Abstract

A gravity-fed housing for use in a gasification system is disclosed. The gravity-fed housing has a receiving end panel that forms a receive opening in a first plane. The receive opening is configured to receive a first plurality of heat carriers via gravity. The gravity-fed housing includes a siding connected to the receiving end panel. The siding forms a chamber and a discharge opening in a second plane that is parallel to the first plane. The discharge opening is offset with respect to the receive opening such that a line perpendicular to the receiving end panel that extends through a center point of the receive opening does not intersect a center point of the second opening. The siding includes a first panel that comprises a guiding surface that intersects the line and is angled toward the discharge opening.

First claim

What is claimed is:

1 . A system comprising:
a gravity-fed housing having a receive end and a discharge end, comprising:
a receiving end panel that forms a receive opening in a first plane, the receive opening being configured to receive a first plurality of heat carriers via gravity; and
a siding connected to the receiving end panel, the siding forming a chamber and a discharge opening in a second plane that is parallel to the first plane, the discharge opening being offset with respect to the receive opening such that a line perpendicular to the receiving end panel that extends through a center point of the receive opening does not intersect a center point of the second opening, the siding including a first panel that comprises a guiding surface that intersects the line and is angled in a direction toward the discharge opening.

2 . The system of claim 1 , wherein the siding further comprises a second panel, a third panel, and a fourth panel, the second panel opposing the first panel and being in a plane that is non-perpendicular to the first plane, the third panel and the fourth panel opposing one another and being perpendicular to the first plane.

3 . The system of claim 2 , wherein the siding forms a purge gas inlet configured to allow a purge gas to enter the gravity-fed housing, and a purge gas outlet configured to allow the purge gas to be discharged from the gravity-fed housing.

4 . The system of claim 1 , further comprising:
a receiving flap mechanism coupled to the receive end of the gravity-fed housing, comprising:
a first flap controller; and
a receiving flap;
wherein the first flap controller is configured to:
selectively open the receiving flap to release the first plurality of heat carriers into the gravity-fed housing via the receive opening, and close the receiving flap to inhibit entry of additional heat carriers into the gravity-fed housing.

5 . The system of claim 4 , wherein the receiving flap, when in a closed position, forms a fluid-tight seal configured to prevent gas from entering or exiting the system via the receiving flap mechanism.

6 . The system of claim 4 , further comprising:
a discharging flap mechanism coupled to the discharge end of the gravity-fed housing, comprising:
a second flap controller; and
a discharging flap;
wherein the second flap controller is configured to:
selectively open the discharging flap to release the first plurality of heat carriers from the gravity-fed housing, and close the discharging flap to inhibit discharge from the gravity-fed housing.

7 . The system of claim 6 , wherein the discharging flap, when in a closed position, forms a fluid-tight seal configured to prevent gas from entering or exiting the system via the discharging flap mechanism.

8 . The system of claim 6 , wherein the siding forms a purge gas inlet configured to allow a purge gas to enter the gravity-fed housing, and a purge gas outlet configured to allow the purge gas to be discharged from the gravity-fed housing.

9 . The system of claim 8 , further comprising:
a purge gas inlet mechanism comprising:
a purge gas inlet controller; and
a purge gas inlet valve;
wherein the purge gas inlet controller is configured to:
selectively open the purge gas inlet valve to allow entry of the purge gas into the gravity-fed housing, and close the purge gas inlet valve to prevent entry of the purge gas into the gravity-fed housing.

10 . The system of claim 9 , further comprising:
a purge gas outlet mechanism comprising:
a purge gas outlet controller; and
a purge gas outlet valve;
wherein the purge gas outlet controller is configured to:
selectively open the purge gas outlet valve to allow discharge of the purge gas from the gravity-fed housing, and close the purge gas outlet valve to prevent discharge of the purge gas from the gravity-fed housing.

11 . The system of claim 10 , further comprising a system controller, the system controller communicatively coupled to the receiving flap mechanism, the discharging flap mechanism, the purge gas inlet mechanism, and the purge gas outlet mechanism, and configured to:
control the receiving flap mechanism, the discharging flap mechanism, the purge gas inlet mechanism, and the purge gas outlet mechanism to:
close the purge gas inlet valve and the purge gas outlet valve;
close the discharging flap; and
open the receiving flap to allow the first plurality of heat carriers to enter the chamber.

12 . The system of claim 11 , wherein the system controller is further configured to:
control the receiving flap mechanism, the discharging flap mechanism, the purge gas inlet mechanism, and the purge gas outlet mechanism to:
close the receiving flap;
open the purge gas inlet valve and the purge gas outlet valve for a first period of time;
close the purge gas outlet valve;
close the purge gas inlet value; and
open the discharging flap to allow the first plurality of heat carriers to be discharged via gravity from the chamber.

13 . The system of claim 12 , wherein the system controller is further configured to:
control the receiving flap mechanism, the discharging flap mechanism, the purge gas inlet mechanism, and the purge gas outlet mechanism to:
close the discharging flap mechanism;
open the purge gas inlet valve and the purge gas outlet valve for a first period of time;
close the purge gas outlet valve;
close the purge gas inlet value; and
open the receiving flap mechanism to allow a second plurality of heat carriers to enter the chamber.

14 . The system of claim 1 , wherein the plurality of heat carriers have an angle of repose, and wherein the guiding surface is at an angle with respect to the second plane greater than the angle of repose.

15 . A system comprising:
a gravity-fed housing comprising:
a receiving end panel that forms a receive opening, the receive opening being configured to receive a plurality of heat carriers via gravity;
a discharging end panel that forms a discharge opening that is eccentric with respect to the receive opening in a direction of gravity;
a siding connected to the receiving end panel and forming a chamber and a discharge opening, the siding including a first panel that comprises a guiding surface configured to guide heat carriers gravity-fed into the receive opening to the discharge opening, the first panel extending from the receiving end panel to the discharge opening.

16 . The system of claim 15 , wherein the second opening is in a plane, and wherein the first panel is disposed at an angle greater than 40 degrees with respect to the plane.

17 . The system of claim 16 , wherein the siding further comprises a second panel, a third panel and a fourth panel, the second panel opposing the first panel and being in a plane that is non-perpendicular to the first plane, the third panel and the fourth panel opposing one another and being perpendicular to the first plane.

18 . A method for controlling the discharge of heat carriers, comprising:
