Simplified method of feed pipe balancing at pneumatic reactor feed
When an industrial process/a reactor is to be pneumatically fed with a solid material via several, simultaneously supplied feed points, one of the requirements is uniform distribution of the solids mass flows. To enable a precise calculation of the individual flows and total flows, numerous parameters are required.
1 Introduction
Various industrial processes are supplied with solid material via parallel pneumatic conveying pipes from several injection points. Normally, it is required that the individual solid material flows are distributed uniformly to the different injection points. The efficiency of this uniform distribution has to be guaranteed. One example for such a process is the feeding of coal dust into blast furnaces for hot metal production. Depending on the capacity of the furnace, the coal dust is pneumatically fed through up to around 40 individual lances arranged around the periphery of the...
