Possible Reasons for the Slow Cooling of Pyrolysis Furnace

　　1: Good insulation performance of the furnace: In order to improve thermal efficiency, the furnace body of the pyrolysis plant is usually insulated with refractory materials and insulation layers, which will make it difficult for heat to dissipate and prolong the cooling time.

　　2: Unreasonable design of the cooling system: The cooling system is a key factor affecting the cooling speed. If the cooling system is not designed reasonably, such as insufficient air volume and unreasonable air duct design, it will lead to low cooling efficiency.

　　3: High temperature of the environment: High temperature will reduce heat exchange efficiency.

　　4: Too much feedstock in the furnace: The more materials in the furnace,the more heat is stored,and the longer it takes to cool down.

　　5: Improper operation: For example, the cooling speed will be affected if the exhaust port is not opened in time.
