PRESSURE CHAMBER Russian patent published in 2014 - IPC G21C15/00 

FIELD: heating.

SUBSTANCE: invention relates to power engineering. Pressure chamber (4) comprises cylindrical case (3) with bottom (2), cylindrical shell (8) and grate (6). Cylindrical shell (8) is arranged coaxially with case (3) to divide its chamber into communicated central discharge channel (7) and lateral circular feed channel (1). Grate (6) is located in said central discharge channel (7). At porosity factor of 0.05-0.7 of grate (6) definite ratios exist for pressure chamber (4). These ratios allow for, first, correlation between maximum radius of perforated section of grate (6), height of pressure chamber (4), outer radius of cylindrical shell (8), height of inlet of said chamber (4) and case ID. Second, interrelation of pressure chamber height, cylindrical shell outer radius and pressure chamber inlet height. Third, correlation between case (3) inner radius, cylindrical shell (8) outer and inner radius and pressure chamber (4) inlet height. Fourth, correlation between pressure chamber (4) height and its inlet height. Fifth, correlation between maximum radius of perforated section of grate (6) height of inlet of said chamber (4). Invention cites relationship for selection of pressure chamber (4) flow section sizes that allows for working fluid flow hydraulic characteristics.

EFFECT: optimum hydrodynamics of the flow at pressure chamber (4) outlet.
