ABSTRACT:
A method of detecting leaks in the filter bags of a baghouse filter chamber that includes determining when the filter bags have been cleaned and, during a post-cleaning period after the cleaning of the filter bags, determining whether the opacity level of the exhaust of the baghouse filter chamber exceeds a predefined opacity limit. The determining whether the opacity level of the exhaust of the baghouse filter chamber exceeds a predefined opacity limit may include monitoring the opacity level of the exhaust of the baghouse filter chamber with an opacity sensor during the post-cleaning period and comparing the opacity readings during the post-cleaning period with the value of the predefined opacity limit.
