3 Million Kcal Coal Fired Thermic Fluid Heater Helps Vietnam Shoemaking Industry

Rubber has good thermoplastic and elasticity, it is one of the raw materials for producing sports shoes, leather shoes, rubber shoes and other footwear. Most of the rubber shoe manufacturing processes require a large amount of heat energy supply, and each process has different temperature and pressure requirements. If the heating temperature is not standard, it will also lead to undercooked or overcooked rubber and unqualified shoes.


Application analysis of thermal oil heater in shoemaking industry

In order to ensure the stability of heat supply, large shoe material factory choose self-provided thermic fluid heater for production heat supply. The working principle of the thermal oil boiler is to use the heat transfer oil as the medium, and use the hot oil circulating oil pump to force the medium to carry out liquid phase circulation, so as to transfer the heat energy to the heat equipment. Heat transfer oil has a large heat capacity, which can realize low-pressure and high-temperature heating, and the heating temperature reaches 320℃; also, the working temperature can be precisely controlled by an automatic control system.
