PREDICTION METHOD, DEVICE AND PROGRAM FOR INLET TEMPERATURE AT CRUSHER OF CIRCULATORY SYSTEM PULVERIZATION PLANT, AND COMPUTING METHOD, DEVICE AND PROGRAM FOR RAW MATERIAL SUPPLY AMOUNT

摘要

PROBLEM TO BE SOLVED: To enable an inlet temperature of crusher at crusher of circulatory system pulverization plant to be predicted in high accuracy.;SOLUTION: This invention relates to a circulatory system pulverization plant comprising a heat gas generating device, a mill and a bag filter in which a part of exhaust gas got from the bag filter is diffused into atmospheric air and circulated to the heat gas generating device under application of a circulation fan. A mill inlet temperature T_IN is computed on the basis of a heat balance for making-up a calory ΔQ_HGG generated by a burner, a workload ΔQ_FAN by the circulation fan and an exhaust heat quantity by diffusion of exhaust gas into the atmospheric air by an equation(102), Cx(F_bug-F_exh)(TI_N T_OUT)=ΔQ_HGG+ΔQF_AN+CxF_exhx(T_OUT-T₀)---(102) under application of a specific heat C of gas, a bag filter outlet exhaust gas flow rate F_bug, a diffusion gas flow rate F_exh, a mill outlet temperature T_OUT and ambient temperature T₀.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
