Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A regenerative tile for a fuel burner comprising, a substantially cylindrical shaped shell, an annular ceramic member mounted within a downstream portion of said shell, said ceramic member having a substantially cylindrical shaped inner surface, a second ceramic member supported within said shell adjacent the upstream end of the first ceramic member by a ring member carried by the shell, said second annular ceramic member having a peripheral surface of smaller diameter than said inner surface providing an annular passage between the perimeter of the second ceramic member and the inner surface of the first ceramic member, said second ceramic member having a central opening therein through which atomized liquid fuel may be projected for combustion within the first ceramic member, and said ring member having circumferentially spaced openings therein for admitting air to said passage.
Claim 2
Dependent Claim
136 words
A regenerative tile for a fuel burner comprising, a substantially cylindrical shaped shell, an annular ceramic member mounted within a downstream portion of said shell, said ceramic member having a substantially cylindrical shaped inner surface, a second ceramic member supported within said shell adjacent the upstream end of the first ceramic member by a ring member carried by the shell, said second annular ceramic member having a peripheral surface of smaller diameter than said inner surface providing an annular passage between the perimeter of the second ceramic member and the inner surface of the first ceramic member, said second ceramic member having a central opening therein through which atomized liquid fuel may be projected for combustion within the first ceramic member, and said ring member having circumferentially spaced openings therein for admitting air to said passage.
Claim 3
Dependent Claim
164 words
A regenerative tile for a fuel burner comprising, a substantially cylindrical shaped shell, an annular ceramic member mounted within a downstream portion of said shell, said ceramic member having a substantially cylindrical shaped inner surface, a second ceramic member supported within said shell adjacent the upstream end of the first ceramic member, said second annular ceramic member having a peripheral surface of smaller diameter than said inner surface providing an annular passage between the perimeter of the second ceramic member and the inner surface of the first ceramic member, said second ceramic member having an arcuate shaped inner surface defining a central opening therethrough of continuously decreasing cross-section with it''s smallest cross-section adjacent to the downstream face of said second ceramic member, means comprising circumferentially spaced ports located within said central opening through which atomized liquid fuel may projected for combustion within the firSt ceramic member, and means adjacent the perimeter of said second ceramic member for admitting air for movement through said passage.
Claim 4
Dependent Claim
164 words
A regenerative tile for a fuel burner comprising, a substantially cylindrical shaped shell, an annular ceramic member mounted within a downstream portion of said shell, said ceramic member having a substantially cylindrical shaped inner surface, a second ceramic member supported within said shell adjacent the upstream end of the first ceramic member, said second annular ceramic member having a peripheral surface of smaller diameter than said inner surface providing an annular passage between the perimeter of the second ceramic member and the inner surface of the first ceramic member, said second ceramic member having an arcuate shaped inner surface defining a central opening therethrough of continuously decreasing cross-section with it''s smallest cross-section adjacent to the downstream face of said second ceramic member, means comprising circumferentially spaced ports located within said central opening through which atomized liquid fuel may projected for combustion within the firSt ceramic member, and means adjacent the perimeter of said second ceramic member for admitting air for movement through said passage.
Claim 5
Dependent Claim
34 words
A regenerative tile according to claim 2 wherein the means for admitting air for movement through said passage includes circumferentially spaced openings in the shell adjacent the upstream end of the first ceramic member.
Claim 6
Dependent Claim
20 words
A regenerative tile according to claim 2 wherein a ring member carried by the shell supports the second ceramic member.
Claim 7
Dependent Claim
22 words
The regenerative tile of claim 3 wherein said ring carries a flange and the second ceramic member is secured to the flange.
