Book excerpt: The U.S. Department of Energy (DOE)/Pittsburgh Energy Technology Center (PETC) and the Public Services Company of Colorado (PSCo) signed the cooperative agreement for the Integrated Dry NO(subscript x)/SO2 Emissions Control System in March 1991. This project integrates various combinations of five existing and emerging technologies onto a 100 MWe, down-fired, load-following unit that burns pulverized coal. The project is expected to achieve up to 70% reductions in both oxides of nitrogen (NO(subscript x)) and sulfur dioxide (SO2) emissions. Various combinations of low-NO(subscript x) burners (LNBs), overfire air (OFA) ports, selective non-catalytic reduction (SNCR), dry sorbent injection (DSI) using both calcium- and sodium-based reagents, and flue-gas humidification are expected to integrate synergistically and control both NO(subscript x) and SO2 emissions better than if each technology were used alone. For instance, ammonia emissions from the SNCR system are expected to reduce NO2 emissions and allow the DSI system (sodium-based reagents) to achieve higher removals of SO2. Unlike tangentially or wall-fired units, down-fired require substantial modification to their pressure parts to retrofit LNBs and OFA ports, substantially increasing the cost of retrofit. Conversely, the retrofitting of SNCR, DSI, or humidification systems does not require any major boiler modifications and are easily retrofitted to all boiler types. However, existing furnace geometry and flue-gas temperatures can limit their placement and effectiveness. In particular, SNCR requires injecting the SNCR chemicals into the furnace where the temperature is within a very narrow temperature range.

Book excerpt: The DOE sponsored Integrated Dry NO(subscript x)/SO2 Emissions Control System Program, is a Clean Coal Technology III demonstration, being conducted by Public Service Company of Colorado. The test site is Arapahoe Generating Station Unit 4, a 100 MWe, down-fired utility boiler burning a low-sulfur Western coal. The project goal is to demonstrate up to 70 percent reductions in NO(subscript x) and SO2 emissions through the integration of: (1) down-fired low NO(subscript x) burners with overfire air; (2) Selective Non-Catalytic Reduction (SNCR) for additional NO(subscript x) removal; and (3) Dry Sorbent Injection (DSI) and duct humidification for SO2 removal. This report documents the final phase of the test program, in which the overall performance of the integrated system was evaluated. Previous testing has shown that the goal of 70 percent NO(subscript x) removal was easily achieved with the combination of low-NO(subscript x) burners, overfire air, and urea-based SNCR. Similarly, the ability of the sodium-based DSI system to achieve 70 percent SO2 removal was also demonstrated previously. The integrated tests demonstrated the synergistic benefit of operating the SNCR and sodium-based DSI systems concurrently. With the automatic control system set to limit the NH3 emissions to less than 8 ppm, the NO2 emissions from the sodium-based DSI system were reduced by nominally 50 percent compared to operation with the DSI system alone. Comparably, the combined operation reduced NH3 emissions, as reflected by a higher urea injection rate for a fixed NH3 emission limit. With combined DSI and SNCR operation, an ammonia odor problem was encountered around the Unit 4 ash silo (this did not occur with the SNCR system operated alone at comparable NH3 slip levels). This odor problem is attributed to the sodium changing the rate at which NH3 is released from the ash when it is wetted for truck transport to the disposal site.

Book excerpt: The goal of the U.S. Department of Energy's (DOE) Clean Coal Technology (CCT) Program is to furnish the energy marketplace with a number of advanced, more efficient, and environmentally responsible coal utilization technologies through demonstration projects. These projects seek to establish the commercial feasibility of the most promising advanced coal technologies that have developed beyond the proof-of-concept stage. This document serves as a DOE post-project assessment (PPA) of a project selected in CCT Round III, the Integrated Dry NO(subscript x)/SO2 Emissions Control System (IDECS), as described in a Report to Congress (U.S. Department of Energy 1991). The desire to reduce emissions of nitrogen oxides (NO, nitric oxide, and NO2, nitrogen dioxide, collectively referred to as NO(subscript x)) and sulfur dioxide (SO2) by up to 70 percent at a minimum capital expenditure, while limiting waste production to dry solids that can be handled by conventional ash-removal equipment, prompted Public Service Company of Colorado (PSCC) to submit the proposal for the IDECS project. In March 1991, PSCC entered into a cooperative agreement with DOE to conduct the study. The project was sited at PSCC's Arapahoe Steam Electric Generating Station in Denver, Colorado. The purpose of this CCT project was to demonstrate the reduction of NO(subscript x) and SO2 emissions by installing a combination of existing and emerging technologies, which were expected to work synergistically to reduce emissions. The technologies were low-NO(subscript x) burners (LNBS), overfire air (OFA), and selective noncatalytic reduction (SNCR) for NO(subscript x) reduction; and dry sorbent injection (DSI), both with and without flue-gas humidification (FGH), for SO2 reduction. DOE provided 50 percent of the total project funding of $26.2 million.

Available in PDF, EPUB and Kindle. Book excerpt: It is a pleasure to present this volume consisting of a selection of papers presented at the 4th International Drying Symposium (IDS) held in Kyoto, July 9-12, 1984, under the sponsorship of the Society of Chemi cal Engineers, Japan. This book includes full texts of the ten keynote lectures and several papers which were presented in the technical sessions in the 4th IDS. As editors we had the arduous and unpleasant task of selecting papers for this volume. We were delighted with the high quality manuscripts sub mitted. We are grateful to the authors for their efforts in meeting the manuscript guidelines and also the deadlines. Aside from quality, we have attempted to maintain in this volume a balance of coverage in terms of topics as well as geography. Space restrictions prevented us from presenting all the high quality papers for publication in DRYING 85. Numerous papers of archival interest have been released for general publication in international journals. Several will no doubt appear in Drying Technology - An International Journal. Many others will find their way into other standard engineering journals as well. Over 120 papers from 30 countries were included in the Proceedings volumes distributed to all registrants in Kyoto. Numerous individuals, professional societies and organizations have contributed, directly or indirectly, to the success of the 4th IDS and hence to DRYING 85 as well. We wish to acknowledge in particular the monumental efforts of the Secretary of the 4th IDS, Professor M. Okazaki.
