Not sure that this is accurate, isn't the "work" in a boiler done by the phase transition to steam and the associated increase in pressure? Unless you're referring to a particular design of solar energy production.
- ndonnellan 13y agoThere is no associated increase in pressure in the boiler typically. In fact, there's usually a pressure drop. The high pressure is created in the feedwater pumps for a steam system. The boiler converts liquid at high pressure to steam at high pressure. The steam volume then expands to perform work in a turbine. A salt-plant would probably use steam near 100bar and expand it through the turbine to below 1 bar (sub-ambient) such that the saturation temperature is as close to ambient temperature as possible. There is a significant amount of work done at the last stages of the turbine (when going from +1bar -> 0.1 bar) so increasing the ambient temperature can have a noticeable on total cycle efficiency.
