    摘要: An apparatus and method for controlling a steam generator operating under rapidly varying load conditions. The method measures steam flow and pressure and combines the measurements with a signal that is proportional to the rate of change of steam flow and utilizes the resulting signal to control the fuel and air flow to the steam generator.
