Abstract

One of notable features of supercritical CO₂ Brayton cycle is that it needs recover a large amount of exhausted heat for achieving higher cycle efficiency, which makes the inlet temperature of primary heat exchanger (boiler) much higher than that of the conventional steam Rankine cycle. Compared with the supercritical steam boiler, the supercritical CO₂ boiler owns remarkable features:higher inlet temperature, higher proportion of the reheat quantity, working far from the large specific heat region. Hence, it is necessary to study the thermal fluid dynamic characteristics and wall temperature distribution of supercritical CO₂ boiler in depth. Using a 300MW, 600℃ once reheat supercritical CO₂ boiler as an illustration, the thermal fluid dynamic characteristics were analyzed in detail in the present paper, according to the numerical simulation and hydrodynamic calculation. Then, the distributions of mass flow rate, working fluid temperature and gas wall temperature were obtained.
