Abstract
A rotary combustor is disclosed in which a plurality of tubes connect a first header to a second header, and in which the first and second headers have a plurality of baffles dividing them into a plurality of chambers. In accordance with the invention, a branch pipe is located at the extreme end of a first of the chambers for admitting fluid to the first chamber, such that the fluid flows through a first set of tubes to a second chamber and then through a second set of tubes and is returned to another chamber and exits through a second branch pipe disposed at an extreme end of the chamber. The structure made in accordance with the present invention exhibits a relative flow pattern between the chambers that is a counterflow, thereby improving the performance of the combustor. preferably, the tubes are grouped in plurality of pairs of tubes, and the chambers include relatively smaller chambers and relatively larger chambers. In one preferred embodiment, the combustor has an input end and a discharge end, and the relatively larger chambers are disposed at the input end and the relatively smaller chambers are disposed at the discharge end. Preferably, the headers are toroidal ring headers.
