Summary
The objective of this program is to develop a topping combustor to operate in a Second-Generation Pressurized Fluidized Bed (PFBC) Combined Cycle power generation system. The combustor must be able to: lightoff with a high heating value fuel and compressor discharge air to heat the fluidized bed(s) and provide power for PFBC and carbonizer off-line; operate with 1,600 F oxygen depleted air from the PFBC and high heating value fuel to handle carbonizer off-line conditions; ramp up to 100% carbonizer syngas firing (normal operation) by firing a blend of decreasing high heating value fuel and increasing low heating value syngas; utilize the vitiated air, at temperatures up to 1,600 F for as much cooling of the metal combustor as possible, thus minimizing the compressor bypass air needed for combustor cooling; provide an acceptance exit temperature pattern at the desired burner outlet temperature (BOT); minimize the conversion of fuel bound nitrogen (FBN) present in the syngas to NOₓ; and have acceptably high combustion efficiency, and low emissions of carbon monoxide, UHC, etc. This paper reports the results of tests of a 14 inch diameter topping combustor with a modified fuel-rich zone conducted in June 1993, design of an 18 inch diameter topping combustor to be tested in June 1994 and afterwards, and results of a 50% scale cold flow model which has been built and tested.
