PRESSURE CHAMBER Russian patent published in 2014 - IPC G21C15/02 

FIELD: power engineering.

SUBSTANCE: invention relates to heat engineering. Pressure chamber 4 comprises cylindrical housing 3 with bottom 2, cylindrical shell 8 and grate 6. Cylindrical shell 8 is arranged coaxially with housing 3 to divide it into central discharge channel 7 and lateral feed channel 1. Grate 6 is arranged in central discharge channel 7. Porosity factor of grate 6 corresponds to the range of 0.05-0.7.Relationships are fine for chamber 4 which allow, first, for interrelation between maximum radius of the grate perforated part, pressure chamber height, cylindrical shell outer radius, pressure chamber inlet height and housing inner radius. Second, interrelation between pressure chamber height, cylindrical shell outer radius, pressure chamber height and housing inner radius. Third, interrelation between pressure chamber inlet height, housing inner radius, inner and outer radii of cylindrical shell 8. Fourth, interrelation between pressure chamber height and that of its inlet. Fifth, interrelation between pressure chamber inlet height, housing inner radius and outer radius of cylindrical shell 8. Invention proposes the relationship for selection of pressure chamber flow section.

EFFECT: optimum flow hydrodynamics at pressure chamber outlet.
