High temperatures are needed in various production processes taking place today. Therefore, the existence of a heat transfer environment that can meet this need is essential. In order to safely carry out operations requiring high temperatures, hot oil boilers are the appropriate option. Closed pressure, which contains thermal oil on one side of the hot oil boiler surface and heat-giving gases formed by burning the fuel on the other side. is the container. It has fully automatic control. It has high efficiency and is environmentally friendly.
What is the Working Principle of a Hot Oil Boiler?
The working principle of this type of oil boilers is based on heating the oil by superheating it. Thermal oil passes continuously through pipes built in a horizontal or vertical structure at a speed of approximately 2 m/s. During this, the thermal oil is heated to the desired temperature with the heat energy received from the gases formed 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 burned when there is no fuel inside and it should be ensured that the chimney draft is sufficient. Because poor traction both reduces the efficiency of the boiler and poses a threat to human health. Of course, daily, monthly and annual maintenance operations should not be interrupted.
What are its Usage Areas?
These products are used in processes that require high temperatures, such as cooking and drying, in facilities such as woodworking, chemical industry, food industry, textile and automotive, and in the production of products such as paper and rubber. It is especially suitable for use in low pressure businesses.
Which are the Hot Oil Boiler Models?
This type of boilers are divided into different types. The models that can be used may vary depending on the material to be used. Liquid and gas fuel models work with natural gas. In the rotary grill combustion system model, when coal is poured into the grill, it advances with the rotation speed of the grill. 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 has a grate. Thanks to this, the product model can operate proportionally according to the heat need.
Oil and Gas Fuel Hot Oil Boilers
As the name suggests, liquid and gas fueled hot oil boiler models are used with gas and liquid fuel. It is used in situations where high temperature levels are desired at low pressure levels. Boilers insulated against heat losses minimize heat loss.
Rotary Grate Hot 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. Rotary grate hot oil boiler is known as one of the most efficient boilers. A very small amount of slag is produced after combustion in the boiler, where the entire process is automated.
Fluidized Bed Hot Oil Boilers
Fluidized bed hot oil boilers are boilers designed to burn solid fuel. Being environmentally friendly and highly efficient are among the reasons why these boilers are frequently preferred. In this boiler, combustion takes place on a bed that is a mixture of ash and coal.
Forward Thrust Hot Oil Boilers
Forward thrust hot oil boilers, which can be used with solid and liquid fuel, have the ability to operate proportionally, fully meeting the heat need. Thus, different heat needs can be met with high efficiency. The gases resulting from combustion are discharged through the chimney within the values allowed 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 and 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 its disadvantages. Thermal oil in the boiler is a flammable substance. Therefore, there is a risk of fire in case of a puncture or oil leak 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 phenomenon, called cracking, the heat transfer feature of the boiler decreases.
Hot Oil Boiler Prices
Hot oil boiler pricesmay vary depending on the model. Prices of imported models may be slightly higher. The features of the burner and pump used with the boiler may also increase or decrease its price. One of the factors that determine the cost is kcal/hour capacity.
