How is condensate polishing applied in gas-fired plants?

In gas-fired power plants, condensate polishing is applied to purify the return condensate used in steam cycles. During the operation of gas-fired plants, impurities such as dissolved salts, silica, and corrosion products can accumulate in the condensate. These impurities, if not removed, can cause scaling, fouling, and corrosion in boilers and turbines, reducing plant efficiency. Condensate polishing systems remove these impurities, ensuring that the water fed into the boiler is of high purity. This process helps maintain the integrity of the steam cycle, enhances plant efficiency, and reduces maintenance costs.
