Generation of Steam from a Waste Heat Boiler
야금법의 용광로나 화석연료기관의 작동에서 생성되는 배기가스들은 고온상태로 배출된다. 이때 이러한 고온상태의 배기가스들을 이용하여 가열하는 기관을 Waste Heat Boiler라 한다. 배기가스를 그냥 배출시킬 경우 상당한 열이 낭비되므로 이를 재활용하여

Rankine cycle
In a real Rankine cycle, the compression by the pump and the expansion in the turbine are not isentropic. In other words, these processes are non-reversible and entropy is increased during the two processes. This somewhat increases the power required by the pump and decreases the power generated by the turbine.
In particular the efficiency of the steam turbine will be limited

Downtown L.A. Noon on a hot summer day. On an EXTREME LONG LENS the
lunchtime crowd stacks up into a wall of humanity. In SLOW MOTION they
move in herds among the glittering rows of cars jammed bumper to bumper.
Heat ripples distort the torrent of faces. The image is surreal,
dreamy... and like a dream it begins very slowly to
dissolve to:

Science fiction plucks from within us our deepest fears and hopes then shows them to us in rough disguise: The monster and the rocket.
