Abstract
A process heater system (10) for an industrial envelope (11) comprises a main combustion chamber (20), an afterburner (30), and an exhaust stack (40). Retrofitted heat-recovery piping (50) receives combustion gas downstream of the afterburner (30) and uses it as a heat source for the industrial envelope. When the industrial load in the main combustion chamber (20) is paint, powder coating, varnish, epoxy, grease and/or oil, the secondary materials burned in the afterburner 30 can be considered alternative fuel, not solid wastes.
Claims20
A process heater system (10) for an industrial envelope (11), comprising:
- a main combustion chamber (20) wherein an industrial load is combusted;
- an afterburner (30) comprising a supplemental combustion chamber (31) in communication with the main combustion chamber (20) and a second zone (33) in communication with the supplemental combustion chamber (31);
- an exhaust stack (40) receiving combustion gas from the second zone (33) of the afterburner (30) and exhausting it outside the industrial envelope (11);
- and
- heat-recovery piping (50) receiving combustion gas downstream of the second zone (33) the afterburner (30) and transmitting it for use within the industrial envelope (11), whereby material combusted in the afterburner (30) is fuel used to provide energy for the industrial envelope (11).
