摘要

本文综述了用于煤粉燃烧场数值模拟的脱挥发模型和烟尘形成模型的研究进展,以及煤粉燃烧场烟尘颗粒测量技术的研究进展。对于新模型的开发,由于未经验证的新模型有可能在模拟中产生较大的误差,因此必须使用测量对已开发的模型进行验证,以检查模型的准确性。建立了考虑颗粒加热速率对挥发物量和脱挥发速率参数影响的表化脱挥发过程模型(TDP模型)。利用煤燃烧试验炉的激光多普勒测速数据,验证了所建立的TDP模型的准确性。提出了结合TDP模型的大涡模拟烟尘形成模型。利用激光诱导白炽灯(LII)和激光诱导化学发光(PAHs-LIF)测量了煤烟体积分数和多环芳烃的空间分布。利用实测数据验证了所建立的煤烟形成模型的准确性。

Coal Particle Devolatilization and Soot Formation in Pulverized Coal Combustion Fields
In this paper, recent developments of the devolatilization model and soot-formation model for the numerical simulations of pulverized-coal combustion fields, and the technology used to measure soot particles in pulverized-coal combustion fields are reviewed. For the development of new models, the validation of the developed models using measurement is necessary to check the accuracy of the models because new models without validation have a possibility to make large errors in simulations. We have developed the tabulated devolatilization process model (TDP model) that can take into account the effect of particle heating rate on the volatile matter amount and the devolatilization-rate parameters. The accuracy of the developed TDP model was validated by using the laser Doppler velocimetry data for the bench-scale coal combustion test furnace. The soot-formation model combined with TDP model for the large eddy simulation (LES) has been also developed. The spatial distributions of both the soot-volume fraction and the polycyclic aromatic hydrocarbons were measured by virtue of laser-induced incandescence (LII) and laser-induced chemiluminescence (PAHs-LIF). The accuracy of the developed soot-formation model was validated by using the measured data.
