Decompression boiler, binary power generation system including the decompression boiler, and incineration facility including the binary power generation system

摘要

To provide a pressure-reduced boiler, a binary power generation system including the pressure-reduced boiler, and an incineration facility, capable of preventing accumulation blockage in a flue tube due to soot dust included in a combustion exhaust gas, and inhibition of heat transfer in accompany therewith, improving a heat transfer property by improving circulation force of boiler water, and being miniaturized.SOLUTION: In a pressure-reduced boiler 6 in which a refrigerant of a binary power generation system 8 is heated by heat recovered from a combustion gas G including soot dust from an incinerator 1, a plurality of smoke pipes 6 in a can body are disposed in a vertical direction.SELECTED DRAWING: Figure 1
