Seeking advice on high-temperature heat exchangers
Thread Content
Our facility’s equipment requires high-temperature heat exchangers that can operate at around 900 degrees, with a continuous operating temperature of around 800 degrees. The temperature difference between the hot and cold ends reaches 400-500 degrees. I would like to ask those of you who need to know which material should be used: is it absolutely necessary to use a heat exchanger of the U-tube type? Are there any domestic manufacturers that can customize it? Since we are not in the business of manufacturing heat exchangers, if any company among our friends is able to customize such heat exchangers, please get in touch with me. Thank you very much!
Hehe, I think this waste heat can be utilized. We could look into waste heat boilers to produce some medium- or low-pressure steam, then lower the temperature before condensing it
This is not waste heat; it is the heat from the high-temperature gases in the system that needs to be transferred to other gases. Do you know any manufacturers of heat exchangers?
No, I work with catalysts; I’m involved in design work, as well as work related to sulfur and thermal cracking – so I might be familiar with this area
Do you have any drawings? Our factory specializes in the production of heat exchangers; if you have specific parameters, feel free to contact me at 18363086263. My surname is Peng, and I’m also available on WeChat
Could you tell me about your manufacturing process? Our company, Shandong Kaixiang Heat Transfer Technology Co., Ltd., specializes in the production of heat exchange equipment. My contact number is 13562668600
We are exchanging heat between 820-degree hot flue gas and cold air, with the requirement that the temperature of the cold air reach 600 degrees. Due to the large temperature difference, it is desired to create a U-shaped heat exchanger, using 310S or superalloys as the material.
It needs to be made in the shape of a boiler.
Generally, this type of heat exchange is carried out in stages: the temperature on the hot side is reduced from 800 to 600, from 600 to 400, and from 400 to below 150. The corresponding air and what corresponds to it
We have done around 700 of them; your material will be a bit more expensive
Hello, thank you for your reply! Does \"segmentation\" refer to the use of 1-1 type heat exchangers? Is it to avoid excessive thermal stress? Is it possible to use a double-pass U-shaped heat exchanger? We are concerned that having it divided into multiple sections will result in an excessively large overall volume for the equipment. For materials, what should be used in the high-temperature section? Inconel 625? We use this superalloy in other high-temperature areas of the equipment. Also, are you a heat exchanger company? Can you provide custom solutions and overall plans?
