Regulate Pressure in Drum Boiler - MATLAB & Simulink

In this drum-boiler model, the control problem is to regulate boiler pressure in the face of random heat fluctuations from the furnace by adjusting the feed water flow rate and the nominal heat applied. For this example, 95% of the random heat fluctuations are less than 50% of the nominal heating value, which is not unusual for a furnace-fired

Real Time Monitoring and Controlling Of Boiler Drum …

The boiler drum level must be controlled to the limits specified by the boiler manufacturer. If the boiler drum level does not stay within these limits, there may be water carryover. If the level exceeds the limits, boiler water carryover into the super-heater or the turbine may cause damage resulting in extensive maintenance costs or outages of either the turbine or the boiler.

1/5/2017 · Boiler drum or steam drum is an external storage tank in a natural circulation boiler fixed above the evaporator. The two-phase mixture is separated into saturated steam inside the drum. This separated steam flows out from the drum and remaining water mixes with the feed water to recirculate.
