The heated tank has a heat exchanger spaced from the bottom of the car to define a dead space to insulate the heat exchanger from the bottom. The heat exchanger extends longitudinally and transversely across the entire bottom of the car to provide a large heating transfer surface to the lading supported by the exchanger. A portion of the exchanger encompasses a discharge valve of the tank car to provide heat transfer to the valve during unloading. The heat exchanger slopes toward the discharge valve to facilitate total removal of the lading. An inlet and an outlet associated with the heat exchanger are disposed adjacent the discharge valve for additional transfer of heat to the discharge valve. |
