Abstract: A heat exchanger apparatus for receiving water from a steam drum (1) and providing steam and heated unevaporated liquid water to the steam drum includes a first evaporator (EVAP-1) and a second evaporator (EVAP-2). The first evaporator can receive water from a steam drum via a first feed conduit (9) and the second evaporator can receive water from a second feed conduit (11). Both evaporators can output heated fluid to the steam drum via a combined evaporator output conduit (13). Each first evaporator passageway (14) only makes a single pass through a gas duct (15) having a heated gas flow (7) passing therethrough while each second evaporator passageways (24) can make one or more passes through the gas duct for transferring heat from the gas to the fluid within the evaporators. A portion of the first feed conduit can also have a pre-specified volume a pre-specified height below the first inlet (10).

Abstract: An auxiliary steam supply system in a solar power plant includes a solar receiver having a superheater section, a turbine, a steam circuit, a thermal energy storage arrangement and an auxiliary steam circuit. The thermal energy storage arrangement, including a thermal energy storage medium, is configured for the steam circuit to receive a portion of the steam to heat the thermal energy storage medium. The thermal energy storage arrangement may receive the steam from any location across the superheater section. Moreover, the auxiliary steam circuit generating auxiliary steam flow, which thermally communicates with the thermal energy storage arrangement to be heated, is introduced to any location across the superheater section. Capacity of the thermal energy storage arrangement may be relatively small as compared to the solar receiver and may be compact for placement on top of a tower.
