Abstract :
The economizer is a critical component in coal fired power stations. An optimal renewal strategy is needed for minimizing the lifetime cost of this component. Here we present an effective optimization approach which considers economizer tubing failure probabilities, repair and renewal costs, potential production losses, and fluctuations in electricity market prices.
