A new process for cleaning the fin tubes in HRSGs in combined-cycle power plants can remove rust and other deposits on components using a gas actuated pressure wave. "The Bang&Clean process uses high pressure to vibrate the fin tubes slightly to remove rust and other deposits in a process that takes far less time than traditional methods and at a much lower cost," Robin Buller, UK Director at KRR ProStream told Gas to Power Journal.
New research at the Berlin Institute of Technology promises to improve matching processes for gas turbines and turbocharger units. "The implementation of the concept of measurement uncertainty can be carried out directly on the test bench and should hopefully lead to significant cost savings in the near term," Holger Mai, lead researcher on the project said, speaking to Gas to Power Journal.
The use of single-shaft power trains, in multi-unit power plants, enables the units to be used independently and react swiftly to changing demand patterns. "In a single-shaft power train, the gas turbine and steam turbine share one generator, which eliminates the need for an additional generator and downstream electrical equipment. This not only reduces costs but also renders a more compact design, Siemens Energy Solutions Director of Marketing Rick Loose told Gas to Power Journal.
A consortium of turbine manufacturers, power plant producers and shipbuilders have signed a Memorandum of Understanding to design and build a 880MW mobile power plant ship. The project will be developed jointly at a cost of $940 million by Siemens Energy Solutions, Hyundai Heavy Industries, Polaris Shipping and Korea Midland Power and a prototype is expected to be operational by December 2017.
US-based PowerPHASE has developed TurboPHASE, a compressed-air system for boosting gas turbines that can deliver peak power output within a minute or so after pressing the 'start' button. An 80MW TurboPHASE on an 800MW 2x1 power plant can be installed system ready in three working days on a space of around 630 square metres.
An announcement on whether the UK government will co-fund research for the world's first Carbon Capture and Sequestration (CCS) project for gas-fired power is expected 'early in the new year,'sources have told Gas to Power Journal.
Initial funding of at least £20 million would provide for Front End Engineering Design (FEED) studies at Shell's Peterhead site in the North of Scotland to analyse and de-risk the costs of commercialising CCS technology.
American multinational, General Motors (GM), has announced plans to invest $24 million in two power plants fuelled by landfill gas. The plants will be based at the company's Fort Wayne, Ind., and Orion, Mich., assembly plants and will increase total onsite gas power generation to 40% and 54% ot total consumption respectively.
With gas turbines increasingly used from the smallest to the largest scales of power generation systems, the technical scope of machinery has grown dramatically in recent years. Modern Gas Turbine Systems, published by Woodhead Publishing, gives a comprehensive introduction and overview to the subject, outlining the mechanical principles and underlying physics of gas power generation, and describing a range of operational concerns relevant to plant operators and engineers.
Rare but catastrophic failures in gas turbines may soon be preventable thanks to research conducted at the Chinese Academy of Science. "Our research aims to widen the operating range of for gas turbine engines, preventing lean blow-out and reducing the pollution emission by optimization of fuel atomization," Liu Cunxi, researcher at the Academy's laboratory of light duty gas turbines told Gas to Power Journal.
