What are the influencing factors in the process of polymeric heat transfer?

Material of the reactor and jacket, cooling water temperature and flow rate, degree of scaling in the jacket, sticking to the interior walls of the reactor, stirring speed, water addition during operation

Formula...........................................

Thermal polymerization occurs as a result of the heating oil being heated during the operation of the heating system; this reaction produces high-molecular-weight, high-boiling substances such as polycyclic aromatic hydrocarbons, gums, and asphaltenes, which gradually deposit on the surfaces of the heaters and pipelines, leading to coking. The thermal oxidation reaction occurs mainly due to the heat transfer oil in the expansion tank of an open heating system coming into contact with air or being involved in the circulation process. This reaction generates acidic compounds such as low-molecular-weight or high-molecular-weight alcohols, aldehydes, ketones, and acids; it also produces viscous substances like gums and asphalts, ultimately leading to coking ； Thermal oxidation is caused by abnormal conditions; once it occurs, it accelerates thermal cracking and thermal polymerization reactions, leading to a rapid increase in viscosity, a decrease in heat transfer efficiency, overheating, and coking of the furnace tubes. The acidic substances produced can also cause equipment corrosion and leaks.

Midway water injection, as well as the position of the jacket baffle valve

Too fine resin particles can also reduce the heat transfer coefficient.
