How Power Plants Can Save Valuable Time, Resources

Posted by Sentry Equipment on 9/23/15 10:00 AM

More and more, power plants must cycle to fill in gaps caused by disruptive power generation and in response to the need to bid on and dispatch electricity at certain times in the competitive marketplace. This means plants cycle based on demand and market prices for their energy production.

Ways ISOLOK Samplers Help Treatment Plants Automate Messy Job

Posted by Sentry Equipment on 9/9/15 10:00 AM

A wastewater treatment plant treats sewage or industrial wastewater before discharging it. Typically, the plant will remove solid materials in the primary treatment. The remaining liquids then are treated for dissolved and suspended organic material in secondary treatment, and finally, disinfection treatment kills disease-causing microorganisms.

Customer Reduces Maintenance Time And Cost On Power Plant Sample Panels

Posted by Sentry Equipment on 7/22/15 10:00 AM

A North American coal-fired electrical power station was implementing a strict maintenance and calibration procedure for their new steam and water sample panels. This procedure included weekly removal, cleaning, calibration and reinstalling of 22 conductivity probes – which are used to find the concentration of total dissolved solids, or TDS, in a sample of water.

Protect Power Plant Operators & Water Chemistry Instruments From Harm

Posted by Sentry Equipment on 6/24/15 10:00 AM

Imagine this scenario: A power plant’s primary coolant pump loses power and is no longer providing coolant to the primary coolers. A steam sample in excess of 250°F continues to flow. In the chemistry lab, an operator works at a computer. A pipe hisses as the room begins to fill with dangerous steam. At the end of the sample tubes are costly analyzers about to be destroyed. The operator realizes what's happening and hurries to shut down the sample lines. The analyzers suffer minor damage but the operator is able to repair them. But, what about next time?

New Magnetic Trap Alleviates Combined Cycle Power Plant’s Iron Issue

Posted by Sentry Equipment on 5/27/15 10:00 AM

A combined cycle power plant uses both a gas and a steam turbine together to produce up to 50 percent more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power.

How to Select the Right Sample Cooler for Your Power Plant

Posted by Sentry Equipment on 4/22/15 10:00 AM

A sample cooler for steam & water sampling within a power plant is used to cool a sample from a process stream and is simply a small shell and coil heat exchanger. The sample to be cooled flows through the tube side of the cooler, and the cooling fluid, usually water, flows through the shell side. The cooled sample then is taken to a laboratory for analysis or, in some cases, piped to in-line process instrumentation for continuous monitoring of certain properties such as conductivity, pH or chemical constituents.

Today’s Trends In Power Plant Water Chemistry Programs

Posted by Sentry Equipment on 3/25/15 10:00 AM

There certainly are many challenges associated with maintaining an aging power plant’s water chemistry program and ensuring the safety and reliability of plant assets and operators through timely, accurate analysis of water and steam. The program will need to manage and conquer corrosion and scaling issues, standardize methods of sampling water and steam for analysis, and ensure compliance with EPA regulations for waste water disposal.
