Solutions for Dual Preheating Technology in Blast Furnace Hot StovesI. Current Technical Status at Home and AbroadChallenges in Conventional Domestic Technology:1. Low-Temperature Corrosion from Flue Gas and Blast Furnace Gas (BFG): BFG contains acidic components (Cl⁻, S, etc.), leading to the precipitation of strong acidic water at low temperatures. This causes wet ash clogging, corrodes heat exchangers, resulting in equipment perforation, gas leakage, and safety hazards.2. Low-temperature corrosion of flue gas: If the wall temperature of the heat transfer surface at the f...
