What is a large air heater used for?

Large air heaters are generally used in industry, and are mostly used in the pre-heating of fuel oil such as heavy oil, asphalt, and clear oil.

1. Air heater is a very widely used heater, we call it air heater, in fact, it can be divided into many types according to the lack of heating gas, the common ones are nitrogen heaters, hydrogen heaters. These can also be referred to as pipeline gas heaters.

2. The working principle is to install a primary coil with more turns and a secondary coil with fewer turns on the same core. The voltage ratio of the input to the output is equal to the coil turns.

3. Electric heaters do not need any other auxiliary equipment, and have obvious advantages over other equipment such as small boilers in terms of installation, operation and maintenance.

4. After the heater is installed, it is integrated with the air conditioning unit and the air energy heat pump water heater, which can be controlled by linkage with the unit when used, pre-heating the circulating water and increasing the water temperature, which not only ensures the normal start and operation of the air conditioning unit, but also improves the heating efficiency and heating effect of the air conditioning unit.

5. The power consumption of the heater itself can be compensated by improving the efficiency of the heating operation of the air conditioning unit and the air energy heat pump unit, and the total power consumption does not increase much.

Air heater, as the name suggests, is a kind of machine and equipment that heats air. The air heater is actually similar to the air conditioner, but it is fundamentally different from the air conditioner, the air conditioner can both heat and cool, but the air heater only has the function of heating the air. The working principle of the air heater is actually very simple, it mainly uses some stainless steel electric heating pipes as heating elements, and guides the air to the electric heating pipes with the deflector plate inside, and then excludes the air after heating.

In this way, the effect of heating the air is achieved. The characteristics of air heating gas are that the air is heated very uniformly, and the heating efficiency is very high. Therefore, air heaters have been favored by people since their inception.

Through the air supply system, the gas entering the air heater is formed at high temperature and the gas is discharged at high pressure. The hot air produced is dry and water-free, non-static, non-conductive, non-combustible, non-electrochemically corrosive, non-polluting, safe and reliable. It is widely used in aerospace, weapons Changxiang industry, chemical industry, power station air conveying chute gasification air heating, electrostatic precipitator ash bucket gasification wind heating and ash storage gasification air heating.

Technical features: 1. It can make the air heated to a very high temperature, up to 450, and the shell temperature is only about 50.

2. High efficiency: up to above.

3. The heating and cooling rate block can reach 10 s, and the adjustment is fast and stable. There will be no temperature advance and lag phenomenon of controlled air shortage, which will make the temperature control drift, which is very resistant to automatic control.

4. Good mechanical properties: because its heating element is a special alloy material, it has better mechanical properties and strength than any heating element under the impact of high-pressure air flow, which is more advantageous for system and accessory tests that require long-term continuous heating of air.

5. When it does not violate the rules of use, it is durable and has a service life of up to several decades.

6. Clean air and small size.

A primary coil with a high number of turns and a secondary coil with a lower number of turns are mounted on the same core. The voltage ratio of the input to the output is equal to the ratio of the number of turns of the coil, while the energy remains the same. As a result, the secondary coil generates a large current at low voltage.

In the case of induction heaters, the bearing is a short-circuited, single-turn secondary coil that generates a large amount of heat by passing a high current at a lower AC voltage. The heater itself and the yoke are kept at room temperature.

Since this heating method induces an electric current, the bearing is magnetized. It is important to ensure that the bearings are degaussed later so that they do not attract metal chips during operation, and FAG induction heaters have automatic demagnetization capabilities.

It is the use of eddy currents generated by metals in alternating magnetic fields to heat themselves, and is usually used in metal heat treatment. The principle is that when a thicker metal is in an alternating magnetic field, an electric current is generated due to the phenomenon of electromagnetic induction.

In the thicker metal, after the current is generated, the current will form a spiral flow path inside the metal, so that the heat generated by the current flow is absorbed by the metal itself, which will cause the metal to heat up quickly.

An air heater is an electric heating device that mainly heats a gas stream. The heating element of the air heater is a stainless steel electric heating tube, and the inner cavity of the heater is provided with a plurality of baffles (deflectors) to guide the flow direction of the gas and prolong the residence time of the gas in the inner cavity, so that the gas can be fully heated, the gas is heated evenly, and the heat exchange efficiency is improved. The stainless steel heating tube of the heating element of the air heater is made by filling the heating wire in the seamless steel pipe, and filling the void part with magnesium oxide powder with good thermal conductivity and insulation.

When the current passes through the high-temperature resistance wire, the heat generated spreads to the surface of the heating tube through the crystalline magnesium oxide powder, and then transmits to the heated air to achieve the purpose of heating.

1. Select the appropriate air heater for the application. This is especially important if operating at high temperatures. When characteristics such as temperature, performance, and efficiency are important, performing an insulation type analysis can help buyers select the right heater for their application.

2. Choose the appropriate air electric heater according to the power. The power selection can be considered from the following two aspects, and only the heater that meets these two conditions is safe and stable.

1. Under working conditions, the calorific value is sufficient to maintain the temperature of the medium.

2. From the initial state, the heating medium is realized to the set temperature (working temperature) according to the specified time requirements

Finned electric heaters, or finned oil heaters.

Air duct heater, which is a kind of electric heater, the power supply it uses is introduced from the contactor in the main power control box, and the user can design the circuit according to their actual needs, so as to control it.

When we use this electric heater, we should pay attention to the following things:

1) Although there is a thermal protector on this electric heater, its function is to automatically cut off the power supply once a situation occurs, but this function is only limited to the case of wind in the air duct, so in other cases, we still have to pay attention to avoid accidents in the heater, which will cause damage to it.

2) Before heating the air duct heater, the relevant components should be checked to see if they are in a normal and usable state. For the power supply of the electric heater, the voltage should be equal to the voltage of the electric heater and should be provided separately.

3) The connection between the electric heater and the control circuit should be made correct before the electric heater can be put into use.

4) Before using the electric heater, all the terminals should be checked to see if they are tightened, if they are loose, they should be tightened, and grounding should be done to ensure the safe operation of the electric heater.

5) At the air inlet of the electric heater, a filter screen should be installed to prevent foreign matter from entering the electric heating pipe, which will damage the electric heating pipe and affect the service life of the electric heater. In addition, the filter should be cleaned regularly.

6) There should be a space distance of not less than 1m when the terminal is installed, so that it can be convenient for repair and maintenance.
