cigs-solar-pv-cell-bg.jpgDow Building Solutions has commissioned the help of Global Solar Energy in its effort to manufacture solar roof shingles. These shingles are an effort to create an innovative BIPV or building-integrated photovoltaic technology for Dow’s participation in the U.S. Department of Energy SAI (Solar America Initiative). According to Dow, it has chosen Global Solar as a partner because the latter is the sole company able to provide flexible Copper Indium Gallium diSelenide (CIGS) material used for the PVs, which actually meets SAI’s requirement of having 10 percent efficiency, as well as fits Dow’s needs to a T. CIGS is perfect for the type of BIPV technology Dow is creating because of its low cost and high efficiency. Dow’s aim is to lower the cost of solar panels, specifically BIPVs, making solar energy a competitive source of energy, as builders and architects are given free reign on how they want to position the BIPVs due to their inherent flexibility.

Beyond the scientific computing and computational science research embedded in the Office of Science (SC) Core Programs, SC invests in a portfolio of coordinated research efforts directed at exploiting the emerging capabilities of terascale and petascale computing (http://www.osti.gov/scidac/). The research projects in this portfolio respond to the extraordinary difficulties of realizing sustained peak performance for those scientific applications that require terascale and petascale capabilities to accomplish their research goals. They respond also to the need for developing collaborative software environments where distributed resources and expertise are combined to address complex questions that no single institution can manage alone. In recognition of these difficulties, the SciDAC research projects are collaborative efforts involving teams of physical scientists, mathematicians, computer scientists, and computational scientists working on major software and algorithm development for and application to problems in the SC core programs, namely, Basic Energy Sciences, High Energy Physics, Nuclear Physics, Advanced Scientific Computing Research, Fusion Energy Sciences, and Biological and Environmental Research. Research funded under the SciDAC program must address the interdisciplinary problems inherent in ultrascale computing, problems that cannot be addressed by a single investigator or small group of investigators. The latter are typically funded by the core research programs. SciDAC Contact: (301) 903-3691.

Inverse combined steam-gas turbine cycle for the reduction of emissions of nitrogen oxides from combustion processes using fuels having a high nitrogen content

Document Type and Number:
United States Patent 5617715

An inverse combined steam-gas turbine cycle is disclosed. In the steam cycle, a fuel having a high nitrogen content such as coal or heavy fuel oil is burned in a boiler to raise steam to power a steam turbine. In the gas turbine cycle, a hydrocarbon fuel such as natural gas is burned in a gas combustor to power a gas turbine. The compressed exhaust gas (40. 42) from the steam cycle combustion is introduced into the gas combustor, where nitrogen oxides (NOx) in the exhaust gas may be reduced through reactions with the hydrocarbon fuel.

We claim:

1. A process for removing NOx emissions from a boiler fired by a high nitrogen content fuel, comprising:burning a high nitrogen content fuel in a boiler at atmospheric pressure to generate steam for a steam-turbine cycle and a waste gas including oxides of nitrogen;

burning a hydrocarbon fuel in a gas turbine combustor for a gas-turbine cycle to clean said waste gas of the oxides of nitrogen and to generate power;

compressing said waste gas from said boiler to a predetermined entering pressure of said gas turbine combustor;

introducing said compressed waste gas from said boiler into a fuel rich zone of said gas-turbine combustor to react with pyrolyzed fragments of said hydrocarbon fuel to convert NOx in said waste gas to N2 ;

adding an oxidant to said gas turbine combustor to complete combustion; and

directing exhaust gas from said combustor to a gas turbine.

2. The process of claim 1, further comprising removing sulfur compounds from said waste gas prior to entering said compressor to minimize damage to said gas turbine.

3. The process of claim 2, further comprising removing particulates from said waste gas prior to entering said compressor to minimize damage to said gas turbine.

4. The process of claim 3, wherein said particulates are removed at below 4 ppm.

5. The process of claim 1, wherein said hydrocarbon fuel comprises natural gas.

6. The process of claim 1, wherein substantially all of said waste gas is compressed and introduced into said gas combustor.

7. The process of claim 1, wherein said gas turbine combustor comprises a first fuel-rich combustion zone and a second fuel-lean combustion zone, and said compressed coal waste gas is introduced into said first fuel-rich zone at a downstream location, whereby said waste gas mixes with pyrolyzed hydrocarbon fragments of said fuel.



This invention relates to pollution control, and more particularly to pollution control for coal-fired combustion processes.

