    摘要: A burner and fan enclosure for an infrared heater includes a low pressure housing 10 with an internal high pressure housing 24. A centrifugal fan 39 is located within the low pressure housing 10 and provides combustion air to the high pressure housing 24. Removable side panels 20,22 for the low pressure housing 10 may be removed for servicing and/or adjustment of the unit without affecting combustion characteristics allowing the unit to be adjusted while in operation.

    摘要: Poor heat exchange in a heat exchanger between a flue gas passing through the heat exchanger and air being forced through the heat exchanger can be improved in a heat exchanger and combustor (30) for exchanging heat between a forced air stream and a flue gas generated by a plurality of spaced, parallel burners (44) with a construction including spaced, upper and lower headers (32, 34), a plurality of tubes (50), one for each burner (44) extending in parallel between and mounted to the headers (32, 34). Each tube 50 has a first section (56) of enlarged cross section adapted to serve as a combustor for fuel to generate the flue gas and a narrowed, second section (70) for exchanging heat between the flue gas and the forced air stream. Each second section includes generally flat, parallel spaced walls (58, 60) with each of the walls (58, 60) having dimples (74) therein which are directed toward the other of the walls (58, 60) into substantially contacting or almost contacting relationship therewith.
