Title: A Sensor System Based on Semi-Conductor Metal Oxide Technology for In Situ Detection of Coal Fired Combustion Gases

Abstract

Sensor Research and Development Corporation (SRD) proposed a two-phase program to develop a robust, autonomous prototype analyzer for in situ, real-time detection, identification, and measurement of coal-fired combustion gases and perform field-testing at an approved power generation facility. SRD developed and selected sensor materials showing selective responses to carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide, ammonia, sulfur dioxide and hydrogen chloride. Sensor support electronics were also developed to enable prototype to function in elevated temperatures without any issues. Field-testing at DOE approved facility showed the ability of the prototype to detect and estimate the concentration of combustion by-products accurately with relatively low false-alarm rates at very fast sampling intervals.

  • In December 1987, Public Law No. 100-202, as amended by Public Law No. 100-446, provided $575 million to conduct cost-shared Innovative Clean Coal Technology (ICCT) projects to demonstrate emerging clean coal technologies that are capable of retrofitting or repowering existing facilities. One of the selected proposals is the Southern Company Services, Inc's (SCS) proposal to demonstrate advanced tangentially-fired combustion techniques in a 180 MWe power plant. It will demonstrate the reduction of NO{sub x} emissions from pulverized coal-fired boilers by the use of three combustion control techniques; the Low NO{sub x} Concentric Firing System (LNCFS), Advanced Overfire Air (AOFA), andmore » the Combustion Engineering (CE) Concentric Clustered Tangential Firing System (CCTFS). AOFA involves improving the mixing of overfire air with the furnace gases to achieve complete combustion, and the depletion of air from the burner zone to minimize NO{sub x} formation. This technique is estimated to reduce NO{sub x} in tangentially-fired boilers by about 30%. 9 figs., 1 tab.« less
  • This quarterly report discusses the technical progress of a US Department of Energy (DOE) Innovative Clean Coal Technology (ICCT) Project demonstrating advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO[sub x]) emissions from a coal-fired boiler. The project is being conducted at Gulf Power Company's Plant Lansing Smith Unit 2 located near Panama City, Florida. The primary objective of this demonstration is to determine the long-term effects of commercially available tangentially-fired low NO[sub x] combustion technologies on NO[sub x] emissions and boiler performance. A target of achieving fifty percent NO[sub x] reduction using combustion modifications has been establishedmore » for the project. The stepwise approach that is being used to evaluate the NO[sub x] control technologies requires three plant outages to successively install the test instrumentation and the different levels of the low NO[sub x] concentric firing system (LNCFS). Following each outage, a series of four groups of tests are performed. These are (1) diagnostic, (2) performance, (3) long-term, and (4) verification. These tests are used to quantify the NO[sub x] reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency. This technical progress report presents the LNCFS Level I short-term data collected during this quarter. In addition, a comparison of all the long-term emissions data that have been collected to date is included.« less
  • This quarterly report discusses the technical progress of an Innovative Clean Coal Technology (ICCT) demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (No[sub x]) emissions from coal-fired boilers. The project is being conducted at Georgia Power Company's Plant Hammond Unit 4 located near Rome, Georgia. The primary goal of this project is the characterization of the low NO[sub x] combustion equipment through the collection and analysis of long-term emissions data. A target of achieving fifty percent NO[sub x] reduction using combustion modifications has been established for the project. The project provides a stepwise retrofit of anmore » advanced overfire air (AOFA) system followed by low NO[sub x] burners (LNB). During each test phase of the project, diagnostic, performance, long-term, and verification testing will be performed. These tests are used to quantify the NO[sub x] reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency.« less

This technical progess report presents the LNCFS Level III long-term data collected during this quarter. NO[sub x] emissions for each day of long-term testing are presented. The average NO[sub x] emission during long-term testing was 0.39 lb/MBtu at an average load of 155 MW. The effect of the low NO[sub x] combustion system on other combustion parameters such as carbon monoxide, excess oxygen level, and carbon carryover are also included.« less
