Air heaters are widely used heaters

Air heaters are widely used.

Air heaters are electric heating devices that primarily heat gas flows. The heating element is a stainless steel electric heating tube. Multiple baffles (guide plates) are installed within the heater cavity to guide the gas flow and extend the gas's residence time within the cavity, ensuring sufficient and even heating of the gas and improving heat exchange efficiency. The stainless steel heating tube is a seamless steel tube containing a heating wire, with the open space filled with magnesium oxide powder, which has excellent thermal conductivity and insulation properties. When current passes through the high-temperature resistance wire, the heat generated diffuses through the crystallized magnesium oxide powder to the surface of the heating tube and then transfers to the heated air.

Air heaters are a widely used type of heater. While we generally refer to them as air heaters, they can be further categorized into various types depending on the gas being heated. Nitrogen heaters and hydrogen heaters are common. These are also known as ducted gas heaters. They are widely used in research and production laboratories in aerospace, weapons, chemical, and university settings.

Typical applications for explosion-proof fluid electric heaters include:

1. Applications in the chemical industry as air heaters for heating chemical materials, drying powders under pressure, chemical processes, and spray drying.

2. Heating hydrocarbons, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin, etc.

3. Heating process water, superheated steam, molten salt, nitrogen (air), water gas, and other fluids requiring heating.

4. Due to its advanced explosion-proof structure, the equipment can be widely used in chemical, military, oil, natural gas, offshore platforms, ships, mining areas, and other explosion-proof environments.
