Study embodies assessment of outlet emission in the baghouse exhaust while hole appears on filter due to pyrophoric particles during hot gas filtration or damages due to cages. As it is difficult to study full-scale baghouse, flat PTFE coated polyester filter fabric has been tested in the present study. Experimental research has been carried out to observe and understand the emission behavior of leaks throughout the filtration time. After stabilization of media, the effect of three independent parameters has been used for the study of hole diameter, position of hole and face velocity. The behavior of emitted particles has been studied based on the data generated during online particle measurement system. The experiment leads to the inferences that with increase in hole size, the rate of outlet emission increases but in different manner. Smaller diameter hole does not make prominent effect to position with the face velocity. At all level of hole size, progressive increase in emission and peak pressure have been observed with the face velocity.

泄漏对脉冲喷射清洁辅助过滤系统中织物过滤器性能的影响

这项研究体现了对袋式除尘器排气口中排放物排放的评估，而在热气过滤过程中由于发火性颗粒或滤笼引起的损坏，过滤器上出现孔洞。由于难以研究大型布袋除尘器，因此在本研究中已经测试了扁平的PTFE涂层聚酯滤布。已经进行了实验研究，以观察和了解整个过滤时间内泄漏的排放行为。在介质稳定之后，三个独立参数的作用已用于研究孔直径，孔位置和面速度。已基于在线粒子测量系统生成的数据研究了发射粒子的行为。实验得出的结论是，随着孔尺寸的增加，出口发射率会增加，但方式会有所不同。较小直径的孔不会随面速度对位置产生显着影响。在所有孔尺寸的水平上，随着面速度观察到了发射和峰值压力的逐渐增加。
