What are the characteristics of air dry burning heating

From the perspective of heating medium, heaters are generally divided into air heating and liquid heating, both of which are widely used. The characteristics of each type are different, and the points of attention for use are also completely different. Today, Yancheng Hongchuang will talk to you about the characteristics of air dry burning heating:

An air heater is an electrical heating device that primarily heats the gas flow. The heating element of the air heater is a stainless steel heating tube, and the inner chamber of the heater is equipped with multiple baffle plates (guide plates) to guide the flow of gas, extend the residence time of gas in the inner chamber, and fully heat the gas, making the gas heating uniform and improving the heat exchange efficiency. The heating element of the air heater is a stainless steel electric heating tube, which is made by inserting electric heating wires into seamless steel pipes, and filling the gaps with magnesium oxide powder with good thermal conductivity and insulation before shrinking the tube. When the current passes through the high-temperature resistance wire, the generated heat diffuses to the surface of the heating tube through crystalline magnesium oxide powder, and then transfers to the heated air to achieve the purpose of heating.

Technical characteristics of air heaters:

1. The heating and cooling rate block can reach 10 ℃/S, and the adjustment is fast and stable. There will be no phenomenon of controlled air temperature leading or lagging, resulting in temperature control drift and uncertainty, making it very suitable for automatic control.

2. Good mechanical performance: Because its heating element is made of specially made alloy material, it has better mechanical performance and strength than any heating element under the impact of high-pressure air flow, which is more advantageous for systems and accessories that require continuous air heating for a long time.

3. It can heat the air to a very high temperature, up to 450 ℃, and the shell temperature is only around 50 ℃.

4. High efficiency: up to 0.9 or above.

5. It is durable and has a lifespan of several decades without violating the usage regulations.

6. Clean air and small volume
