Several reasons for the increase in the temperature of the process gas at the outlet of the gasifier: (), (), (), (), (). Several reasons for the increase in the temperature of the process gas at the outlet of the gasifier: (system overpressure), (decrease in the liquid level in the quench chamber), (reduced flow rate of quench water), (increase in the temperature of the combustion chamber), (increased amount of black water discharged).
System overpressure, reduced liquid level in the quench chamber, decreased flow rate of quench water, increased temperature in the combustion chamber
(System overpressure) (Decrease in quench chamber liquid level) (Reduced inflow of quench water), (Increase in combustion chamber temperature), (Increased discharge of black water).
(System overpressure), (decrease in quench chamber level), (reduced inflow of quench water), (increase in combustion chamber temperature), (increased discharge of black water).
High oxygen-to-coal ratio, low slurry concentration, low quench water volume, damaged downcomer, false surface indications
System overpressure, reduced liquid level in the quench chamber, decreased flow rate of quench water, and increased temperature in the combustion chamber
System overpressure, reduced liquid level in the quench chamber, decreased flow rate of quench water, increased temperature in the combustion chamber, increased amount of black water discharged
System overpressure, reduced liquid level in the quench chamber, decreased flow rate of quench water, increased temperature in the combustion chamber, increased amount of black water discharged

System overpressure: Temperature, Process, Outlet
The oxygen-to-coal ratio is too high, the flow rate of quench water (quench gas) is too low, the heat exchanger is clogged, the limestone ratio is inappropriate; the type of coal needs to be changed
