This book was released on 2013 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing concerns about freshwater availability increase the pressure on power plant to reduce water usages. The Innovations for Existing Plants Program from the US Department of Energy's National Energy Technology Laboratory is developing technologies in 5 categories to reduce water use. One of them is reclaiming water from combustion flue gas for usage as cooling water make-up. Considering that heat transfer efficiency is significantly enhanced in both gas and liquid phases due to corona wind and wetted wall inside the wet ESPs, a innovative technology of applying air-cooled condensing wet ESP for water recovery from flue gas was proposed. Additionally, the preliminary results show that the quantities of water extracted by the proposed air-cooled condensing wet ESP far exceed the FGD water make-up. However, the optimization of wet ESP's fin configuration is at an early stage, and the operation condition effects on the determination of optimal fin's configuration are not investigated yet. Thus, in this research, an analytical model of heat process in air-cooled condensing wet ESP system was developed to predict the heat transferred from flue gas to cooling air and the condensation rate of water vapor in the flue gas. Optimum fin's thickness and spacing under the operation conditions of ̊80°F ambient temperature and 5MW fan power were evaluated. In addition, the effects of fan power and ambient temperature on the determination of optimal fin's configuration and water recovery are investigated. It is found that the optimal fin's thickness is 0.25 inches, and the optimal fin's spacing is 0.5 inches with 5MW fan power, and outside cooling air temperature of ̊80°F. Under these optimized parameters, the total amount of water recovery reaches 557.725 gpm. Furthermore, changing ambient temperature has no effects on optimal fin's configuration, while increasing fan power make the optimal fin's thickness and spacing shift to lower value.

This book was released on 2013 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater availability has become a major concern in some areas of the United States where continuous droughts and ground water depletions are evident. Furthermore, it is in most of those areas where population growth is being experienced in a faster rate, which results in increases in service demands including electricity and water. In view of this, the thermoelectric generating capacity is expected to increase creating a higher demand of water volumes for the operation of their cooling systems. It is expected that thermoelectric power plants will start competing for freshwater with other sectors. The main objective of this study is to estimate the water footprint of coal-fired power plants and to investigate water-saving approaches available within the cooling and steam generation technologies, with a major emphasis on the facilities located in the regions of U.S. with the highest water limitations. Also, the heat transfer optimization of an air-cooled condenser wet electrostatic precipitator (ESP) for the water recovery from coal power plant's flue gas was performed. The states found to be experiencing the highest levels of water scarcity in the U.S. are California, Nevada, Arizona, New Mexico, Utah, and Texas. The results indicate that for once-through cooling systems and recirculating cooling systems located in the Southwest, the water footprints are 4.31E-04 and 5.75E-04 m3/MJ, respectively. It was observed that water withdrawals are higher on once-through systems than in recirculating systems, but the total water consumption is just slightly lower, resulting in a water footprint very similar for both types of system operating in the same region. Furthermore, it was shown that the use of an air-cooled condenser wet ESP represents a potential solution for the recovery of water from coal power plants' flue gas, especially those located in water stressed states.

Available in PDF, EPUB and Kindle. Book excerpt: The reader receives information on electrical gas cleaning systems as they are operated in power plants, steel works, cement works, chemical plants, CHP plants and biomass power plants. Electrostatic precipitators clean gases, especially exhaust gases, from dust and aerosols down to the smallest particle sizes. With reference to practice, the book explains the physical, constructive and electrotechnical basics. It also describes the requirements for the design and operation of these systems. The current edition deals in particular with the physics of negative and positive corona and the extended application possibilities that arise from the targeted use of positive corona. A number of references show ways to calculate and cost-effectively build a new electrostatic precipitator - or to upgrade or convert an existing one for lower clean gas values.

Available in PDF, EPUB and Kindle. Book excerpt: The new waste heat and water recovery technology based on a nanoporous ceramic membrane vapor separation mechanism has been developed for power plant flue gas application. The recovered water vapor and its latent heat from the flue gas can increase the power plant boiler efficiency and reduce water consumption. This report describes the development of the Transport Membrane Condenser (TMC) technology in details for power plant flue gas application. The two-stage TMC design can achieve maximum heat and water recovery based on practical power plant flue gas and cooling water stream conditions. And the report includes: Two-stage TMC water and heat recovery system design based on potential host power plant coal fired flue gas conditions; Membrane performance optimization process based on the flue gas conditions, heat sink conditions, and water and heat transport rate requirement; Pilot-Scale Unit design, fabrication and performance validation test results. Laboratory test results showed the TMC system can exact significant amount of vapor and heat from the flue gases. The recovered water has been tested and proved of good quality, and the impact of SO2 in the flue gas on the membrane has been evaluated. The TMC pilot-scale system has been field tested with a slip stream of flue gas in a power plant to prove its long term real world operation performance. A TMC scale-up design approach has been investigated and an economic analysis of applying the technology has been performed.
