Paper Title:
Causes Analysis and Treatment Measures for Excess SiO2 Content in a 300MW Unit Boiler Water
  Abstract

According to the characteristics of silicon in water, analysis is implemented for the excess SiO2 content in a 300MW unit boiler water. Serious excess SiO2 content in the economizer inlet water and boiler water is caused by high-pressure heater leakage. In addition, SiO2 content increases with the raising feedwater temperature, because colloidal silicon solubility increases with the raising feedwater temperature. Colloidal silicon in water is induced by condenser tiny leakage. High-pressure heater plugging must be handled. Improving activated charcoal filters washing and boiler blow-off frequency can be used to reduce the impact of colloidal silicon on boiler and ensure safe operation of the boiler
