    摘要: A filtering system for monitoring fluid emissions from a process includes a plurality of filter assembly sections arranged in a parallel fluid flow manner with respect to each other so as to selectively receive a sample fluid (e.g., a sample gas) entering at an inlet of the system. Each filter assembly section includes a filter unit to filter particulate materials from a fluid flowing through the filter, first and second valves disposed at upstream and downstream locations of the filter unit, and a blowback flow path configured to selectively direct a cleaning fluid through the filter unit in a direction that opposes a direction in which the sample fluid flows through the filter unit. Each filter assembly section can be selectively isolated from other portions of the system so as to prevent the sample fluid from flowing through the filter assembly section while allowing a cleaning fluid to be delivered through the blowback flow path of the filter assembly section.

    摘要: A burner assembly having improved flame length and shape control is presented, which includes in exemplary embodiments at least one fuel fluid inlet and at least one oxidant fluid inlet, means for transporting the fuel fluid from the fuel inlet to a plurality of fuel outlets-, the fuel fluid leaving the fuel outlets in fuel streams that are injected into a combustion chamber, means for transporting the oxidant fluid from the oxidant inlets to at least one oxidant outlet, the oxidant fluid leaving the oxidant outlets in oxidant fluid streams that are injected into the combustion chamber, with the fuel and oxidant outlets being physically separated, and geometrically arranged in order to impart to the fuel fluid streams and the oxidant fluid streams angles and velocities that allow combustion of the fuel fluid with the oxidant in a stable, wide, and luminous flame. Alternatively, injectors may be used alone or with the refractory block to inject oxidant and fuel gases. The burner assembly affords improved control over flame size and shape and may be adjusted for use with a particular furnace as required.

    摘要: A method for conducting laser absorption measurements in high temperature process streams having high levels of particulate matter is disclosed. An impinger is positioned substantially parallel to a laser beam propagation path and at upstream position relative to the laser beam. Beam shielding pipes shield the beam from the surrounding environment. Measurement is conducted only in the gap between the two shielding pipes where the beam propagates through the process gas. The impinger facilitates reduced particle presence in the measurement beam, resulting in improved SNR (signal-to-noise) and improved sensitivity and dynamic range of the measurement.
