Stainless steel tubular heater can resist the oxidation of high temperature air
The air heater is a pressure vessel. At the same time, it must resist the oxidation of high temperature air, so the material must be stainless steel. The heating element of the air heater is a stainless steel tubular heater. The heater cavity is provided with multiple baffles, which can extend the residence time of air in the heater cavity to improve the heat exchange efficiency. Properly increasing the number of tubular heater and increasing the installed power of air heaters can shorten the heating time of the production line. The melt-blown process requires higher precision in the temperature control of the draft air heater, and the draft air temperature needs to be stable within the range of ± 1 ° C.
1. The stainless steel tubular heater can heat the air to a very high temperature, up to 850 ° C, and the shell temperature is only about 50 ° C.
2, high efficiency: up to 0.9.
3. Fast heating and cooling rate, up to 10 ℃ / S, fast and stable adjustment. The temperature of the controlled air does not appear to lead and lag, which makes the temperature control drift. It is very suitable for 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 necessary for continuous heating of air for a long time. System and accessory tests are even more superior.
5. Durable without violating usage rules.
