Abstract
A gas-fired unit heater (10) is provided and includes a burner (20), a heat exchanger tube (18) located to receive a flow of the combustion products from the burner (20), the tube (18) including at least one linear tube run (30) extending along a longitudinal axis (18), and a corrugated baffle (40) received in the tube run (30).
Claims6
A gas-fired unit heater comprising:
- a burner;
- a heat exchanger tube located to receive a combustion gas flow from the burner, the tube including at least one linear tube run extending along a longitudinal axis, the tube run having an inner wall;
- a corrugated baffle received in the tube run, the baffle comprising a corrugated strip of material having a length extending parallel to the longitudinal axis, and alternating peaks and valleys joined by side walls defining corrugations along the length with each of the peaks and valleys being non-parallel to longitudinal axis.
A corrugated baffle for use in a linear tube run of a gas-fired unit heater:
- the baffle comprising a corrugated strip of material having a length extending parallel to the longitudinal axis, and alternating peaks and valleys joined by side walls defining corrugations along the length with each of the peaks and valleys being non-parallel to longitudinal axis.
