This valve is used to regulate the boiler drum to ensure that there is always enough feedwater in the boiler to create steam. The boiler feedwater control valve must have an equal-percentage characteristic to compensate for the difference between the characteristic of the boiler feedwater pump and the boiler plant (series 8C, 6H, 350, 380).

Steam Temperature Control | Control Notes

Steam temperature is one of the most challenging control loops in a power plant boiler because it is highly nonlinear and has a long dead time and time lag. Adding to the challenge, steam temperature is affected by boiler load, rate of change of boiler load, air flow rate, the combination of burners in service, and the amount of soot on the
