Recent release: Technical guidance documents on powerplant chemistry

The Power Plant Chemistry (PPC) working group of IAPWS (pronounced eye-apps), the International Association for the Properties of Water and Steam, released two technical guidance documents (TGDs) of value to powerplant owner/operators at its annual meeting in Dresden, Germany, Sept 11-16, 2016:

  • “Application of Film-Forming Amines in Fossil, Combined Cycle, and Biomass Plants.”

  • “HRSG High-Pressure Evaporator Sampling for Internal Deposit Identification and for Determining the Need to Chemical Clean.”

Both are available free-of-charge on the organization’s website, where you’ll likely identify several more useful TGDs.

By way of background, the primary purpose of the annual IAPWS meetings is to connect researchers and scientists with the engineers who use their information. The free-flowing exchange provides researchers with guidance on topical industry problems and the engineers with the latest research results. Areas of technology addressed by IAPWS of greatest interest to electricity producers are powerplant chemistry, power cycles with CO2 capture and storage, and combined heat and power systems—including district heating.

The PPC working group discussed development of new TGDs (one on demineralized water) and several white papers—including corrosion-product sampling for plants on flexible operation and minimization of air in-leakage into steam/water cycles. The group also identified a significant step forward in understanding the behavior of aluminum in steam-cycle circuits.

The meeting just concluded attracted 90 scientists and engineers from 18 countries. This year, the organization welcomed New Zealand as a full member and formally approved Egypt as an associate member. The next meeting will be in Kyoto, Japan, Aug 27-Sept 1, 2017. Executive Secretary Dr R Barry Dooley reminds that you do not have to be a citizen or resident of a member country (see list on website) to participate in IAPWS activities.

Siemens update

Panda Power Funds and the OEM commissioned two H-class combined cycles in Pennsylvania this fall. The Liberty and Patriot projects each are rated 829 MW and consist of two single-shaft power blocks (SGT6-8000H gas turbines, SST6-5000 steam turbines, SGen6-2000H generators). A complementary service agreement includes parts, inspections, scheduled service/maintenance, and Siemens’ Power Diagnostics™ (remote monitoring and diagnostics).

Siemens ships its first F-class gas turbine for Iran’s Bandar Abbas project—simple cycle today, combined cycle in the future. The two SGT5-4000F engines are equipped with SGen5-2000H generators. EPC contractor is the in-country MAPNA Group, which was awarded a license by Siemens for manufacturing gas turbines in Iran. More than 20 gas turbine/generators are planned for the country over the next four to five years.

Argentina’s Albanesi SA orders seven SGT-800 gas turbines—two each for the Rio Cuarto and San Miguel de Tucuman powerplants and three for the city of Ezeiza. These units will be supplied from the company’s Finspong (Sweden) factory, bringing the total number of SGT-800s sold worldwide to 300 since the engine was introduced as the GTX100 in 1997. The largest model in the SGT-800 series is capable of producing 54 MW at a nominal efficiency of 39%. In related news, the international energy group SoEnergy orders two Trent 60 machines for service in Argentina. They will be made in the US and Canada.

Sudanese Thermal Power Generating Co purchases five SGT5-2000E gas turbines with a combined generating capacity of 850 MW for commercial service by the end of 2017. SGen5-100A generators will be coupled to the GTs. Three of the simple-cycle machines will be located at the Garri Power Station north of Khartoum, the other two on the Red Sea coast. Fuel flexibility was critical to the OEM’s success on this order: The units are designed to burn natural gas, heavy fuel oil, and light diesel.

GE update

GE inks Exelon to a five-year contract to use the OEM’s software to analyze and manage the utility’s 91 US powerplants, which produce nearly 33 GW and supply more than 10 million customers. This is GE’s largest such deployment in the power sector and one of the three largest sales of its Predix industrial operating system thus far. GE Power’s Steve Bolze, was quoted as saying the company’s technology has increased powerplant efficiency by 3% and reliability by 5%, while cutting O&M costs by 25%.

Southern California Edison announces it will install the world’s first battery storage and gas-turbine hybrid. The LM6000 Hybrid EGT, scheduled for installation at two SCE sites in the coming months, involves installation of a battery energy storage system from Current, powered by GE, and upgrades to an LM6000 gas turbine to integrate the two systems. The solution, developed in collaboration with Wellhead Power Solutions LLC, qualifies for the CAISO’s contingency-reserve tariff.

Vattenfall Europe Warme AG selects GE Power Services to overhaul and extend the operating life of two 130-MW steam turbines (COD 1963 and 1993) at the Wedel district-heating plant in Hamburg, Germany.


Sulzer expands its capabilities for the repair of steam turbines with the upgrade of facilities at the company’s Piedmont (SC) shop. It is now equipped to carry out complete refurbishments of steam-turbine packages up to 750 hp in addition to the services already delivered—including balancing and governor overhauls.

Emerson Electric Co has consolidated its five business segments (Emerson Process Management, Network Power, Industrial Automation, Climate Technologies, and Commercial and Residential Solutions) into just two: Emerson Automation Solutions and Commercial and Residential Solutions. Emerson Automation Solutions essentially is what was Emerson Process Management, the entity likely most familiar to owner/operators of generating equipment, plus a few other companies. Some businesses, such as Network Power, which makes power systems that work with telecommunications and data networks, were spun off.

The restructuring, announced in mid-2015, was finalized Oct 1, 2016 to build value for customers, employees, and shareholders. The realignment is said to create a highly focused portfolio organized around a solutions-centric business model to deliver on the company’s promise: “Consider it Solved.”

Clark-Reliance Corp introduces the Jerguson® LumaStar™ EPL-316 illuminator, which provides high-contrast, white LED light, to provide superior gage visibility day or night. LED lights essentially are maintenance-free and rated for approximately 100,000 hours of service.

MTU Maintenance extends its exclusive contract with Thailand’s Rojana Power for the power producer’s nine LM6000 engines. The 10-yr agreement covers both scheduled and unscheduled maintenance events as well as onsite services. Recall that MTU’s Berlin-Brandenburg facility is a GE-licensed Level IV depot with one of relatively few test cells worldwide equipped to handle LM2500 and LM6000 engines.

Alta Solutions Inc releases its AS-7000 machinery protection system, which merges an API 670 fifth-edition MPS with Alta’s real-time gapless data acquisition—thereby enabling the automatic capture of high-resolution machinery data for subsequent analysis.

U.S. Water’s PhosZero™ chemistry was among the 2016 finalists in the R&D 100 Awards Program. The technology provides both scale and corrosion protection with reduced aquatic toxicity. It is designed to provide users a phosphorus-free cooling-water treatment that both achieves desired performance results while meeting regulatory requirements.

In related news, the company acquires Water & Energy Systems Technology Inc (WEST) to service customers in the Southwest. The California company has nearly two decades of experience providing specialty chemicals and engineering services for water treatment.
