Abstract
A burner and an improved heat recuperator for a burner. The heat recuperator has a tubular body including a plurality of fins extending radially outward from the tubular body. The plurality of fins are disposed in a plurality of segments arranged longitudinally along the tubular body with the plurality of fins in each segment being disposed about a circumference of the tubular body. Adjacent segments of fins being circumferentially offset with one another.
Claims16
A heat recuperator comprising:
- a tubular body, the tubular body including a plurality of fins extending radially outward from the tubular body, the plurality of fins being disposed in a plurality of segments arranged longitudinally along the tubular body, the plurality of fins in each segment being disposed about a circumference of the tubular body, adjacent segments of fins being circumferentially offset with one another, the tubular body including a plurality of depressions extending radially inward from the tubular body between adjacent ring segments, at least one of the plurality of depressions being disposed between adjacent segments of fins,
- wherein the at least one of the plurality of depressions extends at least partially around a circumference of the tubular body along a ring segment, the ring segment extending over a circumferential chord of the tubular body that spans over two or more fins on an adjacent ring segment.
A heat recuperator comprising:
- a tubular body, the tubular body including a plurality of fins extending radially outward from the tubular body, the plurality of fins being disposed longitudinally and circumferentially along the tubular body with adjacent fins in the longitudinal direction being circumferentially offset with one another, a plurality of depressions disposed on the tubular body and extending radially inward from the tubular body, at least one of the plurality of depressions being disposed between adjacent fins in the longitudinal direction,
- wherein the at least one of the plurality of depressions extends at least partially around a circumference of the tubular body along a ring segment, the ring segment extending over a circumferential chord of the tubular body that spans over two or more adjacent fins.
A burner comprising:
- an exhaust housing;
- a recuperator coupled to the exhaust housing, the recuperator having a tubular body and a nozzle, the tubular body including a plurality of fins extending radially outward from the tubular body, the plurality of fins being disposed in a plurality of segments arranged longitudinally along the tubular body, the plurality of fins in each segment being disposed about a circumference of the tubular body, adjacent segments of fins being circumferentially offset with one another, the tubular body including a plurality of depressions extending radially inward from the tubular body, at least one of the plurality of depressions being disposed between adjacent segments of fins,
- wherein the at least one of the plurality of depressions extends at least partially around a circumference of the tubular body along a ring segment, the ring segment extending over a circumferential chord of the tubular body that spans over two or more adjacent fins;
- and
- a fuel tube disposed within the tubular body, the fuel tube including a burner head.
