Turbochargers, nowadays, are becoming increasingly common in the internal combustion engines of automobiles in order to improve fuel economy and meet government emission regulations. A turbocharger must provide a designed increase in pressure under load condition (design point) while generating enough power at the low end (loss mass flow region). Internal combustion engine working characteristics, however, prevent a centrifugal compressor from generating enough boost at the low end when radial turbine rotational speed is low. (more…)
It was announced this week that Siemens, a German electronics and engineering company, has made a deal to purchase Dresser-Rand, a US-based oilfield equipment manufacturer. This agreement concludes a bidding war between Siemens and Sulzer, a Swiss pump manufacturer.
The deal, worth $7.6 billion, will give Siemens direct access to US domestic oil production, a sector currently booming from new extraction techniques like hydraulic fracturing. Houston, Texas is a primary hub for the oil industry and this location is an ideal place for Siemens to enter the growing US market. Siemens has already played a role in the US power industry, mainly with its production of gas turbines. The company is also purchasing Rolls-Royce Holdings PLC’s energy gas turbine and compressor business, including its Houston operations. (more…)
Mini and Micro gas turbines are becoming increasingly relevant among today’s research of power production technologies. These turbines are smaller, lighter, less-polluting, and less expensive than traditional power generation units. Gas turbines have high-grade waste heat, low maintenance costs, and low vibration levels. The micro versions of these turbines play a key role in micro combined heat and power (CHP) and micro power generation. (more…)
On September 15th, 2014 SoftInWay will be launching a beta release of its new Learning Center. The center will provide users with the knowledge necessary to design, analyze, and optimize efficient turbomachinery. The center will act as an alternative education option to SoftInWay’s full classroom training courses. Those with time, travel, or budget limitations can use the center to acquire engineering knowledge in the fundamentals and hands-on applications of turbomachinery. (more…)
The 43rd Turbomachinery and 30th Pump Symposia are quickly approaching. The 3-day event will begin on September 22nd in Houston, Texas at the George R. Brown Convention Center. The Symposia are organized in order to promote professional development, technology transfer, peer networking and information exchange among industry professionals. The event serves as a premier training and networking opportunity for professionals in both the turbomachinery and pump industries.
In ancient Greece, a symposium was a drinking party. Hosted by Socrates and philosophers alike, they were used to celebrate and discuss matters most vital to the universe. The “symposium” was a source of pride for the ancient aristocrats. (more…)
GE considers buying Alstom but so is Siemens. What’s going to happen to the service market?
Currently Alstom covers 25% of the world’s service market and is the world’s third largest provider of equipment and services for power generation. (Source: Alstom)
Power plants are aging as we speak, so the service market is attracting the attention from different service providers.
This past Tuesday was the 44th celebrated Earth Day. On Earth Day, more than 100 countries join together to literally stop and smell the roses, appreciate the splendor and beauty of Mother Nature and take extra efforts to be more conscientious for our shared home.
Turbomachinery, though not always the first thing that comes to mind when speaking on the subject of green technology, plays an important role toward our efforts for a more sustainable environment.
Yes, the Formula 1 races have begun. The world is three races in with the fourth Grand Prix scheduled for April 20 in China. As the world watches in awe at the versatility and speed (let’s face it, the races are all about the cars, right?), engineers marvel at the aerodynamics, energy recovery systems, turbochargers and internal combustion engines (because we love engineering).
The supercritical CO2 power cycle is one of the most promising power technologies. It is not by chance though, because carbon dioxide (CO2) has a unique combination of attributes, such as a low critical temperature, an environmentally natural origin, a high standard of safety and a low cost. Carbon dioxide is also thoroughly studied, therefore there is sufficient information surrounding it. But on the other hand, the supercritical CO2 cycle has a high energy conversion factor, such as high thermal efficiency.
The goal of this test case is to find the gas turbine necessary to produce 58 MW of total net power for the conversion of a steam turbine to a combined gas-steam cycle while providing the highest level of cycle thermal efficiency.
The exhaust gases from the gas turbine are used to heat up steam through three HRSGs (Heat Recovery Steam Generators) in series. The steam is then used in the studied steam turbine which is comprised of two “cylinders” in series.
