Power plants that frequently cycle or have sliding pressures often require technicians to adjust the variable pressure-reducing element manually. However, properly installing an automated flow controller helps alleviate this stress by automating sample flow.

Faced with budgetary and personnel constraints, many plant managers must make difficult choices to ensure their steam-water analysis system can provide the critical data they need to protect their equipment. Yet, improperly installed or retrofitted SWAS can have far-reaching maintenance and downtime effects, leaving you without necessary visibility.

The thermal management of sample coolers is critical to the proper function of a steam and water analysis system (SWAS). Extreme temperatures can lead to erratic or unreliable data, equipment damage and unscheduled downtime. As the EPRI standard states, the goal of a sample system is to “transport and condition a sample without altering the characteristics of interest. The system parameters which need to be controlled are velocity, pressure and temperature.”

By analyzing and monitoring chemical properties of steam and water, a steam and water analysis system ensures you are protecting the generation assets in your plant. Maintaining this system is critical to ensuring accurate results from grab sample and sample panel data. Here’s what you need to know about implementing a regular maintenance schedule for your utility’s SWAS.

Chemical analysis of water and steam samples in utility plants requires precise control of flow and pressure. A common element of the steam and water sampling system is a pressure reducing valve to control the pressure of the sample. However, using an incorrect valve can not only damage plant and sampling equipment, but possibly injure operators. That’s why it’s essential to match plant applications with the correct pressure reducing valves.

The goal of a steam and water analysis system (SWAS) in power generation is to properly condition the sample so that it is representative of the process. Secondary sample cooling provides a way to eliminate measurement uncertainty issues by removing the variable of temperature from the measurement. Secondary cooling also provides a temperature “cushion” when primary cooling systems are undersized or underperforming.
