Patent ID: 8261551

Claim:
A device comprising: a tubular heat exchanger section to provide a biodegradable heat exchange oil, the tubular heat exchanger section having a first end and a second end; and a thermal riser having a first end and a second end, the first end of the thermal riser being attached to the second end of the tubular heat exchanger section, the thermal riser to receive the heat exchange oil from the tubular heat exchanger section and to heat the heat exchange oil based on a resource, wherein the thermal riser includes a thermal riser pump and a thermal riser pump housing to house a heat transfer pump, a plurality of thermal riser sensors and a plurality of thermal riser sections, wherein a first one of the thermal riser sections is coupled to a second one of the thermal riser sections, and the first thermal riser section includes: a first outer spiral pipe section to circulate the heat exchange oil in a downward manner, and a first inner return pipe section provided inside the first outer spiral pipe section to receive the heat exchange oil after the heat exchange oil passes through the first outer spiral pipe section, wherein the first inner return pipe section provides heated heat exchange oil, wherein at least one of the sensors provides an indication of temperature of the heated heat exchange oil, and wherein the heat transfer pump in the thermal riser adjusts a speed based on the temperature of the heated heat exchange oil.
