Abstract: The flow of the hydrogen has played an important role in the heat exchange in the inner bell. In this research, we have studied the volume distribution of the hydrogen in the inner bell through numerical simulation method, and we get the volume distribution law of the hydrogen when we change the axial angle and the tangential angle of the velocity of the hydrogen flowing into the inner bell while we do not change the speed of the hydrogen. This research could provide theory reference for the design and application of the structure of the coil base of the high performance hydrogen bell-type annealers later.

Abstract: This paper analyzes the current energy structure and coal we use, based on clean coal technology in China, one of the current technology development status and prospects of coal were analyzed, and highlights China's Hunan province a coal for flue-cured tobacco production - biomass briquette mix, production test proved its superior performance, the desulfurization rate, burn rate of more than 90%, respectively, and 98%, suitable for promotion.

Abstract: The heating bell with burners is an important heating device for the high performance hydrogen bell-type annealers. The arrangement of the burners has an important impact on the heating effect. In this study, we simulated a series of model with different location of burners under the same quantity of burners and the same heating power. The result shows: (1) Under the same quantity of burners and the same heating power, when we increase the number of rows of burners, the maximum temperature inside the furnace could be reduced, and the temperature distribution will become more uniform; (2)When we fixed the number of the row of the burners, if we move the upper burners to higher position to make the arrangement of burners more uniform, the temperature distribution inside the furnace will be more uniform, this will be good for the heat transfer to the higher parts of the annealers, and this will accelerate the heating process, improve the efficiency of annealing, reduce fuel consumption, and extend the life of the inner bell.
