Various technologies pertaining to tuning composition of a fluid mixture in a supercritical Brayton cycle power generation system are described herein. Compounds, such as Alkanes, are selectively added or removed from an operating fluid of the supercritical Brayton cycle power generation system to cause the critical temperature of the fluid to move up or down, depending upon environmental conditions. As efficiency of the supercritical Brayton cycle power generation system is substantially optimized when heat is rejected near the critical temperature of the fluid, dynamically modifying the critical temperature of the fluid based upon sensed environmental conditions improves efficiency of such a system.

Disclosed are a test loop for simulating a steam generator with or without an axial economizer and a test method thereof. The loop includes a cooling water loop, a water supply loop, a recirculated water loop and a power supply. The cooling water loop is used for condensing and cooling wet steam and providing the wet steam to the water supply loop and the recirculated water loop. The water supply loop is used for providing cold-state water supply for a test device, the recirculated water loop is used for reheating cooled water to be saturated and providing the water to the test device. The power supply is used for supplying power to heating equipment and an electric heater in the test device. The present disclosure provides a test method of the loop. Simulation tests can be carried out on a steam generator with or without an axial economizer.

Provided is a boiler configured to perform heating by a heat generation section provided with heat generation bodies in a container and capable of properly charging a circulation path including, as part thereof, the inside of the container with required gas. A boiler includes: heat generation bodies; a container configured such that the heat generation bodies are provided inside and configured chargeable with gas with higher specific heat than that of air; and a circulation path including, as part thereof, the inside of the container, the circulation path being a path in which gas circulates. When the charging process of charging the circulation path with the gas is performed, a circulation amount and a gas concentration in the circulation path are monitored.

A pump uses the steam hammer effect to pump water from a reservoir into a control volume. Steam is injected into a water conduit extending between a liquid water reservoir and the control volume forms a liquid steam interface. Steam within the conduit condenses on the interface creating a region of partial vacuum. Water accelerates into the region of partial vacuum and is vented into the control volume, flow being controlled by a valve.
