Cooling of high-temperature furnace gas, help! !
Thread Content
The company has newly developed a device for high-temperature vacuum carbo-reduction of metal oxides, which produces metal vapor and CO; this device is intended to condense the gas streams in order to recover the metal. I was wondering if there are any friends with experience in this area. The furnace temperature is around 2000 degrees; is there any equipment or design for directly cooling or exchanging heat with the gases generated at such a high temperature?
1 Generally, waste heat boilers are used to cool flue gas, but they cannot be used to “separate metals””； 2 Ordinary heat exchangers cannot be exposed to high-temperature gases. I recommend seeking experts with original technical skills, or experts from abroad.
So, may I ask what the highest temperature of the furnace gas that the heat exchanger can withstand is?
It is the “boiler” that bears the high-temperature flue gas, not the “heat exchanger”.
Well, a heat exchanger must have a certain temperature, right? Different heat exchangers can tolerate different inlet temperatures. Are you not answering the question here, dude!
According to available information, the operating temperature of shell-and-tube exchangers abroad can reach 1000–1500 degrees, while that of coil-type exchangers is 800 degrees
