What can flue gas at 750℃ be used for? !

Process: Natural gas is burned to melt aluminum; the natural gas mixes with air and is burned to heat the aluminum ingots. Possible uses: 1. Installing an air preheater, with the flue gas used to supply air; 2. Using the flue gas to heat water (steam is not used in the factory); 3. Waste heat power generation (the volume of flue gas is too small for this purpose). The factory is a manufacturing plant, not a metallurgical enterprise. Do any of you guys have any good suggestions? ~
Why not consider using it as a turbine power source after it is vaporized? Moreover, it is a common design in industry to have vapor generation mechanisms at the rear of similar burners!
CO2 can be used to produce food-grade or industrial-grade liquid CO2, while nitrogen, after purification, can be used as a shielding gas or for instrumentation purposes. This allows waste to be transformed into useful resources through recycling, and heat can be generated to produce hot water; P
Oh, is that so. Steam is generated first, and then the steam drives the turbine, right?
Yes, it’s a very conventional design approach!
Flue gas recycling and oxygen-enriched combustion are employed to significantly reduce natural gas consumption and lower production costs, aided by a heat recovery system
Additionally, the heated flue gas can also preheat the air, reducing fuel consumption!
