Supervision and Significance on the Core Parameters for Steam and Water System in Supercritical Utility Thermal Power Plant

Several core parameters in supercritical thermal power plant were briefly outlined, which had the significance in safe and economic operation. The influence and damage of Cl-, SO42- in steam and water system were discussed, and the mathematical relationship between the cation conductivity and the concentration of Cl-, SO42- was described in room temperature. Meanwhile, the iron transport and deposition in steam and water system was analyzed, according to iron oxide solubility at different temperature and pressure.
