Reasons for insufficient heating capacity of finned tube heat exchanger
① The pressure or temperature at the hot side of the pipe is too low, and the main symptom is that the temperature of the hot air at the cold side is close to the temperature at the hot side.
② The flow in the hot side of the pipe is too low, and the main symptom is that the temperature difference between the inlet and outlet of the hot side is large.
③ The flow distribution of several finned tube heat exchangers operating in parallel is uneven. The main symptom is that the inlet and outlet temperatures of each heat exchanger are inconsistent.
④ The heat transfer performance of finned tube radiator decreases with the service time.
⑤ The design effect was not achieved during the installation and commissioning of finned tube radiator, and the pipeline stroke was connected correctly, and the thermal insulation measures were ideal.
