Abstract
Abstract A compact, precise gas calorimeter is described comprising a sintered metal walled enclosure, a plenum in flow communication with one wall of the enclosure for receiving a metered gaseous fuel/air mixture, an igniter located adjacent the inside of the one wall, means embedded within each wall of said enclosure to provide for passage of a metered coolant flow through the interior of each of said walls and means located in the inlet to and outlet from said coolant passage means for determining the differential in temperature between the incoming and outgoing coolant flow. During operation the one wall functions as a plug burner, while the rest of the wall surface of the enclosure serves as condenser area.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
142 words
A gas calorimeter comprising in combination, a. a completely enclosed walled container having a plurality of sintered metal porous walls, b. a plenum in flow communication with one porous wall of said container, c. first means in flow communication with said plenum for metering gas fuel input thereto, d. second means in flow communication with said plenum for metering air input thereto, e. means located within said container adjacent said one wall for igniting a combustible mixture of air and fuel passing through said one wall from said plenum, f. means embedded within each porous wall of said container for circulating a liquid coolant at a known rate of flow therethrough to controllably cool said each porous wall and g. means interconnected with inlet and outlet ends of said coolant circulating means for determining temperature differentials between incoming and outgoing coolant flows.
Claim 2
Dependent Claim
142 words
A gas calorimeter comprising in combination, a. a completely enclosed walled container having a plurality of sintered metal porous walls, b. a plenum in flow communication with one porous wall of said container, c. first means in flow communication with said plenum for metering gas fuel input thereto, d. second means in flow communication with said plenum for metering air input thereto, e. means located within said container adjacent said one wall for igniting a combustible mixture of air and fuel passing through said one wall from said plenum, f. means embedded within each porous wall of said container for circulating a liquid coolant at a known rate of flow therethrough to controllably cool said each porous wall and g. means interconnected with inlet and outlet ends of said coolant circulating means for determining temperature differentials between incoming and outgoing coolant flows.
Claim 3
Dependent Claim
18 words
The gas calorimeter as recited in claim 1 wherein the one wall may be removed from the container.
Claim 4
Dependent Claim
14 words
The gas calorimeter as recited in claim 1 wherein the sintered metal is copper.
Claim 5
Dependent Claim
17 words
The gas calorimeter as recited in claim 1 wherein said coolant circulating means is one continuous conduit.
Claim 6
Dependent Claim
33 words
The gas calorimeter as recited in claim 1 wherein the pluralIty of container walls consist of a flat wall as the one wall together with wall area generated as a surface of revolution.
Claim 7
Dependent Claim
25 words
The gas calorimeter as recited in claim 1 wherein that wall area other than the one wall is in the form of a flat-bottomed cylinder.
Claim 8
Dependent Claim
16 words
The gas calorimeter as recited in claim 6 wherein the cylinder is a right circular cylinder.
Claim 9
Dependent Claim
19 words
The gas calorimeter as recited in claim 1 wherein the means for determining temperature differentials includes a differential thermocouple.
Claim 10
Dependent Claim
35 words
The gas calorimeter as recited in claim 1 wherein the sintered metal is metallic shot material having a thermal conductivity at least 30 percent of the value of the thermal conductivity of sintered copper shot.
