Abstract:
1. A thermoelectric generator assembly for field devices in an industrial process environment, comprising: a thermoelectric generator having a hot junction flange and a cold junction flange, and providing a thermoelectric power output; a heat sink thermally coupled to the cold junction flange, and couplable to the industrial process environment; a process heat source adapter thermally coupled to the hot junction flange and configured to mount to a combustion chamber of an industrial process and having a process heat pickup which extends into the combustion chamber whereby the combustion chamber provides a process heat source; a movable shutter provided in the combustion chamber to vary shielding of the process heat pickup; and the process heat pickup extracting heat from the process heat source such that the thermoelectric power output is sufficient to energize at least one field device, wherein the heat sink comprises a pressurized plant air inlet, a pressurized plant air outlet and an internal passageway connecting the pressurized plant air inlet and pressurized plant air outlet, wherein the pressurized plant air inlet and pressurized plant air outlet are configured to connect with a pressurized air line carrying pressurized plant air to a plant air utilization device.
