Regarding high-temperature heating.
Thread Content
I would like to ask everyone what kind of devices are generally used in actual production or design processes where high-temperature heating media are required, such in situations where the temperature is above 500 degrees. High-power electric heaters seem to tend to break down after being used for a long time, and the oil circulation system requires complicated maintenance. What do people usually use? Could you talk about the advantages and disadvantages in terms of usage? Thank you! :handshake
Select the heater based on the required heat load: 1. For high loads, use a heating furnace; for example, to reach temperatures above 500 degrees in a reforming process, a four-in-one furnace (with bottom and side heating) is suitable； The hydrogen production converter is heated to over 780 degrees, using a top-fired furnace ； ⒉When the load is low, an electric heater can be used; to heat the reforming catalyst regeneration air to 565 degrees, with a heat load of 70 KW, an electric heater is selected.
In actual industrial production, for heating at temperatures above 500 degrees, direct fire heating is seemingly the method commonly used； Of course, using modern large electric heating strips should also work, and they allow for temperature control. :loveliness:
Electric heating: easy to obtain the source material, and the technology is mature and reliable. For combustion furnaces, however, the source of fuel needs to be taken into consideration. As for heat transfer oil furnaces, it’s necessary to determine whether they can reach the desired temperature
