Stability of low-load operation of the gasifier
Thread Content
What are the changes in parameters such as the oxygen-coal ratio, furnace wall temperature, and slag outlet pressure difference when a water-coal slurry gasifier operates at partial load, and what impact do these changes have on the equipment?
Operate at half load; if necessary, reduce the system operating pressure to ensure that all parameters are properly matched.
Yes, the system pressure is below normal levels
When the gasifier operates at low load, attention must be paid to the oxygen flow rate in the burners, as well as to appropriately reducing the system pressure. Since the dimensions of the slag outlet and downcomer remain constant, operating at low load results in higher coal consumption.
