What is the maximum permissible temperature of the biphenyl furnace

Pay attention to the vapor pressure.

2.Biphenyl is oil-(257) gas-oil system heat transfer oil is a liquid system The pipeline design is different, the requirements are different,-- the vapor biphenyl heating is very stable, and it is widely used in the chemical fiber industry, but the requirements are very strict (very toxic).

Biphenyl furnace is a kind of heating furnace, generally electrically heated, with a mixture of biphenyl and diphenyl ether added. Used to conduct heat. It is widely used in the chemical fiber industry.

You may have problems with your boiler such as:

1. The combustion condition of the boiler is not good.

2. The insulation of boiler pipes or equipment is not done.

3. The boiler selection is smaller.

Biphenyls for chemical fibers are divided into room temperature biphenyls and low temperature biphenyls, the difference is that their boiling points are different.

There are generally no special requirements for the heating steps, just don't set the set temperature too high at once, to prevent the addition of ** or relay due to overcurrent burning. Therefore, the specific steps of heating are generally used to rise to 100 degrees Celsius first, and then rise to 50 degrees Celsius after a constant temperature. until it reaches the target temperature.

In addition, biphenyls are usually heated the day before the drive, because it takes a long time to keep the temperature in the system constant.

The performance indicators of the high-temperature furnace are as follows:

Heating method: electric heating.

Calcined products: powder materials.

Operating temperature: 60 —1400

Temperature control accuracy: 2

Therefore, up to 1400 can be used

Generally, it is more than 300 degrees, and some can reach more than 500, and there are relatively few in China.

Heat conduction oil boiler, liquid phase, generally not more than 330.

Even the Daosheng furnace of this diphenyl ether can reach 400.

Molten salt oven, higher.

The maximum operating temperature of heat transfer fluid is determined according to the specific type and composition of heat transfer oil.

At present, high-temperature heat transfer oil mainly includes dibenzyltoluene and hydrogenated terphenyls, etc., and the maximum use temperature is 360

If it is higher, the heat transfer oil is not suitable, and molten salt must be used as a heat carrier.

Generally speaking, the maximum source temperature of the 1800W induction cooker can reach BAI270 degrees, and the induction cooker with electricity will not heat up without metal pots and pans. After putting the iron pot, if the iron pot is boiling water or soup, the temperature will not exceed 100 degrees, and the temperature of the pot itself can only be slightly higher than the water; The temperature of boiling oil must exceed 100 degrees to reach the boiling point or even the ignition point of the oil.

Induction cooker, also known as induction cooker, was born in Germany in 1957 as the first household induction cooker. In 1972, the United States began to produce induction cookers, and in the early 80s of the 20th century, induction cookers began to sell well in Europe, America and Japan.

The principle of the induction cooker is the phenomenon of electromagnetic induction, that is, the alternating current is used to generate an alternating magnetic field that changes the direction through the coil, and a vortex current will appear inside the conductor in the alternating magnetic field (the reason can refer to Faraday's law of electromagnetic induction), which is caused by the movement of the carriers in the conductor (the electrons in the pot are not iron atoms) driven by the vortex electric field; The Joule heating effect of the vortex current heats up the conductor and thus heats up.

The specific situation depends on the band or frequency you adjust, generally speaking, the maximum temperature of the 1800W induction cooker can reach 270 degrees, if it is a dry pot, it will last about 70 seconds to burn the pot red, and the panel can withstand the temperature of 650 degrees, but it will not reach this temperature.

The power of the induction cooker WDC-2000 is 2000W, the maximum temperature is not very easy to say, the maximum boiling water is 100 degrees, the maximum frying is about 280 degrees, and it is higher if the dry pot is boiled.

The induction cooker is still good for Shang Pengtang.

Founded in Keelung, Taiwan in 1985, Shang Peng Tang International Group started with the research and development of induction cooker products, and is the earliest professional manufacturer of induction cooker in China. With 20 years of professional induction cooker R&D and manufacturing experience, Shang Pengtang induction cooker has a market share of more than 65% in the United States, and leads the Taiwan induction cooker market with a market share of 70%, and in 2002, it won the first place in the reputation evaluation of China's induction cooker market organized by the China Center for Commerce, Economy, Science and Technology Information, and became one of the world's largest induction cooker manufacturers.
