| Abstract: | The blowdown effect of a licenced 300 MW set's natural circulation boiler was improved by combining its continuous blowdown system with its emergency water discharging system;whereby the latter was continuously hept warm.A siphon tube was designed for automatic limiting the amount of water discharged in cases of emergency from the drum.Thus an energy saving drainage water recovery system has been designed for raising the set's operational safety and profitability. |
