  • Physics-based data analysis for wind turbine condition monitoring

    • Authors: Luo H.
      Pages: 4 - 22
      Abstract: This article presents methodologies for improving wind turbine condition monitoring using physics-based data analysis techniques. The unique operating conditions of the wind turbine drivetrain are described, and the complex kinematics of the gearbox is analyzed in detail. The pros and cons of the current wind turbine condition monitoring system (CMS) are evaluated. To improve the wind turbine CMS capability, it is suggested to use linear models with unsteady excitations, instead of using nonlinear and nonstationary process models, when dealing the wind turbine dynamics response model. An analysis is undertaken of the damage excitation mechanisms cause for various components in a gearbox, especially for those associated with lower-speed shafts. Physics (mechanics)-based data analysis methods are presented for different component damage excitation mechanisms. Validation results, using the wind farm and manufacturing floor data, are reported.

  • A review of Danish integrated multi-energy system flexibility options for
           high wind power penetration

    • Authors: Wang J; Zong Y, You S, et al.
      Pages: 23 - 35
      Abstract: The current status of wind power and the energy infrastructure in Denmark is reviewed in this paper. The reasons for why Denmark is a world leader in wind power are outlined. The Danish government is aiming to achieve 100% renewable energy generation by 2050. A major challenge is balancing load and generation. In addition, the current and future solutions of enhancing wind power penetration through optimal use of cross-energy sector flexibility, so-called indirect electric energy storage options, are investigated. A conclusion is drawn with a summary of experiences and lessons learned in Denmark related to wind power development.

  • Progress of circulating fluidized bed combustion technology in China: a
           review

    • Authors: Cai R; Ke X, Lyu J, et al.
      Pages: 36 - 49
      Abstract: Circulating fluidized bed (CFB) technology plays an important role in the utilization of low-grade coal in China. This article reviews CFB combustion technology development in China and summarizes recent achievements. Since 1990 Chinese engineers and researchers have been undertaking work to improve CFB boiler technology. A completely novel CFB boiler design theory was developed and used in the domestic manufacturing of CFB boilers with various capacities. China is the largest supplier and customer of CFB boilers in the world due to the widespread use of CFB boilers. In 2007, the lower energy consumption CFB technology was successfully developed by re-specifying the fluidization state, which reduced the power consumption of forced fans and solved the potential erosion problems on the water wall. Afterwards, in order to increase the electric power generation efficiency, the supercritical CFB (SCCFB) boiler was developed and the first 600 MW SCCFB boiler was demonstrated and put into commercial operation in 2013. The success of the technology is evident with over 80 SCCFB boilers on order with capacities of 350 MW to 660 MW. Chinese scientists and engineers are also developing technology to lower the emissions of CFB combustion to meet the requirements of China’s strict emission regulations. This emission reduction is through high-efficiency desulfurization by limestone injection into the furnace and low NOx combustion, ultra-low emission of SO2 and NOx in the furnace can be realized by improving the bed quality and increasing the solid circulation rate. There is currently further research and design development being undertaken to develop a 660 MW ultra-supercritical CFB (USCCFB) boiler. The new boiler is expected to be operational before 2020 resulting in higher efficiency and lower energy consumption and emissions.

  • Experimental study on dense-phase pneumatic conveying of coal powder at
           high pressures

    • Authors: Guan Q; Liu Z, Fang X, et al.
      Pages: 50 - 67
      Abstract: Clean utilization and conversion of coal resources is significant to China’s energy sustainable development. Entrained-flow coal gasification technology is an important method used for clean and efficient conversion of coal. The characteristics and stability of high-pressure dense-phase pneumatic conveying of pulverized coal is crucial to the safe and stable operation of dry-feed entrained-flow coal gasifiers. Dense-phase pneumatic conveying experiments were carried out using a high-volatile bituminous coal in pipes with diameters of 25, 15 and 10 mm, respectively, and at back pressures of 1.0–4.0 MPag. The conveying characteristics and effects of operating and structure parameters were studied. Pressure drop models were established for horizontal and vertical upward conveying. The prediction uncertainty was within ±30% for the horizontal conveying and ±20% for the vertical upward conveying. The relative standard deviation of solid flow rate was proposed to explain conveying stability. The effect of operating parameters on conveying stability was systematically analyzed. The gas velocity-related criterion was proposed for stable conveying.

