Temperature measurement in boilers - coal-fired

In a coal-fired power plant, the boilers generate thermal energy by burning pulverized coal. Accurate temperature control is very important to maintain a safe and stable process. Two Pt100 sensors are used to make a redundant temperature measurement.

Proper Boiler Feed Water Temperature Management |

Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.

Automatic Boiler Water Temperature Control

Direct Control of the Boiler Water Temperature. The simplest but usually least effective method is to control the boiler water temperature setting. Unfortunately, the lowest temperature possible under this method is 140° (160°-165°) - which is far above the lowest temperature

Temperature measurement in boilers - coal-fired

In a coal-fired power plant, the boilers generate thermal energy by burning pulverized coal. Accurate temperature control is very important to maintain a safe and stable process. Two Pt100 sensors are used to make a redundant temperature measurement.
