Reducing Emissions to Mitigate Global Environmental Concerns GE’s Steam Power Systems is an industry leader in cleaner power generation from coal and oil. Stringent regulations to limit emissions have been deployed, revised and reinforced for decades. The U.S. and parts of Europe have strict emission regulations in place, while China has implemented, and India is developing, environmental control strategies to cope with booming development of their coal-based industries. With more than 80 years of experience providing Air Quality Control Systems (AQCS), GE has the expertise, technology and extended product portfolio to reduce gaseous emissions from coal (or oil) combustion and meet today’s most stringent emission requirements. To reduce CO2 emissions, GE is contributing on two major fronts. First, GE has designed, installed and commissioned many of the highest efficiency coal and oil plants in the world, which not only optimize the operating costs (reduced fuel consumption per MW produced) but also reduce the CO2 emitted per MW produced. Second, GE has developed and industrially tested CO2 Capture solutions which are fully ready for large-scale deployment.

BOILERS Portfolio and Overview Tangential Firing System
Industry Leader in Supercritical and High Efficiency
GE introduced the tangential firing system in 1927. Fuel and air are injected through windboxes from the corners of the furnace, aimed tangent to an imaginary circle in the center of the furnace. This creates a single rotating flame envelope (vortex) that produces a uniform and consistent heat profile across the furnace walls over the operating load range. Due to aerodynamics, the fuel and air are mixed throughout the furnace, resulting in high efficiency combustion. Tangential firing also provides the following advantages for GE’s two-pass and tower boiler designs:
GE led the industry in developing supercritical steam generation technology, and is an industry leader in today’s high efficiency ultra-supercritical technology. Our expertise in thermal, hydraulic, and material sciences has led to boiler designs that offer tremendous improvements in steam parameters. Advanced tangential firing systems can lower exhaust gas emissions, providing an additional benefit as countries seek to lower emissions.
• Low primary NOx emissions for decreased SCR catalyst volume, reagent use, and maintenance requirements • Efficient use of furnace volume, resulting in reduced slagging tendency and soot-blowing frequency
High Efficiency
GE’s ultra-supercritical boilers contribute to cycle efficiencies of 42 to 45 percent on an HHV basis (44 to 47 percent LHV basis), significantly reducing both fuel and emission control costs for our customers.
Extensive Experience and Reference
To date, GE has directly supplied more than 116,000 MW of supercritical/ultra supercritical boilers worldwide, and has licensed and trained other companies to install an additional 140,000 MW.
• Excellent flame stability for increased unit turndown and a wider latitude for fuel property variation
Continuous Development
• Tilting capability resulting in no attemperation for reheat temperature controls
•U ltra-supercritical circulating fluidized bed (USC CFB): With our world-class experience in ultra-supercritical pulverized coal boilers and expertise in the design of CFB firing, GE has developed highly efficient ultra-supercritical CFB technology, which provides reliable and fuel-flexible power generation with a lower CO2 footprint.
GE continues to invest significantly in research and development dedicated to improving our high efficiency power generation equipment.
• Double reheat (DRH): GE has supplied double reheat boilers for more than 50 years, and today we offer USC double reheat configurations for both tower and two-pass boiler designs. • Advanced ultra-supercritical (A-USC): GE is in collaboration with various groups in Europe (700°C) and the U.S. (760°C) for A-USC steam cycle development.

TWO-PASS BOILERS
Furnace and Convective Passes, Tilting Tangential Firing System, Experience Firing Fuels from All Over the Globe
GE’s two-pass boiler is the workhorse of the power industry, generating steam for today’s large-scale global power projects (up to 1,350 MWe) at pressures and temperatures that can reach the service limits of contemporary materials. Radiant pendant surfaces are located above the furnace, and convective surfaces are arranged horizontally in the second pass. The two-pass configuration results in an efficient furnace height and a lower cost of construction. Our patented tilting tangential firing system accommodates the large spectrum of fuels found across the globe (multiple grades of coal, oil, gas, heavy residues, biomass and other opportunity fuels), and is a leader in primary emissions control.

CFB BOILERS Combination of Fuel Flexibility and Low Emissions
During the past two decades, circulating fluidized bed (CFB) technology has demonstrated its ability to efficiently utilize a wide variety of fuels – including fuels with high ash, high moisture, high sulfur, low volatiles, and low heating value that are unsuitable for other firing systems – while meeting stringent stack emission limits. This unique combination of fuel flexibility and low emissions has led to the development and growth of CFB technology in power generation. • Efficient Combustion A wide range of fuels can be burned efficiently, including low-grade and difficult-to-burn fuels such as anthracite, lignite, petroleum coke, oil shale, discarded coal and biomass. • Fuel Flexibility Several different fuels can be fired in the same boiler within a wide range of mixing rates. • Low inherent NOx emissions at 50-200 mg/Nm3 —R elatively low and uniform furnace temperatures of approximately 850°C to 900°C — Air staging in the lower furnace through the introduction of primary air and secondary air at appropriate levels —U niformly distributed fuel and air due to intense mixing inside the bed of solids in the furnace — Isothermal conditions in the circulating solid loop due to the positive impact of highly efficient cyclones — Selective non-catalytic reduction (SNCR) systems can be added, leading to even lower NOx emissions • Low SO2 emissions with 95 to 98 percent sulfur removal — Injection of prepared and dried limestone in the furnace — Potentially inherent capture by the fuel-bound calcium — Dry scrubber NID* achieving 98 percent sulfur removal while reducing limestone consumption — Just-In-Time (JIT*) system for limestone drying and crushing available for direct limestone feeding

