a cavity in fluid communication with the particulate distributor, the cavity comprising a plurality of pipes configured for transmission of a heat transfer fluid therethrough; and
a particulate outlet in fluid communication with the cavity; and
a particulate outlet conveyor.

2 . The heat recovery system of claim 1 , wherein the heat recovery apparatus further comprises:
a heat transfer fluid inlet; an inlet manifold fluidically coupling the fluid inlet and the plurality of pipes; a heat transfer fluid outlet; and an outlet manifold fluidically coupling the fluid outlet and the plurality of pipes.

3 . The heat recovery system of claim 2 , further comprising:
a heat transfer fluid source fluidically coupled with the fluid inlet; and a heat transfer fluid reservoir fluidically coupled with the fluid outlet.

4 . The heat recovery system of claim 3 , wherein the heat transfer fluid reservoir is fluidically coupled with an external energy conversion system.

5 . The heat recovery system of claim 4 , wherein the heat transfer fluid source, the heat recovery apparatus, the heat transfer fluid reservoir, and the external energy conversion system form a closed-loop system.

6 . The heat recovery system of claim 1 , wherein the heat transfer fluid comprises a gas, a liquid or an aqueous solution.

7 . (canceled)

8 . A heat recovery apparatus comprising:
a particulate inlet; a particulate distributor in fluid communication with the particulate inlet; a cavity in fluid communication with the particulate distributor, the cavity comprising a plurality of pipes configured for transmission of a heat transfer fluid therethrough; and a particulate outlet in fluid communication with the cavity.

9 . The heat recovery apparatus of claim 8 , wherein the heat recovery apparatus is configured to couple with a support base via weight bearing members.

10 . The heat recovery apparatus of claim 9 , wherein the heat recovery apparatus is configured to couple with the weight bearing members via a plurality of elastically resilient members.

11 . The heat recover apparatus of claim 8 , wherein the heat recovery apparatus is configured to couple with a mechanical shaker or agitator.

12 . The heat recovery apparatus of claim 8 , further comprising:
a heat transfer fluid inlet; an inlet manifold fluidically coupling the fluid inlet and the plurality of pipes; a heat transfer fluid outlet; and an outlet manifold fluidically coupling the fluid outlet and the plurality of pipes.

13 . A method for recovering heat from hot particulate, the method comprising:
delivering a hot particulate matter to a heat recovery apparatus, the heat recovery apparatus comprising:
a hot particulate inlet;
a hot particulate distributor in fluid communication with the hot particulate inlet;
a cavity in fluid communication with the hot particulate distributor, the cavity comprising a plurality of pipes configured for transmission of a heat transfer fluid therethrough; and
a particulate outlet in fluid communication with the cavity;
circulating a heat transfer fluid through the plurality of pipes; distributing, with the hot particulate distributor, the hot particulate over the plurality of pipes; transferring heat from the hot particulate to the circulating heat transfer fluid; and removing cooled particulate from the heat recovery apparatus through the particulate outlet.

14 . The method of claim 13 , wherein the hot particulate is granulated slag, sand or a ceramic composition.

15 . (canceled)

16 . The method of claim 13 , further comprising:
shaking the heat recovery apparatus.

17 . The method of claim 13 , wherein the heat recovery apparatus further comprises:
a heat transfer fluid inlet; an inlet manifold fluidically coupling the fluid inlet and the plurality of pipes; a heat transfer fluid outlet; and an outlet manifold fluidically coupling the fluid outlet and the plurality of pipes.

18 . The method of claim 17 , wherein the heat recovery apparatus further comprises:
a heat transfer fluid source fluidically coupled with the fluid inlet; and a heat transfer fluid reservoir fluidically coupled with the fluid outlet.

19 . The method of claim 18 , wherein the heat transfer fluid reservoir is fluidically coupled with an external energy conversion system.
