Abstract
Based on the instability caused by the change of coal quality
the changing characteristics of negative pressure and fire detecting under unstable combustion were researched and related theories were studied in depth.Furthermore
an unstable combustion prejudication model and criterion of unstable combustion were designed.It can remind the workers of intervening the combustion promptly
and reduce labor intensity and the possibility of flameout.It also can increase the economical efficiency of the thermal power generating units and increase the stability of power network operation.
