to degradation by dissolved salts and suspended coal in the process water. Because the coal mined underground in Appalachia and the Midwest is now increasing in chlorine content, there could be an adverse impact on materials performance.

Coal Preparation Plant Design Requirements for 2050
2016Coal preparation technology has come a long way in the past 35 years. Larger unit operations with enhanced efficiency, increased availability and new technologies in fines processing have been developed and implemented on a global scale in this timeframe. But where to for the next 35 years? This paper proposes the concept of developing an operator-free
