Factors Affecting Thermal Cracking Efficiency of Main Furnace

Factors Affecting Thermal Cracking Efficiency of Main Furnace

Heating Temperature

The reaction temperature inside the furnace directly determines the cracking speed. Insufficient temperature leads to incomplete cracking of raw materials and low oil yield. Excessively high temperature will cause carbonization and coking of oil and gas, which reduces efficiency instead.

Heating-up Rate

Too fast heating-up will cause local overheating and coking of materials. Too slow heating-up will prolong the reaction time and reduce overall production capacity.

Raw Material Loading Capacity

Overloading results in insufficient reaction space inside the furnace and poor oil-gas circulation, leading to incomplete cracking. Underloading causes low heat utilization of the furnace and low output per batch.

Anaerobic Closed Environment inside Furnace

Air infiltration due to poor sealing is prone to combustion and coking, which destroys the cracking environment and greatly reduces oil yield.

Type and Moisture Content of Raw Materials

Excessive moisture in raw materials consumes a large amount of heat and slows down temperature rise. Different raw materials have different cracking difficulty, which directly affects reaction speed and oil yield.

Heat Insulation Performance

Poor heat insulation of the furnace causes rapid heat loss, unstable furnace temperature, low heat energy utilization, and deteriorated cracking efficiency.

Smoothness of Oil and Gas Discharge

Blockage of oil-gas pipelines and poor exhaust will lead to high internal furnace pressure, which restricts the continuous progress of thermal cracking reaction.