“The present invention provides a system for NO x emission reduction from boilers which burn fuels having a high nitrogen content, such as coal or a heavy fuel oil. An inverse combined steam-gas turbine cycle is provided. In the steam cycle, the fuel is burned in a boiler to raise steam to power a steam turbine. In the gas turbine cycle, a hydrocarbon fuel such as natural gas is burned in a gas combustor to power a gas turbine. The exhaust gas from the steam cycle combustion is introduced through a compressor into the gas combustor, where nitrogen oxides (NO x ) in the exhaust gas may be reduced through reactions with the hydrocarbon fuel. Thus, the combined cycle is the inverse of combined steam-gas turbine cycles known in the prior art, in which exhaust from the gas turbine cycle is introduced into the steam turbine cycle.”

“In the present invention, substantially all of the steam cycle flue gas may be introduced into the gas-turbine cycle. A compressor for the flue gas is provided to compress the flue gas to the predetermined input pressure for the gas combustor. The size of the compressor and gas combustor are determined by the amount of flue gas generated. Prior to entry into the compressor, the flue gas is preferably cooled to maximize its density, thereby minimizing the work input to the compressor, and any liquid droplets are removed. A scrubber to remove sulfur compounds and an electrostatic precipitator to remove particulates are also provided in the flue gas exhaust line upstream of the compressor. In this manner, the present invention effectively reduces the NO x emissions from a fossil fuel exhaust gas. If desired, the exhaust gas from the gas turbine may be utilized in the steam-turbine cycle.”

Résumé / Abstract

With the aim of constructing a comprehensive design optimization procedure of axial flow hydraulic turbine, an improved quasi-three-dimensional inverse method has been proposed from the viewpoint of system and a set of rotational flow governing equations as well as a blade geometry design equation has been derived. The computation domain is firstly taken from the inlet of guide vane to the far outlet of runner blade in the inverse method and flows in different regions are solved simultaneously. So the influence of wicket gate parameters on the runner blade design can be considered and the difficulty to define the flow condition at the runner blade inlet is surmounted. As a pre-computation of initial blade design on S2m surface is newly adopted, the iteration of S1 and S2m surfaces has been reduced greatly and the convergence of inverse computation has been improved. The present model has been applied to the inverse computation of a Kaplan turbine runner. Experimental results and the direct flow analysis have proved the validation of inverse computation

The Kaplan turbine was developed by Austrian engineer Viktor Kaplan around 1915. Kaplans are generally considered for low head high flow applications.

The Kaplan is an inward radial flow type reaction turbine similar to a Francis turbine. The turbine is usually placed in a spiral volute. Like a Francis turbine the Kaplan has a series of adjustable wicket gates. However the turbine runner (looking somewhat like a ship’s propeller) has adjustable blades. By changing the angle of the blades in tandem with the angle of the turbines the Kaplan can maintain a high efficiency even at very low flows.

Reaction Turbines like the Kaplan have a change in water pressure as the water passes through the turbine. There is pressure on the upstream side of the turbine runner and suction on the downstream side. On the downstream or outlet side of the turbine is the drafttube which slows the water as it exits the turbine. The draftube has a unique curved horn like shape.

Because Kaplans have a very flat flow to efficiency curve they are particularly suited to sites on rivers where the amount of available water varies greatly.

Radical polymers are aliphatic or nonconjugated polymers bearing organic robust radicals as pendant groups per repeating unit. A large population of the radical redox sites allows efficient redox gradient-driven and/or electric-field-driven electron transport through the polymer layer. Radical polymers are emerging as a new class of materials useful for energy storage, transport, and conversion devices.

Carbon-nanotube-titania composites exhibit enhanced photocatalytic properties over titania. The proposed mechanisms of catalytic enhancement resulting from the pairing of the titania semiconductor with either metallic, semiconducting, or defect-rich carbon nanotubes is discussed. The recent advances in the synthesis techniques for these composites and their photocatalytic reactions with organic, inorganic, and biological agents are also highlighted.

Few engineering materials are limited by their strength; rather they are limited by their fracture toughness. The resistance to fracture of a given material is intimately related to its microstructure. Perfect examples of this are biological materials that offer design strategies for the development of new composites that will open new possibilities in many structural applications demanding combinations of both strength and toughness.

Applying an electrical field to a dielectric may induce a large entropy and temperature change which is attractive for solid-state cooling. We present the general considerations and review the experimental efforts to achieve large electrocaloric effect (ECE) in dielectrics. We show that by operating above the order-disorder transitions, a large ECE can be achieved in a ferroelectric polymer.

Nanoclusters containing up to several hundred transition metal atoms can be understood as intermediates between mononuclear complexes and binary solid-state phases. In contrast to conventional nanoparticles, these species are precisely monodisperse, and therefore their molecular structures can be determined by single crystal X-ray analysis. The figure shows the packing of the [Ag344S124(StBu)96] clusters in their 3D crystal lattice.

Pentacene second layer grows with a twist (76 °) on the first layer, while the third and subsequent layers show commensurism with their respective underlayers. The preferred twisting of the second layer on the first layer gives rise to epitaxial and non-epitaxial domains which also reflect in the surface electrostatic potential measurements.
