Factors regarding the heat recovery steam generator (HRSG) have drastically changed in the development of the gas turbine and needs of a higher thermal efficiency in recent years.In the early 90's, gas turbine firing temperature increased from 1000°C which established in the 70's, to 1300°CAs a result, plant thermal efficiency improved from 40% to around 49% due to increasing the capacity of HRSG and the adoption of higher steam conditions in the reheat/triple-pressure system instead of the conventional non-reheat/single pressure system.Here, subjects of the performance, system, structure and control in reheat/triple-pressure type HRSG are reported.
