<p>The mass of particulate of an effluent gas (12) flowing in a stack (14) is directly measured with a mass measurement assembly (16) supported within the stack. The mass measurement assembly preferably includes an inertial mass measurement transducer (38) which provides near real-time mass readings. The mass measurement assembly also includes a particulate collector (40) which can be equilibrated in situ. A conditioned gas line (22) supplies clean, dry, heated conditioned gas to the collector for equilibration. The flow rate of the conditioned gas prevents effluent gas from reaching the collector (40) during equilibration. The collector can be equilibrated in the stack before and after sampling and between intermittent sampling periods.</p> |
