By comparison of the thermal conductivities of air and flue gas under the same temperature, the percentage of C02 may be determined since the thermal conductivity of C02 is considerably less than that of the air, while the differences of other constituents of flue gases are negligible except H2. The gas sample to be analyzed is conducted continuously through leading pipes to filters for the removal of dust particles and harmful S02 gas, and then through a hydrogen burning furnace to burn out the hydrogen if contained in the flue gas. Again passing through the water-cooled condenser, the sampling gas is led to the thermal conductivity cells. Four identical platinum filaments are enclosed in separate cells built in a solid metal block, as shown diagrammatically in fig. 1. fig. 1 Each filament forms one arm of a Wheatstone bridge circuit, and a definite current is allowed to flow through the bridge and heat the platinum filaments to a final equilibrium temperature, which depends upon the cooling condition surrounding the fila- ments. The presence of C02 in the sampling gas reduces the Sanitized Copy Approved for Release 2010/05/06: CIA-RDP80T00246AO46800130001-8 Sanitized Copy Approved for Release 2010/05/06: CIA-RDP80T00246AO46800130001-8 MEAD OFFICE: Er-Li-Kou, Hsi Chino, Peking, China.

The construction is such that the changes in temperature of the metal block affect both sides of the bridge equally. If, there- fore, the cells of R2 and R4 contain air and the cells of Ri and R3 contain air mixed with CO2, the extent of the deflection of a galvanometer in the bridge circuit will be an indication of the amount of C02 present and the galvanometer is calibrated to show directly the percentage of CO2 present. Multi-point recorders or indicators, which can be easily installed, enable data from several sampling points to be obtained on one instrument, which may be any distance from the sampling point.
