Treated water drying device and boiler system including the same

A boiler system comprising:

• a boiler;
• a desulfurization device for desulfurizing an exhaust gas discharged from the boiler by bringing the exhaust gas into contact with an absorption liquid;
• and
• a treated water drying device for vaporizing treated water by heat of a combustion gas,
• wherein the treated water drying device includes:
• a housing having at least a pair of opposed, parallel, substantially vertical sidewalls, one of the pair of substantially vertical sidewalls defining a side surface of the housing;
• a combustion gas supply port in an upper portion of the housing for supplying the combustion gas to the housing;
• a treated water supply portion in the upper portion of the housing for supplying the treated water into the housing;
• an exhaust port for discharging a water-containing gas including the treated water that has been supplied to the housing and vaporized to an outside of the housing,
• the exhaust port is formed on the side surface of the housing and opening in a direction crossing a vertical direction,
• the housing has a bottom connected to a bottom surface of the exhaust port and the housing bottom including an inclined portion and being formed as a solid, continuous, closed concave member extending from the other of the pair of vertical sidewalls, from a vertical position substantially above the bottom surface of the exhaust port along a smoothly curved concave path to the point that the housing bottom is connected to the bottom surface of the exhaust port,
• wherein the combustion gas includes the exhaust gas discharged from the boiler, and
• wherein the treated water includes the absorption liquid that has contacted the exhaust gas and discharged from the desulfurization device.
