Nowadays, many heaters have energy-saving features, and air heaters are no exception. However, few people know the specific design aspects that make air heaters energy-efficient. Now, let me explain the energy-saving design of air heaters from three aspects.
1. Reasonably design air volume and temperature rise. The power of the air heater is calculated based on air volume and temperature rise. Under the premise that air volume and temperature rise meet the requirements, it is not advisable to use excessive air volume or temperature rise, as they will directly lead to higher power consumption and increased energy consumption. Excessive air volume and temperature rise are unnecessary. Comprehensive consideration and reasonable design are needed to determine appropriate parameters.
2. Add insulation layer on the surface of the air heater. Only insulate the pipeline at the outlet of the electric heater, without any insulation treatment on the surface of the electric heater itself. Comparative data show that adding an insulation layer on the surface of the electric heater can reduce energy consumption by 5% to 10%. Over long-term operation, the energy savings are considerable. Power plants (owners) should add insulation layers to the air heater while insulating the pipelines.
3. Reduce the pressure loss of the air heater itself. The air to be heated generates pressure loss when flowing through the interior of the air heater. The greater the pressure loss, the higher the energy consumption of the fan. Improvements and innovations should be made to the structure of the air heater itself to minimize the pressure loss.
