Steam Temperature Control | Control Notes

I would like to ask you if it’s possible to control steam temperature using characteristic curve. In the plant where I worked, the main and re-heat steam temperature control loop is cascade without feedforward demand. At first, the main and re-heat steam temperatures swinged and it affected MW and steam pressure.

Boiler Drum Level Control | Control Notes

A very common control problem, and one used in many examples elsewhere, is that of controlling the level in a boiler drum. Many industrial plants have boilers for generating process steam, and of course boilers are central to thermal power generation. The boiler drum is where water and steam are separated.
