Enhanced Gas CoFiring Experience at Orlando Utilities

摘要

With the implementation of MATS, the pending Clean Power Plan, depressed gas prices and an increasing emphasis on renewables, traditional coal-fired generating assets are looking for flexible solutions. Starting with the October 2012 outage, Stanton Energy Center began a long-range program to utilize increasing levels of natural gas in dual locations within Unit 1. High volume natural gas igniters replaced the existing oil-fired igniters in 2012 and Fuel Lean Gas Reburn for NOx reduction and upper-furnace use of natural gas was implemented in 2015. As the latest step in this program, Stanton is replacing two levels of the existing igniters with Breen's Dual-Orifice CoFiring igniters in 2016. This paper will document the environmental and performance results of each of those steps, the lessons learned during implementation, and project the long term impact of this combined coal/gas firing technology on long term compliance with MATS and CPP objectives.
