US Patent:

47248238, Feb 16, 1988

Filed:

Sep 29, 1986

Appl. No.:

6/912571

Inventors:

Thomas W. Simpson - Rochester MI

Assignee:

Solaronics, Inc. - Rochester MI

International Classification:

F24C 300

US Classification:

126 39R

Abstract:

A gas fired radiant griddle assembly employing a series of perforated ceramic tiles to define a burner surface positioned beneath the griddle. The center area of the assembled ceramic tiles is blocked off so as to define an annular burner surface to minimize the temperature gradient across the griddle surface and the hot combustion effluents are drawn by convection beneath the griddle surface and out the rear corners of the combustion chamber beneath the griddle to heat the peripheral and corner portions of the griddle and further minimize the temperature gradient across the expanse of the griddle.

Appl. No.:

6/448975

Inventors:

Thomas W. Simpson - Rochester MI

Assignee:

Solaronics, Inc. - Rochester MI

International Classification:

A21B 100
F24C 100

US Classification:

126 21A

Abstract:

A heat exchanger for use with a portable oven. The disclosed heat exchanger maximizes the conversion of heat caloric content of a combustible fuel to useable heat energy. A gas fueled infra-red burner mounted above the heat exchanger directs radiant energy toward a metal plate which also is contacted by waste or effluent from the burner. The metal plate in turn transmits heat by conduction to a sealed passageway or flow path through which air circulates on its way to the oven. By heating the plate with both effluent and radiation approximately 70% of the heat caloric content of the gas fuel is converted to heat energy for heating air in the passageway. Use of a sealed passageway allows conditions inside the oven to be controlled to make the oven suitable for use as a test oven.

Appl. No.:

6/682538

Inventors:

Thomas W. Simpson - Rochester MI

Assignee:

Solaronics, Inc. - Rochester MI

International Classification:

F23D 1312

US Classification:

431326

Abstract:

An infrared heat device utilizing a ceramic burner tile operating in a confined combustion chamber. Inlet gas flow, metered by an orifice, is boosted as required by the air pressure provided in at least approximately Stoichiometric ratio to compensate for increased back pressure.
