ABSTRACT:
A gas sampling analyzing system is provided whereby flue or process gasses are aspirated from a process duct to an analyzer and are therefrom returned back to the process duct to prevent condensation at the system exhaust. The sampling analyzing system is enclosed in an internally heated manifold to prevent condensation of the sampled gas and insure an accurate analysis by the system. The sampling analyzing system has an analyzer assembly connected in parallel with a drop tube with the combination being connected to a sample probe on one side and to a supply air operated aspirator on the other side. The parallel drop tube allows a high flow rate to be maintained between the sample probe and the aspirator to ensure a faster system response to changes in concentrations of the flue or process gasses.
