Steam Temperature Control
Reduce tube leaks by addressing thermal stress on your boilers and HRSGs.
Reduce tube leaks by addressing thermal stress on your boilers and HRSGs.
Increased cycling places additional mechanical stresses on boilers and heat recovery steam generators (HRSGs), particularly influenced by underperforming superheat and reheat loops. The suboptimal performance of these important loops can increase the frequency of tube leaks.
By working with Emerson, you can optimize this critical control loop in your plant’s systems, mitigating the effects of cycling and improving availability of your units.
Power plants have traditionally used direct wire thermocouples for temperature. Since they provide no indication they are drifting or failing , which all thermocouples do, from wire thinning, sensor degradation, or corrosion; relying on them for accurate measurement when a plant is cycling can be problematic.
Emerson's power industry experts can help you ensure your thermocouples are performing by adding temperature transmitters. By doing this, you’ll know in advance if your temperature measurement is compromised before exceeding any thermal limits in your plant.
Traditional PID temperature control, including feedforward, does not control temperature as tightly as required when a plant is consistently cycled.
By working with Emerson, you can install advanced process control (APC) on critical temperature control loops which anticipates how a plant will react based as it moved and provides very tight attemperation control, even in the most demanding cycling regimes.
Damaging thermal excursions can occur because of imprecise control of spray valves and improper maintenance of attemperators.
Emerson's network of valve experts can help you reevaluate your attemperator loops for performance and durability.
