We are producing various types of Hot Oil Boiler with various capacities ranging from 100,000 to 5,000,000 kcal / h with Diesel, Fuel-oil, Natural Gas, LPG, Coal and Pellet Burning or Electrical energy.
DESIGN: Hot oil boiler, in accordance with DIN 4754, TS EN 12953 Loyd rules, TRD, DIN and EN norms, in a horizontal or vertical construction so that there is no stagnant point in turbulent flow, spiral-shaped, tubular-tube-shaped or bundled tube bundles, It is designed and manufactured.
MATERIALS:Our hot oil boilers are manufactured from P265GH or P295GH boiler plate according to EN 10028, serpantine pipes are produced with minimum 3.6 mm wall thickness of P235GH or P265GH according to EN 10216 or EN10217.
HIGH EFFICIENCY:3-currents of our hot oil boilers, after the combustion of the flame and smoke gases formed as a result of a good combustion on the heating surface is ensured after maximum heat transfer; The smoke gases are transferred to the chimney without creating low temperature corrosion. Thus, high boiler efficiency is obtained.
HOT OIL BOILER OPERATING PRINCIPLE:Thermal oil in the lubrication, at constant speeds of 1.5-2 m / s, passes through the pipes designed in a horizontal or vertical construction so that there is no stagnation point in the turbulent flow. the desired temperature range and hot oil is obtained at the desired temperature.
Advantages
•At atmospheric pressure up to 350 ° C.Thermal oil used as heat transfer in the system, does not leave deposits in the installation, does not make the stone, prevents the formation of corrosion.
•No conditioning is required for thermal oil.
•It does not freeze in winter in normal climatic conditions.
•The desired temperature can be set up to 350 ° C. (Specific equipment is used after 300 ° C.)
•In addition to being used at high temperatures, hot oil can be used in steam, hot water and hot water production if required.

What is Hot Oil Boiler? When to use Hot Oil Boiler?
On one side of the surface of the thermal oil as thermal field fluid, on the other side, there are roads in which a flame-smoke gas flows, closed pressure vessels are called hot oil boiler.
In industrial processes requiring high temperatures (max 350 ° C); steam or hot water can be used as heat transporters to reach these temperatures, but high temperatures such as 350 ° C can be reached at a pressure of 170 barg.
As the first installation costs of the plants operating at very high pressures are high, the maintenance costs of these facilities are also high: also the risk of explosion increases.
Use of thermal oils as atmospheric pressure at atmospheric pressure up to 350/400 ° C; as it has eliminated the above drawbacks; it also brings great advantages.

Advantages of Hot Oil Systems According to Other Heat Systems;
* At atmospheric pressure up to 350 °C. (The system only has a pressure created by the lubrication pump, which does not exceed max 5 bar,
* Thermal oil does not cause corrosion in installation and boiler coil, * In boiler; there are no problems such as boiler stone, calcification, * No treatment (conditioning) is applied to the thermal oil, * Under normal climatic conditions, installation will not freeze, * There is a wide range of settings up to 350 °C. However, in case of higher temperatures in the boilers, you can never exceed the operating pressure.
* Hot water, boiling water, steam can be produced by indirect oil (if necessary).
Disadvantages of Hot Oil Systems According to Other Heat Systems;
* Thermal oil to be filled into the system, the cost is high,
* There is a possibility of fire in case of any puncture or oil leakage in the boiler, (Thermal oil is a flammable substance.)
* Thermal oil in the system undergoes "cracking" at high temperatures and loses its natural properties. The bitumen (bitumen) parts adhere to the heating surfaces and reduce the heat transfer properties. In time, they can endanger the boiler,
* As the temperature of the thermal oil increases, it contacts with oxygen (air) to oxidize and begin to lose its natural properties and after a short time a sediment layer is formed on the heating surfaces,
* In time, the oil may need to be replaced when the thermal oil begins to lose its natural properties,
* The heat transfer capacity of thermal oil is not as high as water. During the heating, such as water, natural circulation is not easy. In this regard, forced oil circulation boilers are forced to circulate. There should be no stagnant point in the thermal oil in the boiler and a turbulent flow must be formed. The thermal oil velocity in the boiler is around 1.5 - 5 m / sec,
* Although there is no pressure in the hot oil systems, the luminaires used (valve, check valve, safety valve etc.) must be cast of PN40 class steel; the circulation pumps must also be cast steel,

CORRECT AND EFFICIENT TRANSMISSION OF HOT OIL;
POINTS TO BE CONSIDERED IN THE CONSTRUCTION OF THE HOT OIL SYSTEM
1. Thermal Oil Expansion Tank;
The total thermal oil in the installation (including the boiler) must be at least 30% of the volume.
The diameter of the expansion tank should be as small as possible (with little contact with the atmosphere) and the tank should be placed in a vertical cylinder.
2. Reserved Thermal Oil Tank; Least; It should be 1.5 times the whole thermal volume in the installation.
3. Thermal Oil Circulation Pumps; It should be specially designed for high temperature, preferably air cooled, steel cast or spherical cast iron.
4. Thermal Oil Filling Pumps; Gear pump designed according to the viscosity of thermal oil at room temperature can be used.
5. Valves, Check Valves, 3-Way Valves; Resistant to the operating temperature of the thermal oil; Copper or copper alloys should not be used, Valves should be cast in PN25 / 40 steel.
6. Filters;
In the installation, they contain the solids that are carried with the oil. It should be cleaned from time to time.
Keeping the filter surface as large as possible is appropriate for reducing the frequency of cleaning.
In order to determine the resistance caused by the contamination of the filter, a manometer should be placed at the inlet and outlet of the filter.
7. Thermal Oil Level Indicator; The temperature of the thermal oil in the expansion tank must be in accordance with its characteristics.
8. Piping and Fittings;
All pipe fittings must be steel. The use of non-alloy steels at 350 ° C is permitted. Carbonated (eg ASTMA-53) and ASTM A-106 or Std. 35.8 Seamless steel pipe can be used.
Cast iron can never be used (due to the risk of cracking, cracking, oil leaking). In addition, the pipe installation should be properly inclined and an air discharge pipe and valve should be installed where air collecting is possible.
The pipes that the oil circulates must be insulated with a thick enough thickness.
9. instruments; For safety and control, the hot oil system must have the following instruments,
a. Burner control thermostat b. Maximum temperature thermostat c. Differential prosestate or flow switch disables the burners when the oil circulation slows down or the oil lubrication pump is deactivated. d. Expansion tank minimum oil level lock: Stops the burner, triggers the alarm.
e. Chimney thermostat; When oil circulation stops for any reason; Since the flue gas temperature rises, the burner is automatically switched off.
