Abstract:
    A method of detecting leaks in the filter bags 106 of a baghouse filter chamber 101 that includes determining when the filter bags 106 have been cleaned and, during a post-cleaning period after the cleaning of the filter bags 106, determining whether the opacity level of the exhaust of the baghouse filter chamber 101 exceeds a predefined opacity limit. The determining whether the opacity level of the exhaust of the baghouse filter chamber 101 exceeds a predefined opacity limit may include monitoring the opacity level of the exhaust of the baghouse filter chamber 101 with an opacity sensor 112 during the post-cleaning period and comparing the opacity readings during the post-cleaning period with the value of the predefined opacity limit.
