Gas Turbine Efficiency PLC (GTE) is using its experience in water injection and power augmentation to assist energy industry clients by installation of a universal system to help meet more stringent regulatory requirements in NOx emission limits. A recent GTE case study shows how one power generation customer successfully installed a single skid that incorporated both the water injection and power augmentation systems on their two GE MS50001Ps and three P&W FT4A engines. The combined system is capable of interfacing with virtually any control system and gas turbine fuel system. With this enhancement, the energy producer would provide cleaner and lower level emissions while increasing output and optimizing performance.
Wärtsilä and ABB Turbo Systems are cooperating to develop a two-stage turbocharging of large diesel engines. The companies say the technology offers significant advantages in fuel consumption and engine emissions. Wärtsilä is focusing on developing advanced engine technology, and ABB Turbo Systems is delivering turbocharging technology aimed at improving performance in terms of airflow, pressure ratios and efficiency. In the new engine design, two turbochargers are arranged in series to generate increased air pressure, airflow and a superior turbocharging effect. This results in an efficiency rating of up to 76 percent, according to the companies. The increased air pressure, combined with the advanced engine technology, is expected to improve the engine output and power density by up to 10 percent, while reducing both fuel consumption and CO 2 emissions.
Powerspan Corp. announced results from an independent review of its ECO2 post-combustion carbon dioxide (CO 2) capture technology, conducted by engineering firm WorleyParsons Group. WorleyParsons assessed Powerspan’s CO 2 capture pilot test facility and evaluated readiness for commercial deployment on existing coal-fired power plants. Powerspan’s post-combustion CO2 capture process uses a proprietary solvent to capture 90 percent of CO 2 from the flue gas of coal-fired plants. Once the CO 2 is captured, it is dried and compressed and is ready for pipeline transport and sequestration. The WorleyParsons report concludes that the 1 MW equivalent slipstream ECO2 pilot test facility (approximately 20 tons per day of CO2 capture) operating at FirstEnergy Generation Corp.’s R.E. Burger Plant near Shadyside, Ohio, gave testing results that can be reliably used to design, build, and predict performance of a larger, commercial size plant. The report concludes that a retrofit project could be implemented at less than $40 per ton of CO 2 captured and compressed for a project size of 220 MWe net. The cost estimate is based on data derived from the ECO2 pilot for 90-percent CO 2 capture with steam extraction for regeneration of less than 1,000 Btu/lb of CO 2. This energy requirement is an improvement over previously reported results.
MISTRAS Group Inc. developed and delivered a non-invasive coal flow monitoring system that with remedial action, can significantly reduce out-of-compliance events, and resulting EPA fines. The system detects blockages and imbalances in the