  • Innovative power generation systems using supercritical CO2 cycles

    • Authors: Zhu Q.
      Pages: 68 - 79
      Abstract: Supercritical carbon dioxide (sCO2) power cycle is an innovative concept for converting thermal energy to electrical energy. It uses sCO2 as the working fluid medium in a closed or semi-closed Brayton thermodynamic cycle. The sCO2 power cycles have several benefits such as high cycle efficiency, small equipment size and plant footprint (and therefore lower capital cost) and the potential for full carbon capture. Achieving the full benefits of the sCO2 cycle depends on overcoming a number of engineering and materials science challenges that impact both the technical feasibility of the cycle and its economic viability. For example, the design and construction methods of turbomachinery, recuperator and high-pressure oxy-combustor pose significant technical challenges. Other R&D needs include material selection and testing, and optimized power cycle configuration. Over the years, particularly in the last decade, R&D efforts have been growing worldwide to develop sCO2 cycle technologies for power generation. Significant progress has been made in developing sCO2 cycle power systems. Some small, low-temperature sCO2 Brayton cycle power systems are starting to emerge in the commercial market, and a natural gas-fired demonstration power plant using a sCO2 cycle called the Allam Cycle is under construction. This article describes the sCO2 cycles for applications in power generation from fossil fuels and reviews the recent developments in sCO2 power cycle technologies.

  • Preparation of large, ultra-flexible and free-standing nanomembranes of
           metal oxide–polymer composite and their gas permeation properties

    • Authors: Mersha A; Selyanchyn R, Fujikawa S.
      Pages: 80 - 89
      Abstract: In this work, fabrication of free-standing nanomembranes of metal oxide (MOx) and polymers by simple spin-coating method is discussed. First, double-layer nanomembranes containing MOx and epoxy resin of polyethyleneimine and poly[(o-cresyl glycidyl ether)-co-formaldehyde] were prepared. Free-standing nanomembranes were successfully prepared, but defects formed in the metal oxide nanolayer during sharp bending of the nanomembrane. To overcome fragility of MOx nanolayer, poly(vinyl alcohol) nanolayers were introduced between MOx nanolayers by layer-by-layer (LbL) assembly process. The LbL nanomembrane was also free-standing and was highly flexible during macroscopic membrane manipulations. Even after transfer of the LbL nanomembrane onto a porous support, it did not have apparent cracks, confirmed by scanning electron microscopy (SEM). The LbL nanomembrane sustained low gas permeance, confirming the absence of significant defects, although it shows excellent flexibility. We believe that the presented LbL nanomembrane could be a platform useful for the design of molecular nanochannels, which is the next challenge for efficient gas separation.

  • Renewable hydrogen production from butanol: a review

    • Authors: Patel R; Patel S.
      Pages: 90 - 101
      Abstract: Hydrogen production from butanol is a promising alternative when it is obtained from bio-butanol or bio-oil due to the higher hydrogen content compared to other oxygenates such as methanol, ethanol or propanol. Catalysts and operating conditions play a crucial role in hydrogen production. Ni and Rh are metals mainly used for butanol steam reforming, oxidative steam reforming and partial oxidation. Additives such as Cu can improve catalytic activity in many folds. Moreover, support–metal interaction and catalyst preparation technique also play a decisive role in the stability and hydrogen production capacity of catalyst. Steam reforming technique as an option is more frequently researched due to higher hydrogen production capability in comparison to other thermochemical techniques despite its endothermic nature. The use of the oxidative steam reforming and partial oxidation has the advantages of requiring less energy and longer stability of catalysts. However, the hydrogen yield is less. This article brings together and examines the latest research on hydrogen production from butanol via steam reforming, oxidative steam reforming and partial oxidation reactions. In addition, the review examines a few thermodynamic studies based on sorption-enhanced steam reforming and dry reforming where there is potential for hydrogen extraction.

  • A concept to support the transformation from a linear to circular carbon
           economy: net zero emissions, resource efficiency and conservation through
           a coupling of the energy, chemical and waste management sectors

    • Authors: Lee R; Keller F, Meyer B.
      Pages: 102 - 113
      Abstract: Coal and carbon-containing waste are valuable primary and secondary carbon carriers. In the current dominant linear economy, such carbon resources are generally combusted to produce electricity and heat and as a way to resolve a nation’s waste issue. Not only is this a wastage of precious carbon resources, which can be chemically utilized as raw materials for production of other value-added goods, it is also contrary to international efforts to reduce carbon emissions and increase resource efficiency and conservation. This article presents a concept to support the transformation from a linear ‘one-way cradle to grave manufacturing model’ toward a circular carbon economy. The development of new and sustainable value chains through the utilization of coal and waste as alternative raw materials for the chemical industry via a coupling of the energy, chemical and waste management sectors offers a viable and future-oriented perspective for closing the carbon cycle. Further benefits also include a lowering of the carbon footprint and increasing resource efficiency and conservation of primary carbon resources. In addition, technological innovations and developments that are necessary to support a successful sector coupling will be identified. To illustrate our concept, a case analysis of domestic coal and waste as alternative feedstock to imported crude oil for chemical production in Germany will be presented. Last but not least, challenges posed by path dependency along technological, institutional and human dimensions in the sociotechnical system for a successful transition toward a circular carbon economy will be discussed.
