Pipeline electric heaters are widely used in industry and can heat air, nitrogen, water, oil and other media. In recent years, as the output power of pipeline electric heaters has increased, some have reached about 500KW. High power consumption and high operating cost. Pipeline electric heater manufacturers consider the following points and need to minimize energy consumption and reduce unnecessary losses.
(1) A reasonable description of air volume and temperature rise. The power of the electric air heater is determined based on the calculation of air volume and temperature rise. Under the premise of meeting the demand for air volume and temperature rise, excessive air volume and temperature should not be selected, but the power and energy consumption of the heater should be directly increased through excessive air volume and temperature. There is no need to increase the amount of air and temperature too much. Summarize ideas, describe them reasonably, and determine appropriate parameters.
(2) An insulation layer should be added to the outer surface of the pipeline electric heater. This can reduce the external diffusion of heat inside the electric heater, thereby effectively reducing unnecessary energy consumption. Many users only maintain the outlet pipe of the electric heater when using the electric heater, and do not maintain the appearance of the electric heater itself. In fact, it is wrong, the heater itself must be kept warm. The data shows that adding an insulation layer on the outer surface of the electric heater can reduce energy consumption by 5% to 10%. Long-term operation can save a lot of energy consumption. The user should add an insulation layer to the electric air heater, and add an insulation layer to the pipeline.
(3) Reduce the working pressure loss of the pipeline electric heater itself. When the air to be heated flows through the electric air heater, pressure loss occurs. The greater the pressure loss, the greater the energy consumption of the blower. The layout of the electric air heater should be improved and modified to minimize the pressure loss.
