Seeking help with flue gas heat dissipation issues
Thread Content
The flue gas temperature is 300°C, and it needs to be reduced to 100–150°C. Can two sets of U-shaped surface coolers with a pipe diameter of 1 meter and a length of 12 meters meet this requirement? Seek the calculation method for pipe heat dissipation
How should the fan pressure be selected? There are 40 meters of carbon steel pipes with a diameter of 1 meter, 4 180° elbows, and 3 90° elbows. What is the total air resistance?
If the amount of flue gas is high, waste heat recovery for power generation can be utilized

This is very simple. . . . It mainly depends on the amount of flue gas. A heat exchanger can solve this problem. Additionally, considering the issue of the heat transfer medium, if the amount of flue gas is too large, our company’s latest technology utilizing liquid metal as a heat transfer medium can be employed; its thermal conductivity is 50 times that of water and 30 times that of heat transfer oil. Traditional water and oil require heat exchangers with a large heat exchange surface area, while the use of liquid metals can effectively avoid this problem. Moreover, the convective heat transfer efficiency is extremely high at 20,000 (W/m2*K). Water, on the other hand, has a value of only 400 (W/m2*K). Additionally, liquid metals do not experience changes such as phase transition or pressure expansion at high temperatures, allowing for precise temperature control. Also, does your smoke contain sulfur dioxide and sulfur trioxide? If necessary, consider the dew point corrosion temperature.

.........Dude, spraying water isn’t actually a good way. It’s better to use a plate exchanger to heat the air before feeding it into the combustion furnace, right? It can also save natural gas. It’s best not to spray water if possible; what do you think?

Yeah, just install a heat exchanger; it mainly depends on the flow rate and the benefits it brings
