Riken Keiki Co’s OHC-800 (photo), a relatively new type of calorimeter, uses optical and sonic sensors to provide real-time monitoring with high accuracy. The instrument’s use in optimizing turbine and boiler air/fuel ratios make it of interest to O&M personnel at gas-turbine-based simple- and combined-cycle plants. Recall that competitor gas chromatographs provide highly accurate analyses

New purge procedure allows faster start of gas-line maintenance Challenge. CPV Valley Energy Center’s procedure for depressurization and purge of its fuel-gas system for inspection and maintenance required multiple movements of equipment (nitrogen trailers and hook-ups). Plant’s goal was having a procedure that didn’t require the movement of equipment and one conducive to faster purging.

Electronic log enables tighter control of boiler chemistry Challenge. The need for proper control of boiler chemistry is well known. An important part of any operator’s shift involves monitoring of boiler chemistry parameters and taking action to ensure they are maintained within posted specifications. The actions in real time help assure long-term integrity of boiler

Permanent monitoring system cuts time, cost of vibration analysis Background. Klamath Energy’s mechanical-draft counterflow cooling tower was built by Balcke-Dürr in 2000 without vibration probes installed on its gearboxes. The CT is of fiberglass-reinforced polyester (FRP) construction with eight cells, each 48 ft wide × 48 ft long. The tower’s fans are driven by 200-hp,

Single-permissive remote start, automated fuel equalizing Challenge. Rolling Hills recently updated its run profile from a 30-min start window to five minutes. Like many other plants with a 5-min window, a remote start program was implemented. The challenge that Rolling Hills faced was to simplify the old startup sequence so an operator could bring units

An owner/operator presenting on aqueous-ammonia (NH3) storage tank inspections at the CCUG2020 Week Four session said that according to the governing standard, API510, a “fitness for service” assessment should be conducted every 10 years (or half the remaining life calculated during the last inspection) for pressure tanks. The method results in a calculated remaining life,

EPRI Technical Executive Sam Korellis opened the CCUG2020 Week Four agenda with a review of EPRI’s cooling-tower (CT) fan-motor-drive and gearbox field evaluation program and its implications for CTs serving more than 800 units at about 300 powerplants. Many CTs are equipped with multiple fans which start and stop depending on load and ambient temperature.
