180 MW demonstration of advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NOx) emissions from coal-fired boilers. Technical progress report, First quarter 1991
This project is being conducted at Gulf Power Company`s Plant Lansing Smith Unit 2 (LS-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 NOx combustion technologies on NOx emissions and boiler performance. The stepwise approach that is being used to evaluate the NOx control technologies requires three plant outages to successively install the test instrumentation and the different levels of the low NOx 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 NOx reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency. This quarterly update provides a description of the flow modeling study. This modeling effort centers on evaluating the in-furnace flow and mixing phenomena for the various low NOx firing systems being demonstrated at LS-2. Testing on the 1/12 scale model of the LS-2 boiler and the 1/6 scale model of the overfire air ductwork was completed. The test matrix included an analysis of the overfire air ductwork and three different boiler configurations. This report also contains results from the Phase 1 baseline tests. Data from the diagnostic, performance, and verification tests are presented. In addition, NOx emissions data and unit load profiles collected during long-term testing are reported. At the full load condition, the baseline NOx emission level at LS-2 is 0.62 lb/mBtu.
