Regarding the issue of high-temperature heating
Thread Content
To heat the reactor to 400 degrees, what should be used for heating? Is there any good method? It seems that heat transfer oil cannot reach 400 degrees? Seeking help
How about electric heating, or high-pressure steam?
What method should be used for electric heating, since the factory does not have high-pressure steam available?
The simplest way is to use an electric heating element, which works on the same principle as a rapid heater. If conditions permit, direct heating with a burner can be used, which results in lower energy costs.
Electric heating at 400 degrees is completely fine; make sure to do a good job with insulation
It uses far-infrared heating for even heating. I’m worried about uneven heating when using electric heating. Could electrically heated tin be considered, with the temperature of the liquid tin being controlled in order to achieve the desired temperature inside the reaction vessel?
I used to work in an aluminum wheel manufacturing plant; I was in the painting workshop. After powder paint is applied via electrostatic spraying, it needs to be heated to melt and form a paint film, and the same applies to conventional paint – it also needs to be dried. The source of energy for this process is a diesel burner: when heating is required, diesel is injected along with air, and an electric spark is used to ignite the mixture and start the combustion. The high-temperature gas produced by combustion heats the air on the other side through a heat exchanger, which then heats the aluminum wheels.
To what temperature can this gas be heated
To what temperature can this gas be heated
The temperature of heat transfer oil generally does not exceed 300 degrees; I used the high-temperature heat transfer oil from the workshop in pilot tests, and at temperatures of 220–230 degrees, it began to vaporize. At 300 degrees, vaporization is severe, and there is a lot of smoke. It’s not a pilot-scale environment; with the heat transfer oil in place, it can be used. Heat transfer oil is generally used at around 300 degrees Celsius.
At that time it was 180 degrees, as the melting temperature of powder paint is controlled at 180 degrees; if it’s just dried paint, the temperature is 140 degrees. The flue gas temperature is very high. It should be around a thousand degrees.
