High temperatures are needed in various production processes taking place today. Therefore, the presence of a heat transfer medium that can meet this need is essential. Thermal oil boilers are a suitable option to safely perform processes that require high temperatures . The hot oil boiler is a closed pressure vessel with thermal oil on one side of the surface and the pathways containing the heat-giving gases formed by burning the fuel on the other side. It has fully automatic control. It has high efficiency and is environmentally friendly.
What is the Working Principle of Thermal Oil Boiler?
The working principle of such oil boilers is based on heating the oil by superheating. The thermal oil passes continuously at a speed of about 2 m/s through horizontally or vertically constructed pipes. During this, the thermal oil is heated to the desired temperature with the heat energy taken from the gases generated in the combustion chamber.
How to Use?
First of all, the boiler should be placed on a flat and concrete floor. It should never be lit when there is no fuel inside and make sure that the chimney draft is sufficient. Because bad traction both reduces the efficiency of the boiler and poses a threat to human health. Of course, daily, monthly and annual maintenance should not be disrupted.
What are the Areas of Use?
These products are used in facilities such as wood, chemical industry, food industry, textile and automotive, in the production of products such as paper and rubber, in processes where high temperature is required such as cooking and drying. It is especially suitable for use in low pressure enterprises.
What are the Hot Oil Boiler Models?
This type of boilers are divided into varieties among themselves. The models that can be used may vary according to the material to be placed inside. Liquid and gas fuel model works with natural gas. In the model with rotary grate combustion system, when coal is poured into the grate, it progresses with the rotation speed of the grate. The fluidized bed model is an option suitable for burning solid oil and has a water pipe. The forward thrust model is also used in solid fuel systems, the combustion system is grate. Thanks to this, the product model can operate proportionally according to the heat requirement.
Liquid and Gas Fired Thermal Oil Boilers
As the name suggests, liquid and gas fired hot oil boiler models are used with gas and liquid fuel. It is used in cases where high temperature level is desired to be reached at low pressure level. The boilers, which are insulated against heat losses, minimize heat loss.
Rotary Grate Thermal Oil Boilers
In this system, the coal added to the boiler rotates after entering the boiler and continues to burn with all its components until the end of the process. The rotary grate hot oil boiler is known as one of the most efficient boilers. In the boiler where the whole process is automated, a very small amount of slag is produced after combustion.
Fluidized Bed Thermal Oil Boilers
Fluidized bed thermal oil boilers are boilers designed to burn solid fuel. Environmentally friendly and highly efficient are among the reasons why these boilers are frequently preferred. In this boiler, combustion takes place over a bed which is a mixture of ash and coal.
Advanced Thermal Oil Boilers
Advanced propulsion hot oil boilers, which can be used with solid and liquid fuels, have the ability to operate proportionally to fully meet the heat requirement. Thus, different heat needs can be met with high efficiency. The gases produced as a result of combustion are discharged from the chimney within the values permitted by the regulation.
What are the Advantages and Disadvantages?
First of all, it facilitates production in various sectors. There is no calcification problem in the boiler. The temperature can be controlled better, it can be operated at higher temperatures than water boilers. Maintenance and operation are not costly. However, while talking about these advantages, it is also necessary to mention the disadvantages. Thermal oil in the boiler is a flammable substance. Therefore, there is a fire hazard in case of a puncture or oil leakage in the boiler. However, as the boiler is used at high temperatures for a long time, it loses its natural structure. As a result of this event called cracking, the heat transfer feature of the boiler decreases.
Hot Oil Boiler Prices
Hot oil boiler prices may vary according to their models. Prices of imported models may be slightly higher. The features of the burner and pump used with the boiler can also increase or decrease the price. One of the factors determining the cost is the kcal/hour capacity.