Tubes in Stainless Steel for Stator-Winding Cooling Used on GIGATOP 2-pole generator • The cooling tubes in the stator winding of GE’s GIGATOP 2-pole generator are made of stainless steel, so they can’t corrode, and the risk of clogging leading to an unplanned forced outage is eliminated. GE is the only manufacturer to offer this feature. Self-Retightening End-Winding Support Used on TOPAIR, TOPGAS and GIGATOP 2-pole generators
Power Output Range (MW)
GIGATOP 2-pole Hydrogen-water-cooled
GE’s generators are designed to meet all relevant standards, regulations and grid codes that may apply in specific 50 Hz and 60 Hz countries. Machines are designed according to IEC and IEEE standards and are designed for temperature rises of class 130 (B). The insulation, using either DURITENAX or MICADUR* tape (depending on the product family), fulfills thermal class 155 (F). We perform quality tests and inspections during manufacturing, delivery, construction and commissioning of the machines to help ensure high quality and conformance with our customers’ needs.
• GE’s generators have a self-retightening end-winding support, which allows thermal expansion of the bars while simultaneously tightening the winding in radial and tangential directions. This system saves maintenance time for the generator end user, avoids forced outages, and increases plant availability on the grid. Concave-Convex Wedges Used on TOPAIR, TOPGAS and GIGATOP 2-pole generators • The concave-convex wedges used in GE’s generators have a unique design that sustains pressure on the stator bars. This constant pressure prevents radial movements of the winding, avoiding a forced outage from insulation breakdown while cutting maintenance hours and increasing plant availability.

Today’s TOPGAS generator power output range goes beyond 710 MVA (ca. 600 MW), so the generator can be installed in power plants that generally would require more complex hydrogen-water-cooled generators, such as conventional 660 MW coal power plants. By offering a lower investment cost and higher efficiency than conventional hydrogen-water-cooled generators, the TOPGAS generator reduces electricity costs and emissions.
Features • L ower investment cost, derived from the high power rating and the generator’s efficiency. TOPGAS machines are a cost-effective alternative to more complex hydrogenwater-cooled generators that normally are used for similar power output levels •E xcellent 99.7 percent reliability, based on measurements collected from 34 TOPGAS units between 1998 and 2012

The most powerful air-cooled generator in operation today, GE’s TOPAIR unit has accumulated worldwide operational experience from more than 570 installations. It is a robust machine providing high reliability and maintainability. TOPAIR air-cooled generators have a power output range that usually is found in larger and less cost-effective hydrogen-cooled generators. This is the result of continuous, evolutionary development that has pushed the limits of power output while enhancing efficiency and controlling investment costs. At the same time, it is simple and easy to operate and maintain. The flexible TOPAIR, because of its short production time (parallel manufacture of stator and casing, pre-assembly, and ease of transport), is a generator that can be up and running quickly. This reduces construction and commissioning time and accelerates plant revenue flow. TOPAIR units are available in standardized sizes, with different capabilities and performances.

CAP features include:
CO2 Absorption Flue Gas Cooling/ conditioning
CO2 Regeneration
• High CO2 product purity • CO2 capture process tolerant to oxygen and flue gas impurities • Stable reagent, no degradation or emission of trace contaminants
CAP
• Low-cost, globally available reagent
Parameters
• Ability to use low ambient conditions to further reduce the energy consumption of the process
Flue Gas Inlet Conditions
• Integrated approach from GE, providing both economic and technical benefits

Environmentally benign in terms of emissions, CAP is a chemical absorption process using an ammonium-based aqueous solvent. The flue gas is contacted with chemical solvent – forming ammonium bicarbonate, ammonium carbonate and ammonium carbamate. The chemical reactions are reversible, and raising the temperature and the pressure of the reaction products reverses the capture reactions, releasing CO2 and allowing the solvent to be regenerated and returned to the process.

The flue gas is bound with the chemical solvent – Advanced Amine – which binds selectively to the flue gas CO2. Raising the temperature reverses the capture reaction, releasing CO2 and allowing the solvent to be recycled. The technology has been demonstrated successfully in the field at 90 percent capture rates. Based on the low physical solubility of N2 and O2 in aqueous amines, CO2 product purity is greater than 99.5 percent after CO2 compression and dehydration. The highly selective reaction with CO2 is an important advantage of any alkaline scrubbing process and distinguishes this process from the results obtained from physical solvents, membranes or adsorbents.
