Combustion, Fuels & Emissions Track

Aero and Industrial Gas turbines with low specific fuel consumption and reduced CO2 emissions require high combustor outlet temperatures with a continued emphasis on reducing emissions, without sacrificing operability or durability. In addition, Combustion systems are increasingly expected to operate with synthetic gaseous fuels or alternative liquid fuels. The Combustion, Fuels & Emissions sessions will highlight new technology and design approaches, using both experimental and computational techniques, employed to achieve improved combustor performance including ultra-low pollutant emissions and enhanced operability such as turndown and transient response. Broad trends for the 2017 conference include a continued focus on combustion dynamics for lean-staged combustion systems, significant innovation in the development of combustion system such as Dry Low NOx or novel rotary detonation, maturation of large eddy simulation analyses, as well as continued research of fundamental and applied topics in automation, mixing, ignition, autoignition, blowout and chemical kinetics.

Cycle Innovations - Energy Storage Track

With continuing interest in clean energy and energy storage through the production and use of Hydrogen (H2), there is a growing need to fully understand the impact of H2 on existing infrastructure while also looking into the development of new technologies for future demand. This tutorial will take a detailed look into H2 applications and the challenges that it presents, whether it is the use of pure H2 or blending hydrogen with natural gas in existing pipeline infrastructure.  Various applications that will be looked at are Propulsion, Petrochemical, and Energy Storage. In addition, this tutorial go over methods of H2 production and H2 compression to look at how the H2 is created and how it is injected into pipelines, fuel cells, and other forms of storage. In terms of compression, H2 presents many challenges due to its low molecular weight and high head rise to pressure ratios. It is important to look into existing technologies that are used for current hydrogen production but also understand their limits and capabilities while also looking into novel designs as demand continues to increase. After compression, there is a need to look into various methods for storing hydrogen, whether it is through liquid which will require more cooling, high pressure gas, carriers, sorbents, and additional options. Another challenge with H2, is its effect on materials typically used in pipeline systems. Due to its molecular size, hydrogen embrittlement at higher pressures is a serious concern as it could potentially weaken high pressure storage vessels and pipelines and lead to premature failure. This leads to a need to understand what materials are most effective with high concentrations of H2 while also understanding the impact on existing materials. This leads to a detailed breakdown of the potential for hydrogen blending and what concentrations are acceptable without compromising existing infrastructure to reduce cost and lead time for injecting more H2 into the pipelines. Lastly, the tutorial will look at H2 impacts on combustion by diving into combustion fundamentals, capabilities with current technologies, and novel designs that can improve performance with H2.

Cycle Innovations - Energy Storage Track

Grid-scale energy storage is needed to enable deep penetration of renewable power generators like solar photovoltaic and wind farms into the energy mix. The minute-by-minute, hourly, and seasonal variability associated with these renewable resources is poorly matched with power usage. Conventional power generation from fossil fuels or nuclear sources is typically required in order to provide sufficient power quality and reliability, although this approach results in operational profiles that require significant ramp rates and turndown, reducing the efficiency and life of conventional plants. Grid-scale energy storage systems would absorb power from the grid during periods of excess renewable generation, and release the stored energy to generate power when renewable sources are unavailable. Lithium-ion or other battery chemistries are being introduced as a potential solution, but all existing technologies are currently cost-prohibitive at the many Megawatt- or Gigawatt-scales for more than about 2-4 hours.

There are many existing or developing machinery-based energy storage systems to fulfill this need, including pumped hydro, flywheels, compressed air, gravitational, liquid air, pumped thermal (example images below), and various thermochemical technologies such as hydrogen, ammonia, synthetic natural gas, sulfur, and other "Power-to-X" technologies.

This tutorial reviews all of these technologies including basic working principles, role of turbomachinery, hybridization with existing power generators, state of development, advantages and disadvantages relative to other technologies, and research & development needs for system improvements and commercialization.

Gas turbines (GT) could be ready for wide-scale commercial operation with low-carbon fuels within the next 10 years, but broad deployment will likely depend on successful, near-term field demonstrations.

The degree to which the existing GT power generation fleet ultimately transitions to blended fuels will depend upon equipment/hardware capability, policy changes, financial incentives, and the availability of sufficient quantities of these alternative fuels at an acceptable price.

Technical hurdles must be addressed to allow for safe and reliable operation of combustion assets with blended fuels. Many lab- and pilot-scale studies have previously focused on combustion characteristics and results suggest fuel blending could be accomplished with modifications to existing equipment. However, full-scale testing is needed to ensure that operation behavior is understood over the range of conditions that these machines, especially F-class and above GTs, are expected to operate.

The GT owners and operators are faced with many challenging tactical and strategic decisions with their existing GT fleet as well as needs and requirements in the long-term perspective for the next generation fleet. The objective of this session is to highlight operational and research needs both in the short-term and long-term as guidance for the equipment suppliers and the research community.

The Panel Members will address these issues over two time periods:
1. The GT user communities needs in the next 10 years: Gas turbines development and retrofit needs in the energy transition (up to approx. 2030)
• Introduction by Rob Steele, EPRI
• Tomas Alvarez Tejedor, ENEL
• Aaron Guthrey, LADWP
• Jay Lim, LADWP
• Lawrence Sparks, TVA

2. The GT user communities needs for a continued transition to low carbon/carbon-neutral society: Most promising R&D opportunities and key research fields (approx. 2030-2050)
• Introduction by Christer Björkqvist, ETN Global
• Olaf Brekke, Equinor
• Sigrid Gijbels, Engie

Improvements in fans and blowers are means to address the global energy challenge, with manufacturers increasingly focusing on improvement in fan efficiency under legislative pressure and as a part of their response to global climate change.

The academia-industry collaboration and the up-front use of Computational Fluid Dynamics (CFD) and Experimental Fluid Dynamics (EFD) are the key ingredients to facilitate the advancement from traditional empirical design methodologies. In response to these challenges, the ASME-IGTI Fans and Blowers Technical Committee consider all technical aspects associated with fans and blowers, with a special emphasis on:

• Design and optimization
• CFD methods for unsteady aerodynamics
• Noise generation, prediction, innovative noise reduction design
• Psycho-acoustic and noise perception in installations
• Structural mechanical aspects (vibration, fatigue and flutter)
• Emerging technologies in flow and noise control
• Operations and system effects and interactions
• Maintenance, repair & life time management
• Standards, compliance with legislation & regulations
• Evaluation of education curricula for fan technology and systems
