Abstract
A steam generator includes a substantially horizontal gas conduit () to guide a heating gas flow () and an evaporator unit positioned at least partially in the horizontal gas conduit for transferring heat from the heating gas to a flow medium which flows through the evaporator unit. The heat transfer section of the evaporator unit of the steam generator is bottom fed, which means that the inlet conduit is arranged at a lower region of the heat transfer section. The outlet conduit is arranged at an upper region. The inlet conduit allows an once through operation of the evaporator section which is necessary to enable operation under supercritical circumstances. The evaporator unit includes at least two evaporator stages () which are arranged in a cascade. Each evaporator stage includes a heat transfer section () and a separator (). The presence of the separators () subdivides the evaporator unit into evaporator stages ().
