--- Depend on the requirements of bed height or bed temperature for different loads, the boiler combustion should be stabilized by adjusting the boiler feeding amount, and the steam pressure fluctuation must be controlled to be within 5.3MPa ±0.05Mpa. （furnace medium pessure maintain within 3.82MPa ±0.05MPa)
--- The adjusting of feedwater amount plays a supporting role on the controlling of the steam pressure, and the drum water level should be maintained to be within the allowable scope.
