Many of the component failures occurring in service can be delayed by better incorporation of tribological principles into engineering design and maintenance. However, the concept of tribology has not yet penetrated successfully into the industry in general and there is an urgent need for the practical tribology design criteria and transference of tribological knowledge to the engineering ...

During one of the routine inspections in a nuclear power plant, it was found that a tenon of one of the third-stage blades of the Low-Pressure (LP) turbine had been worn/broken off the turbine blade, leaving only the remaining tenon riveted to the shroud piece. With only one of the two tenons remaining, the blade was at risk of getting freed from the shroud piece. Hence, it was necessary to ...

The purpose of this paper is to propose a new behavioural evaluation of a large steam turbine during the run-up period based on a numerical simulation of the transient fluid dynamic processes that occur in the turbine during start-up. The transient process begins when the run-up valve starts its opening trip and ends when the rotor speed achieves the required value. This original approach is a ...

Located on the north west of Africa, just across from the narrow Strait of Gibraltar, Morocco’s dry and sandy terrain has made it a leader in solar energy production. As a relatively developed country in its own right, Morocco is electrified and at the start of the 21st century, more than 50% of all electricity was produced by burning fossil fuels. However, the authorities in Morocco ...

Today, combined cycle gas turbine (CCGT) plants play a critical role in providing power grids with additional electricity during peak periods of high demand. By harnessing the energy from both combustion and steam turbines. CCGT plants use less fuel overall and can run longer than traditional "peaker' plants to produce cheaper electricity on demand. Depending on the condition of the region's ...

Water and power are intimately connected in the U.S. and around the world. In 2015, electric power generation was responsible for 41% of total water withdrawals in the United States, according to the U.S. Geological Survey. Where does all that water go and what role does it play in power generation? HOW POTABLE WATER IS USED IN POWER GENERATIONELECTRICITY GENERATION Approximately 90% of ...

Sulzer completed an overhaul of three General Electric steam turbines and five Clark compressors for a large ethylene plant in Colombia. Sulzer’s service centers in Texas and Bogotá worked together to inspect and repair the three turbines. Sulzer staff helped the customer with project planning, full commissioning, and testing within a very tight timeframe. The city of ...

January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of catastrophic ...

This paper presents the reasons and merits of using cogeneration generation power desalting plants (CPDP), the different methods used to rate their performance, and their drawbacks. The ratings of the CPDP are crucial, because the fuel cost allocation between the water and power depends on the rating method used. The ratings are usually based on the first and the second laws of thermodynamics. A ...

THE BENEFITS OF SOLAR THERMAL POWER PLANTS Solar thermal energy production requires two main things: sunlight and equipment to capture, store and disperse the energy. Only two types of solar thermal systems exist. They are the passive systems, which do not require equipment (such as the heat build-up in your car whenever you park it in the sun), and active systems which require a method to ...
