Hello Experts,
I have a question regarding the operation of a steam boiler.
if the load is increased on the turbine generator set of a steam power plant, i learned that the fuel injection to the boiler has to be increased to serve the additional load. so my question is, do we also have to increase the feed water flow to the boiler? I have different answers from different people.
one of those was the water supply to the boiler is always maintained constant at constant pressure, the only difference we see is that the amount of steam generated in the boiler varies with the fuel input and the rest of the water keep circulating from the boiler to the feedwater tank.
may I know if how exactly does it work in the real scenario? is the pressure before and after the boiler is same? also is the mass flow of water to the boiler is always constant?
how can we estimate the time taken to ramp up the boiler from one load to another?
thank you in advance
yours sincerely
