Mastering Steam Turbine Operations in the Modern Energy Landscape

Mastering Steam Turbine Operations in the Modern Energy Landscape

Despite the growing focus on renewables and decarbonisation, steam turbines are indispensable in power plants—still delivering optimal performance and enhanced plant efficiency, reliability and safety measures.

The ongoing sustainable energy transition and geopolitical events, such as the Russian-Ukraine war, have intensified the reliance on thermal power plants. Renewable fuel sources are on the surge. Coal-fired power plants have dynamically changed power outputs.

Steam turbines, as the core of the power generation energy sector, are under pressure to ensure higher plant availability to accommodate dynamic operational requirements—cycling more frequently to balance loads, optimising fuel costs and integrating renewables into their grid.

Ensuring plant efficiency and reliability

Achieving plant efficiency and reliability in the ever-evolving landscape of power generation requires a strategic approach, and the effective operation of steam turbines plays a critical role in this pursuit.

“With the adoption of renewables, power plants are now, more than in the past, required to adjust their output and balance the supply and demand to compensate for the variable electricity supply from renewable sources,” QianXi Koh, Asia Pacific Power Industry Manager for Control Valves and Instruments at Emerson stated, stressing that this is likewise the case for many coal-fired power plants, with operations shifting gears from base-load to peaking-load amidst the waves of renewables.

The main challenge with cycling loads, however, is thermal stress. Operating conditions pose increased thermal and mechanical stresses on major equipment and components, resulting in fatigue and failure. This leads to frequent outages and maintenance, reduced plant availability, and higher costs of repair and manpower.

Yielding operational excellence through advanced control technology for steam turbines

Advanced control technology emerges as a crucial factor in the quest for operational excellence. Steam turbines, being substantial investments for power plants, demand precise and advanced control technology to maintain performance and protect this critical asset.

These require not only peak performance but also robust protection against operational challenges. To address these demands head-on and tackle the challenges posed by varying loads, Emerson's portfolio utilises reliable steam conditioning, turbine bypass, and effective isolation of the steam turbine during different operational phases.

The Fisher™ ATST Steam-Atomized Desuperheater and the Sempell™ Bled Steam CheckValve, for instance, showcase the transformative impact of technology on steam turbine efficiency and reliability. The ATST desuperheater's additive manufacturing-enabled steam-atomized water injection forms extremely fine water droplets into a fog-like mist over a wide operating range, ensuring optimal temperature control and reducing piping wear. Meanwhile, the Sempell check valve prevents steam backflow from the pre-heaters to the steam turbine, safeguarding the turbine from potential damage during emergency stops.

Improving safety measures and leveraging data analytics

Maintaining the reliability of steam turbine operations comes with ensuring their safety, and the features of non-return turbine protection check valves play a crucial role in this regard. Such features include:

Complete disc closure at no-flow conditions
Anti-rotational devices to avoid damage from induced flow instability
Free-swinging disc operation
A vertical seat design
And rapid closure during fast air exhaust, amongst others

These elements collectively contribute to reduced internal turbulence and pressure loss, ensuring the longevity of the turbine.

In the era of Industry 4.0, power plant operators can also leverage data analytics and digital solutions to fine-tune operations with real-time insights into the performance of steam turbines. Predictive maintenance based on data-driven assessments allows for identifying potential issues before they escalate.

For example, valves, critical components in the turbine operation, can be monitored using Emerson's Valve Condition Monitoring service. This real-time, non-intrusive health monitoring by Emerson valve experts allows operators to identify poorly performing valves through diagnostics, enabling a proactive approach to shutdowns and turnarounds, addressing issues before they impact plant operations.

Getting to Know the Indramayu PLTU, a Power Plant on the East Side of West Java

Indramayu, January 19, 2020 – The Indramayu PLTU is a steam-powered power plant located in Sumuradem Village, Sukra District, Indramayu Regency, West Java. The power plant managed by a subsidiary of PLN, PT Pembangkitan Jawa Bali (PJB) has a total energy capacity of 3×330 megawatts (MW).

The energy produced by this power plant is capable of supplying electricity in the Java and Bali regions. Since 10 years ago, the Indramayu PLTU has been known as a national vital object, which supplies electricity to Java and Bali, especially the West Java and DKI Jakarta areas.

The northern side of the Indramayu power plant is directly adjacent to the north coast of Java Island. On the other side, this power plant is surrounded by green rice fields.

In 2019, PLTU Indramayu successfully received the Green Proper award. Proper is a program to assess the performance rating of companies in environmental management developed by the Ministry of Environment (KLH) since 1995. This program is carried out to encourage companies to improve their environmental management.

Green Proper is given to companies that have carried out environmental management beyond that required by KLH.

PLTU Indramayu utilizes the remaining coal combustion results in the form of fly ash and bottom ash to be processed into paving blocks.

"The production is not too big yet, we can produce 500 paving blocks every day. The results of the paving blocks are used for corporate social responsibility activities for residents around the power plant," said General Manager of UBJOM Indramayu, Ubaedi Susanto.

As one of the largest rice producing areas in West Java, PT PJB also continues to support agriculture around PLTU Indramayu by encouraging the community to use organic fertilizers through various training and coaching.

"Previously, people were worried that using organic fertilizer would reduce the results, but it turned out to be the same as using synthetic fertilizer, even though the operational costs of using organic fertilizer are cheaper. Now many people are interested," said Ubaedi.

TRIAL OF USING WOODEN PALLETS AS A MIXTURE OF COAL FUEL

The Indramayu PLTU is also currently conducting a trial of using wooden pallets as a mixture of coal to generate electricity.

Ubaedi explained that every day the Indramayu PLTU requires an average of 4,000 tons of coal per unit, so that the total requirement if 3 units are operating reaches 12,000 tons. By utilizing pallets, it is hoped that coal usage can be reduced.

"Currently it is still in the trial stage. Yesterday we tried mixing 5% of pallets and the results were quite satisfactory," said Ubaedi.

The target of this innovation in using pallets is not only to save the basic cost of provision, but also to become an alternative energy to replace fossil fuels. This innovation can also reduce waste and emissions which are currently still a problem in several areas.

In addition to the Indramayu PLTU, there are 16 PLN power plants that received the Green Proper, namely the Priok PLTGU, Suralaya 1-7 PLTU, Pelabuhan Ratu PLTU, Gunung Salak PLTP, Suralaya 8 PLTU, Paiton 9 PLTU, Tambak Lorok PLTGU, Muara Tawar PLTGU, Rembang PLTU, Gilimanuk PLTG, Perak Grati PLTGU, Pemaron PLTG, Lontar PLTU, Keramasan PLTGU and Labuan PLTU.

Even five PLN power plants managed to get the gold Proper, namely the Tanjung Jati B Steam Power Plant (PLTU), Jepara which is managed directly by PLN, Paiton Unit 1-2 PLTU, Probolinggo and Gresik Gas Steam Power Plant (PLTGU) managed by PJB, as well as Pesanggaran Diesel Gas Power Plant (PLTDG), Denpasar and Kamojang Darajat Geothermal Power Plant (PLTP), Bandung Regency which are managed by IP.

The Gold Proper is the highest award given to companies that have carried out environmental management beyond the requirements and have made efforts to develop the community sustainably.
