FIELD: chemical or physical processes.
SUBSTANCE: gas analyzer comprises housing (2) that receives solid-fuel charge (3), igniter (5), and filter-cooler (7) made of gas-permeable coarse-grained powder (8) whose grain size ranges from 0.13 to 0.5 mm. Filter-cooler (7) is provided with gas-permeable disks (14) arranged perpendicular to its axis. The disks are made of a material whose thermal conductivity exceeds that of dispersion powder (8) by a factor of 15. The temperature of melting, decomposition, or sublimation of dispersion powder (8) exceeds the temperature of the products of combustion of solid-fuel charge (3) by 20%. The length of filter-cooler (7) ranges from 100 to 2500 of the mean size of the particles of powder (8) of the filter-cooler.
EFFECT: reduced temperature and contamination of combustion products.
