Claims
- 1. Incinerator apparatus with a self-contained preheater for input effluent comprising:
- a generally cylindrical housing having first and second axial ends and further having an inlet and an outlet adjacent the first end;
- a combustion chamber within said housing and offset toward the second end;
- said combustion chamber having a burner and said combustion chamber further being radially spaced from said housing to permit effluent to flow therearound;
- an annular bundle of essentially straight exhaust tubes extending axially within said housing from said combustion chamber to said outlet for conveying hot effluent from said combustion chamber;
- said tubes being loosely spaced apart to permit cool effluent entering said inlet to flow between and around said tubes within said housing;
- at least one annular bulkhead sealingly attached to the interior of said housing and suppoting said tubes and having an open center so that cool inlet effluent may flow through said open center but not around said annular bulkhead;
- at least one solid bulkhead connected to said tubes, radially spaced from the interior of said housing but having a closed center so that effluent may flow around but not through said solid bulkhead;
- said annular and solid bulkheads being axially spaced within said housing between said inlet and said combustion chamber to cause cool effluent to flow repeatedly between and around said tubes enroute from said inlet to said combustion chamber.
- 2. Apparatus as defined in claim 1 further including spacer means connected between the combustion chamber and the interior of said housing for supporting said combustion chamber.
