摘要： PROBLEM TO BE SOLVED: To efficiently recover heat from steam generated in a flash tank. SOLUTION: The heat recovery device for a boiler in a power generation facility comprises a flash tank 90 for raising the temperature of water supply to a boiler 10 together with a high pressure feed water heater 70 in a low output zone of the generator 30 output lower than a rated output zone, a first steam valve B3 provided in a steam pipe S1 for connecting the flash tank 90 and a high pressure heater 70c of the high pressure feed water heater 70, and a second steam valve B4 provided in a steam pipe S2 for connecting the flash tank 90 and a condenser 40. Before reaching the low output zone, opening of the first steam valve B3 is set higher than opening of the second steam valve B4. When reaching the low output zone and a pressure drop in the flash tank 90 is sensed, the valve opening of the second steam valve B4 is set higher than the setting mentioned above.

摘要： PROBLEM TO BE SOLVED: To achieve cost reduction by limiting the range of a heat transfer pipe which uses a high-quality material having high heat resistance in a boiler which is increased in efficiency by increasing the temperature of steam.SOLUTION: In a conventional boiler, an economizer that is set in a front stage of a boiler outlet is removed, and a low pressure reheater 20 is installed instead. Water supply to a boiler 1 is sent first to a water wall 11 on a furnace side. Then, steam that is overheated by first to fourth superheaters 12 to 15 that are high pressure main steam systems is sent to an ultra high pressure turbine 2, and the exhaust air thereof is sent to a high pressure turbine 3. The exhaust air of the high pressure turbine 3 is returned to the boiler 1, and the steam overheated by a primary high pressure reheater 18 and a secondary high pressure reheater 19 that are high pressure reheating steam systems is sent to an intermediate pressure turbine 4. The exhaust air of the intermediate pressure turbine 4 is returned to the boiler 1, overheated by the low pressure reheater 20 that is a low pressure reheating steam system, and is sent to a low pressure turbine 5.
