Development and testing of industrial scale, coal fired combustion system: Phase 3, Progress report, July 1, 1995--September 30, 1995

PDF Version Also Available for Download.

Description

The primary objective of the present Phase 3 effort is to perform the final testing, at a 20 MMBtu/hr commercial scale, of an air cooled, slagging coal combustor for application to industrial steam boilers and power plants. The focus of the test effort is on combustor durability, automatic control of the combustor`s operation, and optimum environmental control of emissions inside the combustor. In connection with the latter, the goal is to achieve 0.4lb/MMBtu of SO{sub 2} emissions, 0.2 lb./MMBtu of NO{sub x}, emissions, and 0.02 lb. particulates/MMBtu. To meet the particulate goal a baghouse will be used to augment the ... continued below

Description

The primary objective of the present Phase 3 effort is to perform the final testing, at a 20 MMBtu/hr commercial scale, of an air cooled, slagging coal combustor for application to industrial steam boilers and power plants. The focus of the test effort is on combustor durability, automatic control of the combustor`s operation, and optimum environmental control of emissions inside the combustor. In connection with the latter, the goal is to achieve 0.4lb/MMBtu of SO{sub 2} emissions, 0.2 lb./MMBtu of NO{sub x}, emissions, and 0.02 lb. particulates/MMBtu. To meet the particulate goal a baghouse will be used to augment the slag retention in the combustor. The NO{sub x} emission goal will require a modest improvement over maximum reduction achieved to date in the combustor to a level of 0.26 lb. /MMBtu. To reach the SO{sub 2} emissions goal may require a combination of sorbent injection inside the combustor and sorbent injection inside the boiler, or stack. In the third quarter of calendar year 1995 work continued on task 5, ``Site Demonstration``, with emphasis on installation of the 20 MMBtu/hr combustor and auxiliary equipment at the Philadelphia test site. The task 5 effort involve testing the combustor over extended periods under conditions that fully simulate commercial operation and that meet the combustion and environmental specifications for this project. During the present quarterly reporting period, over 90% of the components needed to implement the initial 100 hours of testing were installed at the test site.
