PROBLEM TO BE SOLVED: To inhibit the unbalance of a fluid temperature at a furnace outlet of a boiler by interchanging fluids in heat exchanger tubes passing through the water walls of a furnace between the right and left walls or the front and rear walls via the intermediate of the furnace.;SOLUTION: This once-through boiler includes the furnace, the heat transfer tubes and a burner, wherein four furnace lower part outlet headers 21 and four furnace upper part inlet headers 28 are provided at the intermediate 10 of the furnace, and two fluid mixture means 23 and two fluid distribution means 26 via communication tubes 24 are provided between both headers 21, 28. The two fluid mixture means 23 mix right-and-left-side fluids collected from the furnace lower part outlet headers 21 disposed on the right and left sides of the furnace, respectively, and deliver the mixed fluids through the communication tubes 24 to the fluid distribution means 26, respectively. The two fluid distribution means 26 form fluid flow paths for the four furnace upper part inlet headers 28 to interchange the fluids in the right and left heat transfer tubes of the furnace between the lower part and the upper part of the furnace.;COPYRIGHT: (C)2012,JPO&INPIT
