At the end of the operation life of a gasification furnace burner, at what pressure difference must it be replaced?
Thread Content
The burner in our plant’s 8.7 MPa gasification furnace has been in continuous operation for 45 days; currently the pressure difference across the burner is 200 KPA. Does it need to be replaced?
The burner pressure difference is not the only criterion for determining when a burner needs to be replaced, and the designed pressure difference varies for each model of burner. Whether the burner needs to be replaced should be determined through a comprehensive consideration of various factors such as the temperature at the upper cone end, the temperature of the furnace wall, and the condition of the slag. An initial assessment is made to determine whether there is a blockage in the burner, internal leakage in the burner, or wear on the nozzle, after which the burner is replaced accordingly.
