Reducing the variables in the level measurement equation to improve the performance of the boiler nozzle.

The large-scale integration of renewable technologies in the energy mix and in mitigating climate change has fundamentally changed the daily operation of fossil fuel plants. As a result, operators prefer a system that offers improved performance when managing the steam nozzle level during start-up, basic load, cycle and duct burner operations, as well as during shutdown.

Although common in steam pipe level control, most traditional technologies are not inherently suitable for the wide range of process conditions experienced in a steam pipe over the course of a day.

Differential pressure (DP) depends on an excessive number of variables to infer the level, which creates several paths for errors and points of failure. In addition, operators may be blinded during the start-up sequence to allow the recovery of condensate sections. Conductivity technology greatly simplifies measurement, so operators have limited visibility to the actual level in the steam nozzle. Both scenarios can have a negative impact on critical plant performance metrics.

Magnetrol’s model 706 guided wave radar system is a stand-alone platform designed to optimize performance in a wide range of operational scenarios to ensure availability.

The Eclipse® Model 706 improves performance by reducing hardware complexity, removing technologies with known and expensive periodic maintenance requirements and eliminating instrument-induced errors.

One technology for all applications:
• Steam Drums (HP, LP, IP);
• Feed Water Heaters;
• Hotwell condenser;
• Deaerator (DA);
• Gas Conditioning Skids;
• Cooling Tower Basins;
• Purge Tank;
• Lubrication Oil Reservoirs;
• Demineralizer and Condensate Overflow Tanks;
• Water Forbay recirculation;
• Raw Water Intake Level;
• Inventory and Storage of Chemicals;
• Deposit Level.

Traditional steam pipe level instrumentation falls into two categories – Pressure and Conductivity. Those dependent on pressure require periodic calibration and external compensation to infer the level, while conductivity offers limited resolution. Both are proven to have a higher cost of ownership over the product’s life cycle as they are susceptible to drift, build-up and mechanical wear.
