Abstract (en)
[origin: EP2325560A1] Provided is a reheat boiler in which the imbalance in temperature distribution of the temperature of the combustion gas at the outlet of a reheat furnace is reduced by changing the gas flow pattern in the reheat burner. A reheat boiler (10A) includes a main boiler (106) configured such that main combustion gas generated in combustion in a burner (101) flows from a furnace (102) through a superheater (104) and evaporator tubes (105), a reheat furnace (108) that is disposed on the downstream of the evaporator tubes (105) and produces reheat combustion gas by combustion in a reheat burner (107), and a reheater (109) disposed above the reheat furnace (108). A closing plate (130), serving as a drift preventing portion, is provided at a reheat furnace outlet (120) that connects the reheat furnace (108) and the reheater (109) to form a flow path for the combustion gas and the reheat combustion gas so as to narrow the cross-sectional area of the flow path for the combustion gas.
