Filed:

Feb 25, 1994

Appl. No.:

8/202232

Inventors:

Frank W. Tsai - San Marino CA
Paul A. Bock - Upland CA

International Classification:

F22B 1500

US Classification:

12223523

Abstract:

A furnace comprising a lower radiant section and an upper convection section, the lower section having associated fuel burners; generally vertically extending first tubular structure suspended in the first section; second tubular structure extending generally horizontally relative to the first section and suspending the first tubular structure; and grid structure extending generally horizontally and supporting the second tubular structure; whereby hot combustion gases produced by the burners flow upwardly in the first section and past the first and second tubular structure and the grid structure to the upper convection section; and the second tubular structures and/or the grid structure are cooled by circulation of fluids therein.

Filed:

May 8, 1987

Appl. No.:

7/047210

Inventors:

Frank W. Tsai - San Marino CA

Assignee:

Kinetics Technology International - Monrovia CA

International Classification:

C10G 920

US Classification:

422111

Abstract:

A hydrocarbon converter furnace has an upper convection heating zone and a lower radiant heating zone, and tubing extends in those zones to convey a fluid hydrocarbon feed and steam in sequence through the convection and radiant heating zones. The tubing includes a feed section and branches therefrom in the radiant section of the furnace, the feed section and branches arranged so that the hydrocarbon and steam flow from the feed section to said branches; also provided is valving for controlling the relative rates of flow in the branches to reduce differential coking in the branches.

Appl. No.:

7/354368

Inventors:

Frank W. Tsai - San Marino CA

International Classification:

F28F 1308
F28F 906

US Classification:

165108

Abstract:

Heat exchanger apparatus for quenching hot hydrocarbon fluid feeds, of different compositions, so as to minimize coking including a shell, and baffle structure in the shell, defining spaced first and second chambers and primary inlet and outlet ports to flow the fluid to and from the shell via the two chambers, the shell and baffle structure also defining a third chamber between the first and second chambers, with secondary inlet and outlet ports communicating with the third chamber to flow quench fluid to and from the third chamber, and pipes of different bore sizes extending through the third chamber, and communicating between the first and second chambers, for passing the hydrocarbon fluid in a selected path or paths via the pipes and first and second chambers, in flowing between the primary inlet and outlet ports.

Appl. No.:

7/523384

Inventors:

Frank W. Tsai - San Marino CA

International Classification:

F27D 1700

US Classification:

432179

Abstract:

A method of operating an industrial furnace, the steps that include providing a process heating zone containing heat exchange tubing for flowing process fluid through the zone; providing first and second fuel combustion zones, and first and second heat regeneration zones; during a first time interval flowing a first stream of air through the first regeneration zone to be preheated therein, flowing the preheated air stream to the first combustion zone to support combustion of fuel therein producing a flame and hot combustion gases, transferring heat from the flame and the hot gases to the heat exchange tubing in the process heating zone, and then flowing the hot gases to the second heat regeneration zone for extracting heat from the gases at the second regeneration zone; and during a second time interval flowing a second stream of air through the second regeneration zone to be preheated therein, flowing the second preheated air stream to the second combustion zone to support combustion of fuel therein producing hot combustion gases, transferring heat from the hot gases to the heat exchange tubing in the process heating zone, and then flowing the hot gases to the first heat regeneration zone for extracting heat from the gases at the first regeneration zone; and repeating the air flow steps, alternately.

Inventors:

Frank W. Tsai - San Marino CA

International Classification:

F22B 3100

US Classification:

1222403

Abstract:

The method of combining two furnaces into one, each furnace having a lower radiant section that includes upright walls and horizontal heat exchanger tubes, and an upper convection section, the lower section having associated fuel burners, including removing the horizontal heat exchanger tubes from the lower section; extending the lower section upright walls vertically upwardly, and providing space between the vertically extended lower sections; providing top walls over the vertically extended lower sections, and providing vertically extending heat exchanger tubing and suspending the tubing vertically within the vertically extended lower radiant sections, to be heated by hot gases produced by combustion of fuel supplied via the burners; and providing and locating an upright convection section of the furnace in flow receiving communication with the lower sections via lateral passages therefrom.

Assignee:

Denali Innovations, LLC - City of Industry CA

International Classification:

B65D 5/38
B65D 59/04
B65D 5/44
B65D 5/42

Abstract:

A child-resistant package comprising a tray and a sleeve. The tray is configured to be inserted into said sleeve. The tray comprises external protrusions and the sleeve comprises one or more internal protrusions and access holes. The internal protrusions are configured to engage with the external protrusions when the tray and the sleeve are in a closed position, such that the tray is substantially prevented from being taken out of the closed position without disengaging the external protrusions from the internal protrusions. Each of the access holes overlaps with an end of each of the external protrusions, such that a user may access and disengage the external protrusions from the one or more internal protrusions, such that the tray is no longer prevented from being taken out of the closed position.
