The reason for the high temperature in the cross-section of the pyrolyzer is excessive air supply ( ). Correct. +5 points for explanation. +10 points
Correct. The oxygen content should be controlled; the flue dampers should be closed, as well as the opening of the primary air dampers and the bottom air dampers.
The reason for the high temperature in the cross-section of the cracking furnace is excessive air; it is necessary to control the oxygen content, reduce the opening of the flue dampers, as well as the opening of the primary air valves and the bottom air valves
The reason for the high temperature in the cross-section of the pyrolyzer is excessive air (True)
The oxygen level is too high, resulting in strong negative pressure. The heat from the radiant section rises, leading to convection and thus an increase in the flue gas temperature; as a result, more fuel gas is required in the pyrolyzer, reducing its thermal efficiency.
