Are the high-temperature flue gases generated upon the combustion of phosphorus-containing substances at high temperatures corrosive?
Please explain in detail the causes of corrosion and what substances are responsible for it.
Corrosion is definitely necessary; check the properties of phosphorus pentoxide or phosphorus trioxide
Someone mentioned before that for phosphorus-containing flue gases, the higher the temperature, the greater the corrosivity?
Phosphorus is indeed quite problematic; it’s not the case that higher temperatures lead to greater corrosion, but the water absorption during startup and shutdown must be taken into account
Is it phosphorus that absorbs water or its compounds? How can this be controlled?
High temperatures cause pyrophosphate adhesion, leading to severe corrosion – this is a major challenge in the industry! For boilers that burn yellow phosphorus exhaust gas, those with mature technical solutions can contact me privately.
