steam temperature control of boiler - stundenzettel

To control the steam temperature of the boiler heat transfer rate in boiler is controlled by manipulating fuel flow rate. The main steam temperature change is mainly caused by the fuel flow changes and heat transfer rate between various elements of boiler. In steady conditions, the heat transfer rate can be considered stable.

Temperature of steam versus water in a boil

2009-10-17 · How much of a difference is there in the temperature of steam in a boiler compared to the temperature of the water? Why I'm asking is to find out how critical it is that a temperature probe be immersed in the water in a boiler. I'm thinking that the temperature level can change, so does the probe have to go really low, or is

Steam Temperature Control Control Not

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

US4887431A - Superheater outlet steam temperature

A method and apparatus for controlling superheater outlet temperature of a steam generator utilizes a feed-forward control signal to control a spray attemperator. The feed-forward control signal is developed as a difference between a selected flow rate for steam required by a turbine operated by the steam generator, and a measured flow rate of steam from a steam drum above the steam generator.
