Selection of external heating methods for reaction vessels
Thread Content
At present, it is necessary to heat 15 cubic meters of alkaline solution in the reactor from 120 degrees to 200 degrees within one hour. I’m not sure which heating method would be the most reliable Jacket steam or heat transfer oil? Or far-infrared?
The question is not clear: is it static heating, meaning no circulation of the alkaline solution for heating, or is external circulation of the alkaline solution used for heating? If it is static heating, then factors such as heat transfer efficiency and the heat-carrying capacity of the heating medium need to be taken into consideration. For a heating temperature difference of 80°C, it is recommended to use a steam jacket; steam has a high latent heat. Heat transfer oil suffers from poor heat transfer efficiency due to its limited heat exchange area. Far-infrared heating has not been used before, so no comment can be made on it
If the facility has a suitable steam source, using steam is more economical; otherwise, heat transfer oil should be used.
Circulating heat transfer oil, non-circulating heat transfer oil with electric heating, steam heating, electric heating.
