Abstract: The boiler (1) according to an aspect of the present invention is provided with a boiler main body (3) and a steel support frame (5) that suspends and supports the boiler main body (3). The boiler main body (3) is provided with: a furnace wall (11) composed of water pipes (15) and plate-like fins (16) arranged in an alternating manner; an internal element (4) housed inside the furnace wall (11); and a buffering mechanism (20) configured to attenuate vibration energy when relative displacement, of the internal element (4) with respect to the furnace wall (11), occurs that exceeds a predetermined value. The buffering mechanism (20) is disposed between the furnace wall (11) and the internal element (4) in the main vibration direction of the internal element (4), and the load on the buffering mechanism (20) caused by interference is transmitted to the fins (16).

Abstract: A steam generator apparatus for generating steam from a feedwater inlet stream including impurities is disclosed. The apparatus includes a tubing circuit in communication with an inlet for receiving the feedwater stream, the tubing circuit having a substantially unrifled bore defined by a metal wall, and a heat source operable to deliver a heat flux to the feedwater stream through the metal wall of the tubing circuit, the heat flux being operable to cause evaporation of feedwater within the tubing circuit and to produce an outlet stream at an outlet of the tubing circuit, the outlet stream includes a steam portion and liquid phase portion, the steam portion being greater than about 80% of the outlet stream by mass, the steam portion providing sufficient cooling of the metal wall to maintain a wall temperature at less than a threshold temperature associated with safe operation of the steam generator apparatus.
