Energy saving performance and application range of air electric heater

The air heater is the electric heating equipment which mainly heat the gas flow. The heating element of the air heater is the stainless steel electric heating tube. There are many baffles (deflector) in the inner cavity of the heater, which guides the gas flow direction and prolongs the gas residence time in the inner cavity, so that the gas is fully heated, so that the gas is heated uniformly, and the heat exchange efficiency is improved. Heating element: stainless steel tube air heater, electric heating wire is loaded in the seamless steel pipe, the void is filled with good heat conductivity and insulation of magnesium oxide powder after a pipe. When the current through the high temperature resistance wire, the surface of the heat pipe diffusion through the heating crystallization of magnesia powder, and then pass to the heated air, to achieve the purpose of heating.

In the absence of any such measures, the use of natural air electric heater cannot reflect the energy and side, to achieve the goal of energy conservation, can start from the improvement of electric heater structure, adjust its parameters and so on, believe that after the change of the effect is obviously.

A large part of the users are using the air electric heater when they only heat the outlet of the electric heater, but do not keep any heat treatment on the surface of the electric heater itself. However, it has been proved that increasing the thermal insulation layer on the surface of the air electric heater can reduce a lot of energy consumption.

So remind the users of the air electric heater, while installing the insulation layer on the equipment pipe, do not forget to install the insulation layer on the air electric heater itself. This long-term operation, the energy saving is very considerable, can reduce the operation cost of the equipment.

The power of the general air electric heater is calculated based on the air volume and temperature rise. Therefore, if the air volume and temperature rise have already met the needs, it is not suitable to use excessive air volume and excessive temperature rise. Otherwise, it will directly lead to too much power and increase energy consumption of heater. Therefore, it is crucial to design reasonable and determine the appropriate parameters.

When the air that needs heating flows through the air electric heater, the pressure loss is generated, and the greater the pressure loss, the greater the energy consumption of the fan. Therefore, it should be improved from the structure of the air electric heater itself, so as to reduce the pressure loss as much as possible, which is beneficial to the realization of energy saving.

The application range of heater, air heater is a widely used heater. We popularly call it air heater. Actually, it can be divided into many kinds according to the difference of heating gas. There are many kinds of nitrogen heater and hydrogen heater. These can also be called pipe gas heaters. It has been widely used in many research and production laboratories, such as aeronautics and Astronautics, weapons industry, chemical industry and colleges and universities. It is especially suitable for automatic temperature control and high flow high temperature combined system and accessories test. The range of air electric heater is wide: it can heat any gas and generate hot air, no water, no electricity, no burning, no explosion, no chemical corrosion, no pollution, safe and reliable, and the heating space will be heated up quickly (controllable).
