Abstract
A method and apparatus for injecting solid particles such as dry ice into an airstream using an airlock having a spherical valve member with spaced through ports and rotatable between an annular seal on one side of the spherical member for feeding the particles to the fluid stream chamber with an annular seal on the opposite side for sealing a particle feed chamber. The airlock device is useful for sealing fluid stream pressure of about 133 Kg/m2 and temperatures of about 350° R.
