Compact, high-temperature, low-flow rate, liquid fuel-fired burner

An apparatus for separating solids from a solids and gas flow in a combustor having a fluid circulating system uses a plurality of separators adjacently positioned and horizontally spaced in a path of a solids and gas flow. Each separator includes four tubes. A membrane connected between selected tubes creates a concave-shaped configuration that will capture oncoming solids particles entrained within the flue gas. In one embodiment, fluid from the fluid circulating system flows serially from an inlet into a first leading tube of a first separator through the tubes in each separator in a given row and finally through the second leading vertical tube of a last separator in that row to an outlet and back to the fluid circulating system. Connector tubes communicate with the first leading tube and the first rear tube, the first rear tube and the second rear tube, and the second rear tube and the second leading tube. A separator connector communicates with the second leading tube of one separator and the first leading tube of an adjacent separator. In another embodiment, fluid flows through all of the separators of a given row in parallel by means of inlet and outlet transverse headers.

Water/steam-cooled U-beam impact type particle separator

Water/steam-cooled U-beam impact type article separator

An apparatus and method for sampling gas containing a reactive particulate solid phase flowing through a duct and for communicating a representative sample to a gas analyzer. A sample probe sheath 32 with an angular opening 34 extends vertically into a sample gas duct 30. The angular opening 34 is opposite the gas flow. A gas sampling probe 36 concentrically located within sheath 32 along with calibration probe 40 partly extends in the sheath 32. Calibration probe 40 extends further in the sheath 32 than gas sampling probe 36 for purging the probe sheath area with a calibration gas during calibration.
