The Experimental and Calculation Studies on Steam Temperature Characteristics of Boiler Burning Pulverized Coal and BFG

摘要

The tranditional thermal calculation program cannot satisfactorily reflect the variety steam temperature characteristics of boiler burning mixture of pulverized coal and blast furnace gas(BFG). In order to resolve this problem, the method of combining experimental study and thermal calculation is adopted. The program is checked with a lot of experimental data. The heat transfer coefficient of every main heated surface is corrected. The thermal calculation program is assured and it will become a more dependable basis for the boiler design, operation optimization and econstruction.
