Air Heater

Description: air heater is mainly for heating the gas stream of electric heating equipment. The heating elements of stainless steel air heater electric heating tube heater cavity with a plurality of baffles (baffles), direct gas flow, extend the residence time of the gas, so that gas is sufficiently heated, the gas is heated evenly, increase the heat exchange efficiency. After the heating element stainless steel air heater heating pipes, electric wires is charged in the seamless steel tubes, voids partially filled oil good thermal conductivity and insulation made of magnesium oxide powder shrink tube. When the current through the high temperature resistance wire when the diffusion heat generated by crystallization of magnesium oxide powder to the heating surface of the tube to be passed to the heated air in order to achieve the purpose of heating the product: The operating principle is to a large number of turns The primary coil and a secondary coil mounted turns less on the same core. Input and output voltage ratio is equal to the ratio of the windings, while the energy remains the same. Thus, a large current at a low voltage secondary winding conditions. For induction heater, the bearing is a single-turn secondary winding shorted, at a lower AC voltage flows at high amperage, thus generating high heat. The heater itself remains at ambient temperature and the yoke. Since this heating method can induce a current, the bearing will become magnetized. It is important to ensure that the bearing is degaussing, so that in the course of their work will not attract metal magnetic shavings, FAG induction heaters have automatic degaussing function. Is the use of metal in an alternating magnetic field vortex leaving the heat itself, it is often used in metal heat treatment and so on. The principle is the alternating magnetic field will be generated by the electromagnetic induction current in thick metal. And after thick metal which generates an electrical current in the metal formed inside the spiral flow path, so the heat generated due to the current flow was absorbed by the metal itself, and will cause the metal to heat up quickly. In the high temperature stainless steel seamless pipe evenly distributed temperature resistance wire, in a space portion densely populated thermal conductivity and insulation properties are good crystalline magnesium oxide, this structure is not only advanced, high thermal efficiency and even heating when temperature resistance wire The heat generated when the current through the crystalline magnesium oxide powder to diffuse through the surface of the metal pipe, and then transmitted to the member or object to be heated in air to achieve heating. Air heater is mainly used to require air flow from the initial temperature of the heating to the desired space temperature, up to 850 ℃, has been widely applied to aerospace, weapons industry, chemical industry and universities and other Many research and production laboratories. Especially suitable for automatic temperature control and high temperatures combined with high flow test systems and accessories. Electric air heaters use a wide range: can be heated to any gas, hot air generated by dry and free of moisture, non-conductive, non-burning, non-explosive, non-corrosive, non-polluting, safe, reliable, space heating is heating up fast (available control). Features: 1, air can be heated to a high temperature, up to 450 ℃, the shell temperature is only about 50 ℃. 2, high efficiency, up to 0.9. 3, heating and cooling speed, up to 10 ℃ / S, adjust fast and stable and will not appear under the control of temperature and hysteresis lead leaving the temperature control drifting, it is suitable for automatic control. 4, good mechanical properties: it is the characteristics of the heating element alloy, so the impact of high pressure in the air flow, it is better than any mechanical performance and strength of the heating element, which takes a long time for continuous air heating Test systems and accessories has more advantages. 5, using the rules violation, durable, long service life for decades. 6, the air clean, small size. Categories: air heater is to use very widely used as a heater, we commonly call buffeting air heaters, in fact, according to the heated gas can be divided into many categories, a common nitrogen heater, hydrogen heater, line heaters, water heaters and other pipes. Application: 1, the chemical industry, chemical materials heating heating, under pressure of some powder dry, chemical process, and spray drying. 2, hydrocarbons heating, including crude oil, heavy oil, fuel oil, oil, oil, paraffin. 3, industrial water, superheated steam, molten salts, nitrogen (air) gas, water gas category, and so need to heat up the heated fluid heating. 4, due to the use of advanced explosion-proof structure, equipment widely used in the chemical industry, military, petroleum, natural gas, offshore platforms, ships, mining and other needs of the explosion sites.
