US Patent:

44050119, Sep 20, 1983

Filed:

Sep 28, 1981

Appl. No.:

6/306554

Inventors:

Richard F. Stockman - Friendship NY

Assignee:

The Air Preheater Company, Inc. - Wellsville NY

International Classification:

F28D 1900

US Classification:

165 10

Abstract:

An open ended basket 20 that contains a mass of heat absorbent material for a rotor of a rotary regenerative heat exchange apparatus. The basket has a uniquely curved support bar 26 at opposite ends thereof adapted to extend obliquely across the mass of heat absorbent material. The support bar is of greater length than the distance between parallel walls of the basket whereby varying the angle at which the support bars extend obliquely away from the contacting walls, each support bar may be made to fit exactly between parallel walls.

Appl. No.:

5/704220

Inventors:

Richard F. Stockman - Friendship NY

Assignee:

The Air Preheater Company, Inc. - Wellsville NY

International Classification:

F28D 1900

US Classification:

165 9

Abstract:

An air preheater comprising a housing that encloses a cylindrical rotor carrying a mass of heat absorbent material alternately between a passageway carrying a stream of hot gas and a passageway carrying a stream of cooler air. Special axially disposed sealing means are disposed in the annular space between the rotor and the rotor housing to preclude fluid by-passing the heat absorbent material of the rotor.

Appl. No.:

6/218895

Inventors:

Richard F. Stockman - Friendship NY

Assignee:

Combustion Engineering, Inc. - Windsor CT

International Classification:

F28F 140

US Classification:

165186

Abstract:

Method and apparatus for enhancing the heat transfer efficiency and lowering the temperature of tube walls used in a tubular gas to gas heat exchanger. The heat exchanger utilizes essentially flat sided tubes for the transfer of heat from hot gas flowing over the tubes to a cooler gas flowing therethrough. The apparatus of the invention includes a metallic heat shield inserted into the tubes between sides thereof to intercept radiation from the outer walls of said tubes and transfer it to the cooler gas flowing therethrough.

Appl. No.:

6/294258

Inventors:

Richard F. Stockman - Friendship NY

Assignee:

The Air Preheater Company, Inc. - Wellsville NY

International Classification:

F28D 1900

US Classification:

165 8

Abstract:

Rotary regenerative heat exchange apparatus having a rotor carrying a mass of heat absorbent element that is alternately exposed to hot and cold fluids. Heat from the hot fluid is first transferred to the cool element, and upon rotation of the rotor is then transferred to the cool fluid flowing therethrough. The rotor and rotor housing that encloses the rotor are supported separately upon independent columns whereby there can be no transmission of force therebetween to induce sympathetic distortion of either the rotor or the rotor housing.

Appl. No.:

5/658147

Inventors:

Richard Franklin Stockman - Friendship NY

Assignee:

The Air Preheater Company, Inc. - Wellsville NY

International Classification:

F28D 1904

US Classification:

165 5

Abstract:

A detector that monitors infra-red ray emission from an air preheater to detect a temperature rise that precedes a fire within the air preheater. The detector of infra-red rays is alternately moved between a "detecting" stage within the air preheater and a "cleaning" stage in clean ambient air where particulate matter deposited thereon by dirty gas may be removed to maintain the detector at a high degree of operating efficiency.

Filed:

Sep 17, 1979

Appl. No.:

6/076056

Inventors:

Richard F. Stockman - Friendship NY

Assignee:

The Air Preheater Company, Inc. - Wellsville NY

International Classification:

F28D 1900

US Classification:

165 9

Abstract:

Rotary regenerative heat exchange apparatus having a rotor of heat absorbent material that is alternately exposed to hot and cold fluids in order that heat absorbed from the hot fluid may be transferred to the cold fluid. The rotor is surrounded by a housing including sector plates at opposite ends of the rotor that are arranged to separate the hot from the cold fluids. Fail safe apparatus is provided to quickly release a sector plate from a position where it is held in close proximity to the rotor whereby a sudden variation of conditions will not permit mutual interference between relatively rotating parts.

Appl. No.:

5/902643

Inventors:

Richard F. Stockman - Friendship NY

Assignee:

The Air Preheater Company, Inc. - Wellsville NY

International Classification:

F28D 1900

US Classification:

165 9

Abstract:

A rotary regenerative air preheater including a housing surrounding a rotor of heat absorbent material that is adapted to rotate between a duct for heating fluid and a spaced duct that carries a fluid to be heated. Sealing means intermediate the rotor and the rotor housing include a torsion spring activated by the moving rotor that is adapted to bias the sealing means axially to provide a barrier that precludes fluid flow between the rotor and the rotor housing.

Filed:

Appl. No.:

6/132958

Inventors:

Richard F. Stockman - Friendship NY

Assignee:

Combustion Engineering, Inc. - Windsor CT

International Classification:

B23P 1526
F28D 1500

US Classification:

291573H

Abstract:

The method of effecting an evacuated space above a quantity of vaporizable fluid contained in a conventional heat pipe. A quantity of vaporizable fluid 10 is admitted into the heat pipe 12 through an inlet assembly to displace residual air in the heat pipe for exhaust through vent 24. When the heat pipe is full of fluid, the inlet assembly including valve 16 and fitting 24 is removed and coupling 26 plugged. Pump 26 having a suction connection to the heat pipe is actuated, and fluid is withdrawn from the heat pipe through check valve 18 leaving an evacuated space to form above a predetermined quantity of vaporizable fluid. A cylindrical standpipe 38 above check valve 18 precludes the evacuation of vaporizable fluid from said heat pipe lower than the upper rim of said standpipe.
