Abstract
A thermal power plant is proposed for achieving high reliability, low material cost, and low construction cost by devising the arrangement and structures of a boiler, steam turbines, and a flue gas treatment apparatus to reduce a usage amount of high-temperature resistance material and further to reduce a thermal elongation of piping. In a thermal power plant including a 2 pass-type boiler having a furnace for burning fuel, a rear heat recovery area for recovering heat from combustion gas exhausted from the furnace, steam turbines are arranged near the rear heat recovery area.
