Paper Mill Primary And Secondary Heaters

Paper Mill Primary and Secondary Heaters

Finned tube heat exchanger is a common heat transfer equipment, widely used in primary and secondary heaters in paper mills. It increases the heat transfer area and improves the heat transfer efficiency by adding fins on the surface of the heat transfer tube.

In the production process of paper mills, pulp needs to be heated and dried to improve the quality of paper and production efficiency. The finned tube heat exchanger can transfer heat from a heat source such as steam or thermal oil to the pulp to achieve the required temperature and humidity.

The advantages of finned tube heat exchangers include:

High heat transfer efficiency: The fins of the finned tube heat exchanger increase the heat transfer area, which improves the heat transfer efficiency and enables rapid heat transfer to the pulp.

Compact structure: the finned tube heat exchanger has a compact structure, takes up little space and is easy to install and maintain.

Strong adaptability: finned tube heat exchanger can be designed and manufactured according to different process requirements and heat source conditions, strong adaptability.

Convenient maintenance: finned tube heat exchanger has simple structure, convenient maintenance and long service life.

When choosing finned tube heat exchanger, the following factors need to be considered:

Heat exchange area: According to the process requirements and heat source conditions, select the appropriate heat exchange area to ensure that the heat exchanger can meet the production requirements.

Material: According to the nature of the medium and the working conditions, select the appropriate material to ensure that the heat exchanger corrosion resistance and high temperature resistance.

Pressure loss: When selecting finned tube heat exchanger, pressure loss needs to be considered to ensure the operational efficiency and stability of the heat exchanger.

Maintenance cost: When choosing finned tube heat exchanger, you need to consider the maintenance cost and choose the heat exchanger that is easy to maintain and replace.
