  • Combined exhaust gas aftertreatment/air cleaner dust and ejector unit
    Patent number: 8277548
    Abstract: A combined exhaust gas aftertreatment/dust ejector unit (10) is provided for use with a combustion process (14) and an air cleaner (16) of the combustion process (14). The unit (10) includes an elongate housing (30) containing an exhaust gas aftertreatment device (40) and having a radial exhaust gas outlet (34) to direct an exhaust gas flow (12) radially from the housing (30), and a dust ejector (60) including an ejector outlet (62) positioned in the exhaust gas outlet (34). The exhaust gas outlet (34) and the ejector outlet (62) have elliptical shaped cross sections (68,70), with the ejector outlet cross section (70) spaced inwardly from the exhaust gas outlet (34) to define a reduced flow area (72) for the exhaust gas flow (12) to accelerate the exhaust gas flow (12) past the ejector outlet (62).
