Document Type and Number:
Japanese Patent JP6702110
Kind Code:
B2
Abstract:
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 Tis computed on the basis of a heat balance for making-up a calory ΔQgenerated by a burner, a workload ΔQby the circulation fan and an exhaust heat quantity by diffusion of exhaust gas into the atmospheric air by an equation(102), Cx(F-F)(TIT)=ΔQ+ΔQF+CxFx(T-T)---(102) under application of a specific heat C of gas, a bag filter outlet exhaust gas flow rate F, a diffusion gas flow rate F, a mill outlet temperature Tand ambient temperature T.SELECTED DRAWING: Figure 2
