What effect does extending the coking time have on the furnace? ? ?

Our factory's late-stage coke oven has been around for more than 30 years. Now that the financial crisis has forced us to extend the coking time, I would like to ask you friends, what impact does extending the coking time have on the furnace? ? ? Especially for late furnaces.
The harm to the furnace body caused by extending the coking time: It is easy to cause leakage in the furnace body.
1. The burner is prone to low temperatures, so ensure that the burner has a higher temperature. 2. Coke is prone to overheating. Under the premise of ensuring the burner temperature, set a suitable standard temperature. 3. The furnace body will be impacted by cold shrinkage, and the spring tonnage should be larger. 4. The heat dissipation of the furnace body increases relatively. 5. The straight-line uniformity is reduced. 6. It will reduce the service life of the coke oven. measure: 1. The loose parts of the burner head must be grouted and sprayed. 2. The sealing wall of the regenerator and the exhaust pipe socket must be sealed and insulated. 3. The pressure of the gas collecting pipe should be increased. 4. When reducing the flow rate, replace the branch pipe orifice plate to maintain appropriate gas pressure. 5. Plan the focus push when the focus time is extended.
The main problem is the burner head and series leakage. It seems that the 30 years have reached the last few years of the coke oven's life. So your daily operation is still okay.
Extending the coking time is still beneficial to late-stage coke ovens. The main problem is the increase in furnace leakage.
Prolonging the coking time, the main problem is increased furnace leakage
Be sure to pay attention to the adjustment of iron parts, especially the tonnage of large and small springs and vertical and horizontal braces. It must be adjusted in time. Pay attention to the changes in the seams between the furnaces and repair them in time. The top wire of the furnace column should also be adjusted to ensure the curvature of the furnace column.
