Boiler Control System Engineering introduction Boilers are a key power source for electrical generation in the United States and around the world and for providing heat in process industries and buildings. Regardless of the capacity or fuel, there are certain fundamental control systems required for boiler control. Large utility systems are more complex due to

Get a QuoteThe electric boiler as object controlloed has the characteristics of nonlinear, time-varying and large lag, and the temperature control system of it has been a challenge. In order to improve the control performance, a novel temperature control system was designed. The system consists of temperature controller, temperature acquisition, temperature display, serial communication, and warning circuit.

Get a QuoteUnless your boiler knows what the actual temperature outside is, it will operate as if it's the coldest day of the yeareven if it isn't. Enter outdoor reset! When equipped with this discrete device, the boiler control reads the temperature outside and knows how to adjust the operation of the heating system accordingly.
Get a QuoteThe boiler temperature control system mainly includes the adjustment of the superheated steam and the reheat steam temperature. The superheated steam temperature is the highest temperature in the boiler soda system. The stability of the steam temperature is very important for the safe and economical operation of the unit.
Get a QuoteSteam 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
Get a QuoteIt's important to remember that the thermostat is reacting to the temperature in the room, not in the radiators or the boiler. If you set your thermostat to 18 °C on a hot day, there's a good chance the heating won't come on at all, as the sun is doing all the work.

Get a QuoteOnce a boiler starts to go over 212°F, you can face serious problems. Watch out for overheating. If you notice that your boiler's temperature is going higher than the above settings, you have a major problem. If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking.
