Difference between biphenyl furnace and other heating equipment

In the field of industrial heating, biphenyl furnaces, thermal oil furnaces and steam heaters are common and efficient heating devices. However, they differ in terms of heating principle, application area and performance. Understanding the differences between these devices can help you choose the most suitable heating solution for your actual needs. The following is a detailed comparison of biphenyl furnaces with thermal oil furnaces and steam heaters.

1. Differences between biphenyl and thermal oil furnaces

Heating principle
Both biphenyl furnace and heat transfer oil furnace belong to indirect heating equipment, but the heat transfer medium of the two is different. Biphenyl furnaces mainly use biphenyl as the heat transfer medium, which is suitable for ultra-high temperature requirements, generally reaching high temperatures above 300°C, while thermal oil furnaces use thermal oil as the medium, which is suitable for working at relatively low temperatures (usually between 200-300°C). Due to the higher boiling point of biphenyl, it is able to remain liquid at higher temperatures and is suitable for scenarios with higher high temperature requirements.

Thermal efficiency and temperature control accuracy
Biphenyl furnaces have a high thermal efficiency at high temperatures and are able to reach the required temperature in a shorter period of time and maintain temperature stability. Although the thermal efficiency of thermal oil furnace is high, it is easy to oxidise at higher temperatures, leading to the decline in the performance of thermal oil and the shortening of its service life. In contrast, the biphenyl furnace's high-temperature resistance is more prominent, and can operate stably under long-term high-temperature conditions, reducing the frequency of equipment maintenance.

application scenario
Biphenyl furnaces are typically used in industrial processes requiring sustained high temperatures such as chemical, pharmaceutical and food processing, while thermal oil conductive furnaces are more commonly used in production processes with relatively low temperature requirements, such as textile, rubber and plastics heating. When choosing between these two types of equipment, the selection should be based on the temperature range and temperature control requirements in the production needs.

2. Differences between biphenyl furnaces and steam heaters

Heating principle
Steam heaters use the latent heat of water vapour to provide heat and are usually suitable for low to medium temperature applications, whereas biphenyl furnaces use biphenyl as a heat transfer medium to transfer heat and are suitable for higher temperature industrial needs. Steam heaters typically do not exceed 200°C, making it difficult to achieve the ultra-high temperature heating provided by biphenyl furnaces. For processes requiring high temperatures above 300°C, the advantages of biphenyl furnaces are even more obvious.

Temperature control accuracy
Biphenyl furnaces have a higher precision of temperature control and can maintain a stable output of ultra-high temperatures, whereas steam heaters are not suitable for applications sensitive to temperature variations due to the relatively large temperature variations as the heating process relies on the condensation and evaporation of water vapour. Biphenyl furnaces are more reliable in processes that require precise temperature control, and are suitable for applications in pharmaceutical, chemical and other fields with stringent temperature requirements.

Operating Costs and Maintenance
Steam heaters are usually less expensive, suitable for scenarios where ultra-high temperatures are not required, and have relatively low installation and maintenance costs, making them suitable for general use in small and medium-sized enterprises or factories. In contrast, biphenyl furnaces are more expensive to operate, but have a longer service life and the equipment is more stable at high temperatures, making them suitable for large-scale, continuous production applications.
