A direct evaporator apparatus (10) for use in an organic Rankine cycle energy recovery system, comprising: (a) a housing (44) comprising a heat source gas inlet (36), and a heat source gas outlet (38), said housing defining a heat source gas flow path (46) from said inlet to said outlet; and (b) a heat exchange tube disposed entirely within said heat source flow path, said heat exchange tube (18) being configured to accommodate an organic Rankine cycle working fluid, said heat exchange tube comprising a working fluid inlet (40) and a working fluid outlet (42), said heat exchange tube defining three zones, a first zone (20) adjacent to said heat source gas outlet, a second zone (22) adjacent to said heat source gas inlet, and a third zone (24) disposed between said first zone and said second zone, said working fluid inlet being in direct fluid communication with said first zone, and said working fluid outlet being in direct fluid communication with said third zone; wherein said first zone is not in direct fluid communication with said third zone. An organic Rankine cycle energy recovery system and a method of energy recovery are also provided. |
