Power plant technology : Temperature measurement technology for power generation in power plants
Power plants are required to handle tremendous forces to supply us all with power. Demand for higher efficiency and lower carbon dioxide emissions paired with new operating parameters requires new approaches for obtaining measured values. RÖSSEL-Messtechnik is ahead of the curve with suitable measurement technology and solution-driven consulting! We have been a leading partner for temperature measurement technology in the power plant industry for several decades. Working in close cooperation with plant operators and manufacturers, we have completed a large number of projects and are always exploring new pioneering ways to record measured values.
When it comes to power plant technology, we don’t just rely on our extensive expertise, but also our entire range of measurement technology products. These include high-voltage resistant and oil-tight sensors, high-temperature thermocouples and sensors for potentially explosive atmospheres.
RÖSSEL-Messtechnik also products technology including ignition cables and ignition electrodes for igniting gas flows under extreme conditions. Whether your require standard components or user-specific designs – we offer solutions for all types of power plants.
In order to monitor wide-body equipment in open pit mines, the temperatures of components susceptible to overheating need to be controlled under extreme conditions, particularly when exposed to combustible dusts. Temperature sensors are used to monitor storage rooms and for conveying and crushing processes when storing and processing coal or waste. Resistance thermometers approved for hazardous areas are primarily used.
High precision temperature measurement for fossil fuel combustion increases the effectiveness of the process while minimizing carbon dioxide emissions. The sensors are characterized by their high accuracy, ability to be calibrated during the process and their long service life. Only thermocouples are used for this purpose.
Gas turbines are ignited by a high energy electrical discharge that triggers a spark. Along with temperature sensors, RÖSSEL-Messtechnik also supplies the power plant industry with special ignition cables and ignition electrodes for igniting gas flows under extreme conditions.
The process of converting into a high voltage and back releases heat that needs to be monitored in the oil-cooled transformer systems. As a result, measuring generator temperatures requires temperature sensors and accessories that are both high-voltage resistant and oil-tight. Notch resistance thermometers are also used in the generator windings to offer protect against overheating and short circuits resulting from material changes and wear sustained by the bearings.
In industrial areas or large cities, steam turbines are often installed downstream of gas turbines to use any residual heat for district heating systems. Sensors with special weld-in pockets are ideal for measuring temperatures in the pressure tanks. Surface sensors are also used to check the metallic outer shell for any perforations caused by steam pressure.
In order to heat water in the boiler, the boiler principle typically involves using separate circuits, usually a hot gas circuit and a water circuit. Due to the particulate and high flow rates, the metallic burner tubes in the burner tube (gas circuit) become thinner over their service life. This requires monitoring by special thermocouples. Sheathed thermocouples that exhibit particular resistance and flexibility thanks to their special Inconel-600 sheath are often used to protect pipes and tanks (boilers) against overheating during start-up.
The surfaces of the combustion chambers in power plants require cooling. In order to use the waste heat produced in a constructive manner, a reading first needs to be obtained for the temperature of the media. This is where resistance thermometers come in.
Saving energy with red-hot ideas
Gas-fired power plants are becoming increasingly alongside solar and biogas power plants in the energy revolution. Operating the latest generations of gas turbines requires not only high-performance temperature sensors, but also suitable burner and ignition technology. Backed by its vast expertise in materials technology, development and manufacturing, RÖSSEL-Messtechnik has partnered up with one of the leading turbine manufacturers in Europe and Bureau Veritas to design an ignition cable that can withstand the highest loads produced by the latest generations of gas turbines.
