Abstract
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.
Claims18
A burner and fan enclosure for an infrared heater comprising:
- a generally rectangular low pressure housing having a top wall, a bottom wall, opposed side walls and spaced removable, rectangular side panels extending between said top, bottom and side walls;
- an air inlet in one of said side walls;
- a burner outlet in the other of said side walls;
- a high pressure housing within said low pressure housing and having a side aligned with said burner outlet;
- an elongated burner tube within said high pressure housing and having opposed ends, one end extending through said burner outlet;
- a turbulator having plural openings therein arranged about a generally central opening, said turbulator being located at or integral with said other side wall with said generally central opening receiving and supporting one end of said burner tube;
- a generally vertical fuel manifold within said high pressure housing adjacent the other end of said burner tube;
- a fuel orifice in fluid communication with said manifold and aligned with said other end of said burner tube for directing fuel thereinto;
- a centrifugal fan within said low pressure housing and having a volute with a generally central inlet in fluid communication with the interior of said low pressure housing and a discharge outlet mounted to said high pressure housing and in fluid communication with the interior thereof in the vicinity of said manifold and upstream of said orifice;
- a gas control valve within said low pressure housing and having an outlet aligned with said manifold;
- a rotary union interconnecting said control valve outlet and said manifold;
- said low pressure housing having side panel flanges on said top and side walls in or against which said side panels may nest or abut;
- and
- a lock on each side panel near a lower end thereof for removably locking the respective side panel to the low pressure housing.
