A flue gas desulfurizer having an absorption tower for bringing untreated flue gas into gas-liquid contact with an absorbent slurry, wherein there is provided heat recovery means for recovering heat from the flue gas passing through the flue gas inlet section of the absorption tower prior to gas-liquid contact, and to boiler equipment including heat release means for releasing the recovered heat to heat utilization equipment. This invention also relates to thermal electric power generation equipment including extraction feedwater heaters for heating boiler feedwater with steam from steam turbines, a flue gas desulfurizer using an absorbent slurry, and means for recovering heat from the flue gas passing through the flue gas desulfurizer and/or the absorbent slurry within the flue gas desulfurizer, whereby boiler feedwater is preheated by the recovered heat and then introduced into the extraction feedwater heaters.

A cooling system typically incorporated in an outdoor rest facility has a substantially vertical tower extending vertically through the roof of the outdoor rest facility and having an air passageway defined vertically therein. The air passageway has an air inlet port defined in an upper end thereof for introducing air into the air passageway. A water ejector is disposed in the upper end of the air passageway for ejecting a shower of water downwardly through the air passageway from the upper end of the air passageway. A water retriever is disposed downwardly of and spaced from the tower, for retrieving the shower of water falling through the air passageway. An air outlet port is defined between an open lower end of the tower and the water retriever, for discharging air cooled by the shower of water out of the air passageway.
