METHOD OF OPERATION OF FLOW-TYPE STEAM GENERATOR AND STEAM GENERATOR USED FOR REALIZATION OF THIS METHOD

摘要

FIELD: mechanical engineering. SUBSTANCE: steam generator has combustion chamber with vertical tubes. To exclude negative effect due to irregular heating of separate tubes, it is recommended that densities of mass flow "m" in tubes should be below preset maximum value which depends on tube inner diameter "d". Measures shall be also taken to avoid superhigh temperatures of tube walls near critical pressure of about 200 to 221 bar. Inner side of each tube is provided with surface structure due to which high turbulence and/or longitudinal vorticity in medium of flow, thus providing for proper mixing of flow components and consequently proper heat transfer. EFFECT: enhanced efficiency. 3 cl, 9 dwg
