    • The waste heat steam generator employs two parallel channels for receiving flows of exhaust gas from a gas turbine. In one channel, the exhaust gas flow is heated by a supplemental burner to a temperature less than 900.degree. C while the flow of exhaust gas in the second channel is heated to a temperature above 900.degree. C. The amount of fuel supplied to each burner is controlled by various control means responsive to the temperature within the steam generator or the temperature of the live steam or by the pressure of the live steam. A distribution means is provided at the entrance to the channel in which the exhaust gas is heated to a temperature above 900.degree. C so as to control the flow therein. The steam generator can be easily adapted to partial load operation by regulating the amount of fuel to the supplemental burners.
    • 废热蒸汽发生器采用两个平行通道来接收来自燃气轮机的废气流。 在一个通道中,废气流被补充燃烧器加热到低于900℃的温度,同时将第二通道中的废气流加热到高于900℃的温度。供应给每个燃烧器的燃料量 由响应于蒸汽发生器内的温度或活蒸汽的温度或通过活蒸汽的压力的各种控制装置控制。 在通道的入口处设置分配装置,在该入口处,废气被加热到高于900℃的温度,以便控制其中的流动。 通过调节补充燃烧器的燃料量,蒸汽发生器可以容易地适应于部分负荷运行。
