Corrosion and Protection of Boiler Flue Gas Recovery and Injection System

Boiler flue gas oil displacement technology can achieve the dual effect of energy conservation and efficiency enhancement, but it will cause a certain degree of corrosion to equipment and facilities during flue gas recovery and injection. Through the analysis and summary of corrosion and protection method of flue gas recovery and injection system, the recovery and injection process of flue gas in gas fired boilers was briefly introduced, the effects of flue gas components, pressure, temperature, flow rate, material and formation water properties on metal corrosion behavior were analyzed in detail, and suggestions for on-site corrosion protection measures of boiler flue gas recovery and injection system and further related research were put forward.
