1.When the load is increased/decreased, the boiler combustion shall be adjusted in order to reach the requirement of external load as fast as possible.

2.When the steam temperature is changing, the attemperation water volume shall be adjusted accordingly in order to ensure that the steam temperature changes in the normal range.

3.When the main steam temperature change is bigger and it is hard to adjust, the combustion condition of the boiler itself shall be stabilized firstly and the steam turbine shall be contacted for stabilizing the external load and stabilizing the pressure. When the pressure is stabilized, the adjusting range of attemperation water shall be adjusted as possible, then the main steam temperature will be stabilized gradually.( The stabilizing pressure is the precondition for stabilizing temperature, therefore when the pressure is changing, the attemperation water volume shall be increased/decreased in advance with the increase/decrease of the pressure in order to keep the temperature in stable status).

4.When the combustion condition is strengthened, it is required to keep close watch on the changing of the main steam temperature and to adjust the attemperature water.

5.When the steam pressure changes but the adjustment of combustion condition can not meet the requirement, it is required to contact the steam turbine to increase/decrease the load, in order to maintain the stabilization of pressure.
