2.?Operating Principle of Thermal Oil Boilers

2.1 Basic Definition of Thermal Oil Boilers

A thermal oil boiler is a heating system that utilizes thermal oil as the heat transfer medium, achieved through the combustion of fuel. Unlike conventional steam boilers, thermal oil boilers provide high-temperature heating at lower pressures, offering benefits like enhanced efficiency, safety, and stability. These boilers are extensively used across various industries, including petroleum, chemical, pharmaceutical, and food processing.

2.2 Main Components of Thermal Oil Boilers

The main components of a thermal oil boiler include the burner, thermal oil furnace body, circulation pump, expansion tank, temperature control system, and safety devices. The burner mixes fuel (such as natural gas, diesel, or coal) with air and ignites it, producing high-temperature flames that heat the thermal oil. The furnace body contains coils or serpentine pipes where the thermal oil flows and absorbs heat. The circulation pump drives the thermal oil through the system, ensuring heat is transferred to various heating points.

2.3 How Do Thermal Oil Boilers Transfer Heat?

Thermal oil boilers transfer heat by burning fuel in the burner to produce high-temperature flames and flue gases, which flow through the furnace body and heat the thermal oil in the pipes. The thermal oil absorbs the heat and is pumped to the equipment or system that needs heating. Through heat exchangers or direct contact, the thermal oil transfers heat to the process medium or product, raising its temperature. The cooled thermal oil returns to the boiler to be reheated, continuing the cycle and achieving efficient heat transfer. This method allows thermal oil boilers to provide high-temperature heating at low pressure, with high energy utilization, stable operation, and safety, making them suitable for various industrial heating needs.

3.?Applications of Thermal Oil Boilers in the Pharmaceutical Industry

Thermal oil boilers, with their excellent heat transfer performance and versatile application scenarios, have become the preferred choice for many manufacturing enterprises.
