What Is the Thermal Oil Heater Working Principle?

Our thermal oil heater consists of different parts that make the whole process happen and work efficiently. The helical coil is the main part of every thermal oil heater that gets heated and produces energy by the combustion of fuel.

The high temperature oil recycles pumps forced to run oil or liquid fuel that is being used in the process, and the helical coil heats that thermal oil. The best thing is that: It is not a pressurized system as water or steam boiler systems.

Thermal oil heater working principle

In every thermal oil heater system, these fluids are used to transfer heat. And these fluids are then circulated as wood, oil, or gas, electric heaters. This heat transfer fuel is then directly contacted with the heater element and then pumped into the system to the process heat users.

After that, it also goes back to the heating unit. So, it makes a loop process that starts from one point and ends at the same point.

The Hot oil heater carries a continuous system, and the plants of the thermal oil heater boiler work with no break.

What Is the Thermal Oil Heater Price?

The most significant concern of every buyer is the thermal oil heater price, so we are sharing an overview of market prices at which an efficient thermal oil boiler is available in the market.

Before buying an oil boiler, you must understand that the thermal oil heater price depends on different factors, as given below:

Thermal Oil Heater Capacity:

The first thing on which a thermal oil heater price depends is the capacity of the machine. The manufacturers of thermal oil heater design systems for different capacities as per industry needs. Heat capacity is different for different materials, so you will have first to decide the fuel that you want to use as a heat transfer and then calculate the capacity of the heat required to boil that fuel.

You can get thermal heaters with a capacity of 200kw-14000kw; 100000kcal-12000000kcal and even greater than this. So, before buying it, make sure that you know the capacity so that you can find the right capacity for your industry.

Thermak Oil Boiler Fuel Used:

Now, let’s discuss another significant factor that affects the price of the boiler. Different thermal oil heater systems are available in the market, and one thermal oil heater system can offer you different fuel options.

Therefore, if you invest in an excellent thermal oil heater system, it can give you the freedom to choose different heat transfer fuels like sawdust, coal, oil, gas, diesel, biomass, wood and husk, etc.

These are some factors that will affect the price of your thermal oil heater system. So, be sure about what you are buying so that you can pay for the right product.

What Are The Boots Of Your Thermal Oil Heater System?

You may get shocked to hear that a thermal oil heater system is far better than a steam boiler or water boiler. Now, you must be thinking about how that is even possible, so here we are with some valid reasons that make a thermal oil heater system better than a water boiler. So, let’s have a look!

1. Yongxing thermal oil heater adopts an advanced control system to control the medium, with high thermal efficiency and convenient maintenance. A thermal oil heater system gives better control for temperature as compared to water or steam boilers.

These systems offer outstanding reliability that a hot water boiler or steam boiler fails to deliver. In addition, these thermal oil heaters have simple and rugged designs. Also, if you invest in a good and efficient system, its longevity will keep you safe from maintenance or replacement after a few years. A thermal oil heater system can go a long way!

2. Because there is no need for excessive auxiliary equipment, our thermal oil heater is compact in structure, saving you more floor space.

3. We design integrates automatic detection, control, and chain alarm prompts. Nobody needs to be on duty when you buy it, which can significantly save your factory’s human resources.

4. The size matches the burning flame, and the radiation heat transfer rate is high.

5. The thermal oil heater adopts a three-pass round coil structure, with a large heating surface and high thermal efficiency.

6. Under normal circumstances, we will install an air preheater at the end of the thermal oil heater, which dramatically improves the boiler’s efficiency.

7. The thermal oil heating system’s heat supply can be as high as 320~350℃, and the working pressure is below 1MPa.

8. The diameter and length of the radiant coil are compatible with the burner’s flame, to ensure the regular operation and sufficient cooling of the thermal oil heater coil.

We use professional boiler materials to ensure the high-quality completion of each boiler. Besides, we make a profit to customers and provide the lowest thermal oil heater price to meet your various needs.

Except oil gas fired thermal oil heater, Yongxing also supplies the coal fired thermal oil heater.

9. Oils have greater boiling points as compared to water, so thermal oil heater systems have higher temperature ranges that make them perfect for various industries.

Water or steam causes corrosion inside the system, which badly affects the working and efficiency of the system. In a thermal oil heater machine or system, no water is used on the flip card, which makes it safe from corrosion.

In a water boiler, you need a lubricant to keep the parts of the boilers safe from friction and ensure smooth working.

On the other hand, a thermal oil heater system is a self-lubricating system that needs no lubrication. In this way, the thermal oil heater system cuts the thermal oil heater price.

10. Another most significant advantage of a thermal oil heater is that it can maintain a high temperature for a longer duration and can operate at low pressures at the same time.

In this way, this system is much safer for the people working near it as compared to water or steam boilers, which operate at higher pressures.

How To Clean the Thermal Oil Heater Boiler?

For some users, cleaning is difficult when it comes to thermal oil heaters and raises significant concerns, because of course, if your boiler isn’t maintained correctly, it will affect the quality of the product it delivers.

It is impossible for a human to clean a thermal oil heater or boiler. If you invest in a good quality thermal oil heater, it will have an automatic cleaning system that will clean out all the deposits from the convection boiler of the heater.

However, you must know that the level of contamination also affects the operating frequency and the deployment of the system. There is a fan placed behind the convection boiler, and it sucks the flue gas.

What Is a Coal-Fired Thermal Oil Heater?

Coal-fired thermal oil heater is just a simple thermal oil heater system that uses coal as a fuel for the heating process. A thermal oil heater could accept different fuels as heat transfer elements. The systems that use coal as a fuel are called coal-fired thermal oil heaters.

There can be some differences in the specifications in a coal-fired thermal oil heater as compared to another fuel type depending on the fuel density and nature.

But the main system of the thermal oil heater which is coal-fired is the same as that of other fuel thermal oil heater systems.
