Title:
CRUSHED STATE DETERMINATION PROGRAM OF CRUSHING EQUIPMENT, COMBUSTION EFFICIENCY DETERMINATION PROGRAM OF COAL, CRUSHED STATE DETERMINATION DEVICE OF CRUSHING EQUIPMENT AND COMBUSTION EFFICIENCY DETERMINATION DEVICE OF COAL
Document Type and Number:
Japanese Patent JP2014159900
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a crushed state determination program of crushing equipment and a combustion efficiency determination program of coal capable of efficiently performing evaluation with a simple constitution in order to combust even low-quality coal stably and economically.SOLUTION: Inlet temperature or outlet temperature on crushing equipment is calculated from coal supply quantity data, raw material moisture amount data, hot air supply quantity data, and outlet temperature data or inlet temperature data which are acquired by using specific heat of coal raw material, specific heat of water, specific heat of air, vaporization latent heat and vaporization moisture amount vaporized on the crushing equipment which are stored in data base 41 for crushed state determination. When the calculated inlet temperature is higher than a standard inlet temperature or the outlet temperature is lower than a first standard outlet temperature by comparing the inlet temperature or the outlet temperature with the standard outlet temperature or the standard inlet temperature, it is determined that the crushing equipment cannot be stably operated and such an effect is notified.
