Gas turbine heat recovery steam generator NecessityOver the past decade,Website:http://www.chinawasteheatboiler.com, more and more gas turbine power plant owners in developing nations and nations that are rich in oil reservation began to modify their plants to increase power output. By installing a secondary heat recovery unit (HRSG) to recover the waste heat from the fossil fuel turbine, the overall power efficiency can be increased by 50 % to 60%.   Design IngenuityThe exhaust gas from the gas turbine is large in quantity and the heat recovery steam generator is required to possess a prompt start-stop time. Therefore, the design the of the HRSG needs to be meticulously thought out. Our HRSG system adopts a horizontal prefabricated module structure, in which the heat surface area employs a multi-free-end-surface design to offset material heat expansion due to quick start and stop. The heat exchange surface area employs a slotted spiral-fin design to further enhance thermal conductivity. The average investment recovery period is around 2 years. Key ParametersRated steam pressure: 1.0 MPA ~ 9.8MPARated steam temp: saturated steam temp ~ 540℃
