Can a waste heat boiler produce more superheated steam by increasing the inlet water temperature?

Can a waste heat boiler produce more superheated steam by increasing the inlet water temperature? Currently, the flue gas inlet temperature is 400 degrees Celsius, with a flue gas flow rate of 280,000 cubic meters per hour; the outlet temperature is 130 degrees Celsius, and the water inlet temperature is 25 degrees Celsius. The system produces 15 tons of steam at 1.2 Mpa and 280 degrees Celsius per hour. If the inlet water temperature is 90 degrees, can more superheated steam be produced? If possible, by how much more? I would appreciate some guidance from an expert teacher.
No! Only by reheating the steam into superheated steam!
Thank you so much! One more question: can a heat exchanger be used to produce low-temperature steam at 130 degrees using a flue gas heat source of 155 degrees? Thank you!
Isn’t what you’re producing now just superheated steam? The amount of steam produced is related to the rated evaporation capacity of the waste heat boiler; what is its evaporation capacity?
