To get the best efficiency for a combined cycle plant the Heat Recovery Steam Generators (HRSG) operates on with three different pressure circuits. This article explains why this is required.In an HRSG, as in any boiler, water converts to superheated steam in three different sections. The economizer, the evaporator and the Superheater. Heat transfer is dependent on the mass flow of the hot
Three-element Control (Cascade + Feedforward Control) Similar to feed flow, changes in steam flow can also cause large deviations in drum level, and could possibly trip the boiler. Changes in steam flow rate are measurable and this measurement can be used to improve level control very successfully by using a feedforward control strategy.
