Book Description
The Clean Coal Technology Demo. Program (CCTDP) is an effort to demonstrate a new generation of innovative coal utilization processes in a series of facilities built across the country. These projects are carried out on a commercial scale to prove technical feasibility and provide the info. required for future applications. Projects have demonstrated technical options with the potential to meet the needs of energy markets while satisfying environ. requirements. Part of this program is the demo. of technologies designed to reduce emissions of oxides of nitrogen (NOx) from existing coal-fired utility boilers. This report summarizes the status of selective catalytic reduction (SCR) technology for the control of NOx emissions from high-sulfur, coal-fired boilers. Illus.

Book Description
This project is part of the U.S. Department of Energy's (DOE) Clean Coal Technology Demonstration Program (CCTDP) established to address energy and environmental concerns related to coal use. DOE sought cost-shared partnerships with industry through five nationally competed solicitations to accelerate commercialization of the most promising advanced coal-based power generation and pollution control technologies. The CCTDP, valued at over five billion dollars, has significantly leveraged federal funding by forging effective partnerships founded on sound principles. For every federal dollar invested, CCTDP participants have invested two dollars. These participants include utilities, technology developers, state governments, and research organizations. This project is one of 16 selected from 55 proposals submitted in response to the CCTDP's second solicitation. Southern Company Services, Inc. (Southern), a subsidiary of Southern Company, conducted the Demonstration of Selective Catalytic Reduction for the Control of NOx Emissions from High-Sulfur, Coal-Fired Boilers project. Gulf Power Company's Plant Crist provided the host site and the Electric Power Research Institute (EPRI) and Ontario Hydro co-funded the project and provided technical input. The project began in June 1990 and operational testing occurred between July 1993 and July 1995. In simplistic terms, the selective catalytic reduction (SCR) process consists of injecting ammonia (NH3) into boiler flue gas and passing the flue gas through a catalyst bed where the oxides of nitrogen (NOx) and NH3 react to form water vapor and nitrogen (an element that comprises 78 percent of air).

Book Description
The most efficient process to reduce NOx emissions from lean exhaust gases, selective catalytic reduction (SCR) with ammonia, has undergone tremendous development over the past decades. Originally only applied in stationary power plants and industrial installations, SCR systems are now installed in millions of mobile diesel engines, ranging from off-road machineries, to heavy-duty and light-duty trucks and passenger cars, to locomotives and ships. All of these applications involve specific challenges due to tighter emission limits, new internal combustion engine technologies, or alternative fuels. Three review articles and 14 research articles in this book describe recent results and research trends of various aspects of the SCR process. Reaction engineering aspects, such as the proper dosage of ammonia or urea, respectively, are as important as further developments of the different SCR catalysts, by deepening the understanding of their functionality or by systematic improvements of their properties, such as low-temperature activity, selectivity, or poisoning-resistance. Another covered aspect is cost reduction through the use of cheaper base materials for the production is active and stable SCR catalysts. Finally, research efforts are reported to develop SCR processes with different reducing agents, which would open doors to new applications in the future. The range of topics addressed in this book will stimulate the reader's interest as well as provide a valuable source of information for researchers in academia and industry.

Book Description
Environmentally oriented modernization of power boilers explains how to retrofit and upgrade power boilers in aging thermal and CHP plants, with emphasis on pulverized fuel boilers (PF). The work provides direct avenues to higher boiler efficiency, harmful emissions reduction, fuel grinding system modernization, fuel flexibility, boiler operation flexibilization, reduced corrosion, erosion, and fouling. It also explores how to integrate emission reduction systems into boiler operations. The work is planned for engineers and graduate students as well as for power plant management. For the latter, it helps find the best solution for the necessary modernization and functions as an aid in organizing tenders as well as in evaluating projects offered. Errata to published editions can be found here https://modernpowerboilers.org/errata.html Presents, in a clear and accessible way, the most important solutions related to boiler emissions reduction, including CO2 emissions Helps increase boiler efficiency through technical and operational upgrades Helps increase the usefulness of boilers by increasing fuel and operational flexibility Supports reduction of harmful phenomena, such as corrosion, erosion, and fouling Accompanied with a careful selection of realized modernizations, including pitfalls and best practice discussion Chapters are presented alongside hundreds of literature references for further study
