Energy-saving design of air heater

Reasonable to design the air volume and temperature rise. The power of the air heater is determined according to the air volume and the temperature rise. Under the premise that the air volume and temperature rise have met the requirements, it is not suitable to use excessive air volume and excessive temperature rise due to excessive air volume and temperature rise. Directly will cause the heater's power to be too large, increasing energy consumption. Excessive air volume and temperature rise are not necessary. To comprehensive consideration, rational design, determine the appropriate parameters.

The pressure loss of the air heater itself is reduced. The air to be heated flows through the interior of the air heater to cause pressure loss. The greater the pressure loss, the greater the energy consumption of the fan. The structure of the air heater itself should be improved and innovated to minimize the pressure loss.

On the surface of the air heater, an insulation layer should be added. Only the pipe of the electric heater outlet is insulated, and the surface of the electric heater itself is not insulated. The comparison data shows that the addition of insulation layer on the surface of the electric heater can reduce the energy consumption by 5%~10%. The long-term operation and the energy consumption saved are considerable. The power plant (owner) should install the insulation layer on the pipeline. Then, add an insulation layer to the air heater.
