Abstract:This paper presented the current status of high-temperature and high-pressure alkali recovery boilers in China, highlighting three key challenges faced by these boilers: metal corrosion of heating surfaces (e.g., water wall corrosion, superheater corrosion), improving combustion efficiency, and reducing pollutant emissions, along with corresponding mitigation strategies. It also explored potential future directions for the development of alkali recovery boiler technology.
