The exterior of the air electric heater should be insulated with a layer of insulation
In recent years, with the demand for desulfurization projects in large power plant units, the power of air electric heaters has been increased, some of which can reach over 400KW. Electricity consumption is high and operating costs are high. It is necessary to consider the following aspects and try to reduce power as much as possible.
(1) Reasonably describe the air volume and temperature rise. The power of an air electric heater is determined based on the calculation of air volume and temperature rise. On the premise that the air volume and temperature rise meet the requirements, it is not advisable to choose a too large air volume and temperature rise, as excessive air volume and temperature rise directly lead to excessive power of the heater and additional energy consumption. Excessive air volume and temperature rise are unnecessary. To summarize and think, describe reasonably, and determine appropriate parameters.
(2) The exterior of the air electric heater should be insulated. Most power plants (owners) only insulate the pipes at the outlet of the air electric heater when using it, without any insulation treatment on the surface of the electric heater itself. According to the data, adding insulation layer on the surface of the electric heater can reduce energy consumption by 5% to 10%. If the energy consumption savings are significant after long-term operation, the power plant (owner) should install insulation layer on the air electric heater along with the pipeline.
(3) The pressure of the descending air electric heater itself is lost. When the air that needs to be heated flows through the interior of the air electric heater, pressure loss occurs. The greater the pressure loss, the greater the energy consumption of the fan. Improvement and innovation should be made in the layout of the air electric heater itself to minimize the pressure loss.
