This invention relates to a novel method for controlling the silicon content in boiler water, belonging to the field of water chemistry technology for thermal power plants. The method dynamically determines the allowable silicon content in the boiler water under the current operating conditions based on the real-time boiler operating pressure and a preset negative correlation between boiler pressure and the allowable silicon content in the boiler water. The measured silicon content in the boiler water is compared with this dynamic allowable value, and boiler blowdown is only performed when the measured value exceeds the allowable value. This invention utilizes the physical characteristic that the solubility and carry-over coefficient of silicon in boiler water by saturated steam decreases with decreasing boiler pressure. Under low-load conditions, the control index for silicon content in boiler water is reasonably relaxed, thereby significantly reducing the frequency and amount of boiler blowdown while ensuring steam quality and turbine safe operation. This reduces boiler heat loss and demineralized water consumption, improving boiler thermal efficiency and overall unit economy.
