摘要：
The control of the actual liquid level in a boiler is accomplished by using the flow rate of the fuel to the combustion system associated with the boiler to generate a signal which is utilized to bias a control signal generated in response to steam flow rate and the output from a conventional level controller in such a manner that swell and shrink caused by changes in fuel flow rate is compensated for and the desired liquid level is maintained in the boiler.
