Analysis and Improvement of the Thermal Power Unit Deaerator Standard Dissolved Oxygen
Small thermal power unit without the turbine generator, deaerator and boiler feed water system prone to be in the state of dissolved oxygen substantially exceeding , this is a serious threat to the safe operation of the boiler＇s heated surfaces and the equipment＇s life. Through the analysis and investigation of excessive dissolved oxygen in the deaerator and feedwater systems, the threat above is caused by the recycled water. When changing the forms of water pump seal into the mechanical seal, the oxygen content of the deaerator and feedwater systems dropped significantly. To the pure Thermal Power Unit without turbine , the mechanical seal is recommended to the pump. When equipment operating problems arise, you should consider the structural characteristics of the individual equipment and the process of the entire system.
