Thermal Fluid Boilers Detailed FAQ Guide
Do you need a permanent solution for eliminating overpressure issues? Introducing the thermal fluid boilers, which offer significantly higher temperature range at low pressures. As these thermal boiler systems dominate China’s industrial zone, the Yongxing engineers have decided to develop a better design.
With the help of experienced engineers, we have designed thermal fluid heaters which offer more control, flexibility, and reliability. Wondering how these thermal fluid boilers work? Here is a detailed FAQ guide that includes the introduction to the working process of our hot oil heaters.
What Is A Thermal Fluid Boiler?
The thermal fluid heaters have a close loop design of vertical and horizontal coils. Inside these coils, a thermal fluid is in constant circulation that provides heat through convection and radiation. The heat transfer is at a constant temperature and fully controlled by the user with the help of secondary control loops.
The fuel burns inside the combustion chamber and thus produces heat. Afterward, the thermal fluid absorbs the heat from the chamber and flows out of the furnace. These systems have an advantage over steam boiler and hot water boilers because it provides heat at very low pressure.
You may find the thermal fluid boilers by different names. However, they all are the same closed-loop designs. Following are some of the names of these oil-based systems.
- Thermal oil heater
- Thermal boiler system
- Thermal oil heating system
- Thermal fluid heater
- Hot oil heater
- Thermal oil system
The thermal fluid boilers operate using different types of heat transfer fluids. In order to know the one that suits your facility, you must understand the application of these fluids. Here are the fluid options and their application.
Types Of Thermal Fluids
There are three types of heat transfer fluids used in thermal fluid heaters:
- Hot Water
- Water Glycol Solutions
- Thermal Oil
Let’s have a brief discussion on each one of them.
Water is the best choice when used as a heat transfer medium, especially in view of its thermophysical properties. It has the best heat transferring abilities; however, it must be used with extra caution. If the water used is not free of contaminants, it will cause corrosive damage to the coils of thermal fluid boilers.
So, you will need a water treatment plant if you are using water as a heat transfer medium. Furthermore, the water has low boiling and high freezing point. It means that your heat transfer medium is vulnerable, and you won’t get high efficiency using it. What’s the best alternative for it? The water-glycol solution.
Since the water has high freezing and low boiling points, you can use the water-glycol mixture to solve this problem. When you mix water and glycol, you increase the waters’ boiling point and decrease its freezing point. As a result, it will increase your thermal fluid heaters’ efficiency. But while using the water-glycol solution, you are compromising on fluids’ heat capacity.
Thermal oils are the best heat transfer medium for thermal fluid boilers. As compared to water solutions, it can bear high temperatures without boiling and excessively increasing the system’s pressure. The natural oils can bear temperatures up to 315, while some synthetic oils can reach 427.
In addition to high temperature bearing ability, thermal oils fulfill ASME VIII conditions. It means that you won’t need a permit to use a thermal fluid boiler in your facility. Plus, the thermal oils don’t need a treatment plant and won’t do corrosive damage to your systems. For these reasons, the Yongxing thermaic fluid heaters use thermal oils as a heat transfer medium.
What Is Your Thermal Fluid Boiler System Design?
The Yongxing thermal fluid boilers have a unique fired heating system. It has special pumps that transfer the fluid to the fired heating system to raise its temperature. In the heating system, thermal oils are used for providing heat to the fluid of the system.
The overall thermal fluid boilers depend on the proper function of five major components. Here are their details and how they are designed to enhance efficiency.
Five Major Components Of Thermal Fluid Boilers
- Control panels
- Expansion tank
The valves are used to control the fluid flow of the thermal fluid boilers system. Therefore, the Yongxing engineers have designed sturdy and leak-free valves to achieve high efficiency. It has improved control over the fluid flow without any leakage risk. In addition, the valves come with a bellow-type seal that completely closes when in contact with surfaces. These valves have the tendency to resist wear for a longer period and are designed with forged carbon steel.
The pump is the component that is used to transfer the fluid throughout the thermal oil system. It is a device through which the thermal fluid boilers control fluid velocity, flow direction, and the system’s overall pressure.
The Yongxing thermal fluid boilers pumps are no ordinary pumps; they are specially designed for these systems. You get a specific pump size that is designed as per the thermal fluid gravity at operational temperatures and pressure loss. Plus, these pumps come with high-quality mechanical seals. So, there are no chances of pressure and liquid leakage.
The furnace is a chamber in a thermal boiler system where the fuel burns and produces heat. Prior to pumping, the furnace heats the thermal oil, and then it’s pumped to the overall system. The furnace chamber size varies as per the different models of Yongxing thermal fluid boilers.
The chambers’ size changes as per the heat load and thermal fluid. For maintaining the power demands, each type of thermal oil heater comes with a different chamber size that successfully fulfills the power demands. And for minimizing the radiation, the furnace is well covered with a thick shielded material layer.
If you want to know the technical parameters of Yongxing thermal fluid boilers, you can check them at our website’s specific boilers catalog. Also, you can contact our 24/7 active customer support for any of your queries.
The Yongxing thermal fluid boiler’s automation is dependent on these control panels. These PLCs (Programmable Logistic Controllers) ensure that you get full operation monitoring. Moreover, it will tell you of any mishap in the boilers’ performance using UV scanners and pressure monitoring circuits.
These PLC packages integrated with the thermal fluid boilers’ heaters help you monitor the fluid flow using the differential pressure switches and orifice plate. And using these control panels, you get warning signals for pressure overload, the system heats up, over the expansion of tank, automatic interlocks, etc.
The Yongxing thermal oil heaters offer a unique thermal expansion reservoir. It is perfectly designed to store thermal oil for minimizing shutdowns. And it has the ability to absorb all thermal expansions from the oil pump. However, since the pumps move the thermal oil throughout the system, you must check them time-to-time to avoid system breakdowns.

How Do Your Thermal Fluid Boilers Work?
The thermal fluid boilers’ fame is getting more and more every day, and for a good reason. The overall working principle is simple, and it produces high temperatures without over-pressuring. Here is the overall working principle.
Thermal Fluid Boilers’ Working Principle
When the fuel burns in the thermal fluid boilers’ furnace, it produces heat that is used for steam production. Inside the furnace, there is a coil in a round shape through which the thermal oil flows. Plus, there is an FD fan that supports the combustion by providing a constant air supply.
In addition, the Yongxing thermal fluid boilers have an oil storage tank and oil feeding pump useful for maintaining the continuous steam production process. The oil tank stores the thermal oil, and the oil feeding pump transfers the thermal oil from the storage tank to the coils.
It has a three-way coil design that helps reheat the thermal fluid. In the first pass, it absorbs heat and then flows through the second and third pass to absorb a large amount of heat. As a result, it will improve the thermal fluid boilers’ thermal efficiency and decrease the exhaust gases flue temperature.
For pushing high-temperature thermal oil, specially-engineered circulating pumps are installed in the thermal fluid boilers’ system. And while moving throughout the system, the thermal oil passes through the expansion tank.
When the thermal oil absorbs heat, it passes through the system and loses its heat, due to which it expands. Since you can’t allow the thermal oil to expand in the coils or furnace, our thermal fluid boilers come with an expansion tank that compensates for the oil’s expansion. After passing through the expansion tank, the thermal oil goes back to the furnace’s coil for reheating.
As for the exhaust gasses, our eco-friendly thermal fluid boilers have an ID fan that pushes them out of the thermal fluid boilers’ chimney section. And the dust collector collects the heavy particles in the exhaust gasses and allows just gas to pass through the boilers’ chimney.
