Abstract

A heat exchanger apparatus for receiving water from d steam drum (1) and providing steam and heated unevaporated liquid water to the steam drum includes a first evaporator (EVAP-I ) 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 (I I). Both evaporators can output heated fluid to the steam drum via a combined evaporator output conduit (1 3). Each first evaporator passageway (1 4) only makes a single pass through a gas duct:(15) having a heated gas flow (7) passing . there through while each second evaporator passageways (24) can make one or more passes through the gas duct for tansferring 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).
