Abstract
A filter probe for sampling components of a stack gas which includes means for extracting a flow sample of the stack gas, means for inertial filtering of the flowing stack gas sample extracted by the extracting means, means for collecting the flowing stack gas sample after filtering by the filtering means, means for conditioning the filtered and collected stack gas sample based on predetermined criteria such as cooling and drying, and means for flowing the filtered and collected stack gas sample from the collecting means to the extracting means so that a constant flow of the filtered stack gas sample is presented to the conditioning means to permit essentially instantaneous analysis of the stack gas sample.
Claims24
A filter probe for sampling components of a stack gas comprising:
- means for extracting a flowing sample of said stack gas, said extracting means having a flow input and a flow output, said flowing sample flowing from said flow input to said flow output;
- means for filtering said flowing stack gas sample extracted by said extracting means, said filtering means being in communication with said flowing sample in said extracting means;
- means for collecting said flowing stack gas sample after filtering by said filtering means, said collecting means being in communication with said flowing stack gas sample after filtering by said filtering means;
- means for conditioning said filtered and said collected stack gas sample based on predetermined criteria, said conditioning means being in communication with said collecting means;
- and
- bypass means for flowing a portion of the filtered and collected stack gas sample from said collecting means to said flow output of said extracting means bypassing said conditioning means so as to permit a constant flow of said filtered stack gas sample to said conditioning means, said bypass means being in communication with said collecting means and said flow output of said extracting means.
