The rubber industry is one of the important application areas of thermal oil boilers. The thermal oil heater plays a crucial role in the rubber industry, which is mainly used in the high-temperature vulcanization process of rubber products. It is necessary to place the rubber products in a thermal oil furnace to achieve the vulcanization temperature through the heat transfer effect of the thermal oil during the high-temperature vulcanization process of rubber products. Due to the rubber’s good thermoplastic and elastic properties, it is one of the raw materials for the production of various footwear such as sports shoes, leather shoes, rubber shoes, etc. Most rubber shoe processing techniques involve vulcanization, foaming, heat setting, drying, and so on. These processes require a large amount of sufficient thermal energy supply. It not only consumes a lot of energy, but also the temperature and pressure requirements of each process are also different. It should be noted that if the heating temperature is not standardized, it can also lead to serious consequences such as immature or over cooked rubber, and substandard shoe performance.
 
In recent years, Thailand has participated in multiple free trade agreements, and the production and supply capacity of the footwear industry for service exports has continuously improved. A large local shoe factory purchased a 17500kw YLW series coal fired thermal oil boiler from Sitong boiler for heating its production line after multiple researches. Sitong boiler provides this customer with a set of high-temperature and low-pressure coal-fired thermal oil heater. The thermal oil heater can achieve higher  temperatures at lower pressures compared to steam boilers. In the vulcanization process of rubber shoes, the temperature control system of the thermal oil boiler will be more accurate to ensure that the rubber products undergo vulcanization reaction at the appropriate temperature. And this YLW series coal fired thermal oil boiler from Sitong boiler has stable heating and excellent performance. The boiler system is equipped with a fully automatic control system, which can accurately control the working temperature and other important production parameters so that meet the temperature requirements of multiple processes in customer footwear processing. The picture shows the delivery site of the boiler.
