A Study of Blast Furnace Gas-fired 50 MW High-pressure Boiler

A detailed discussion was conducted concerning a blast furnace gas fired 50 MW high pressure boiler. Expounded were the combustion technology, which can promote the stable ignition of a blast furnace gas fired boiler, and the latter's structural design features. After an analysis of the influence of blast furnace gas firing on the boiler's thermodynamic parameters, heat transfer characteristics and heating surface layout the authors have proposed a layout scheme suitable for a blast furnace gas fired boiler. The first blast furnace gas fired 50 MW boiler in China has been manufactured based on the above study results. Its successful operation experience indicates that with the blast furnace gas firing related pollution issues effectively resolved this type of boiler will enjoy broad prospects of application in metallurgical industries.
