Design and simulation of pool kiln for continuous basalt fiber by plasma technology
In response to the problems existing in the production of continuous basalt fibers by pool kiln method,a pool kiln was designed by plasma technology and was calculated and simulated through mathematical models.And the effects of plasma torch power and heating time on the pool kiln temperature were verified through experiments.The results showed that the plasma flame temperature can be adjusted by adjusting the plasma torch power when the plasma technology was applied in pool kiln,so as to make an average temperature of pool kiln reach 1500℃or so,thereby meeting the process demand of melt pool;the plas-ma torch was experimentally applied into the production equipment of the pool kiln method,the entire melt pool reached thermal equilibrium and the bottom and surface temperatures of the pool kiln were maintained at around 1500℃,which can meet the temperature requirements of the fiber solution in the melt pool,when the power of the plasma torch rapidly reached 160 kW and the heating time exceeded 1 h;and the technical parameters such as pool kiln temperature,temperature distribution uniformity and residence time can all meet the production process requirements of basalt fibers when the plasma technology was applied in the production process of continuous basalt fibers by pool kiln method using electricity as a heat source instead of natural gas.
