Project Description

This research will provide a systematic evaluation of flameholding tendencies in various combustor fuel/air premixer passage geometries. This evaluation will be completed for different fuel types (including high hydrogen content [HHC] fuels) at operating conditions (temperature, pressure, etc.) typical of those encountered in industrial-scale turbines. The observations made relative to flameholding tendencies will be analyzed and used to develop design guides that can be used to infer when flameholding will occur as a function of the parameters studied.

The high pressures and temperatures required to simulate the environment of a premixing passage for a natural gas-fired gas turbine will be generated at the University of California, Irvine Combustion Lab high pressure facility. The facility is capable of generating a preheated airflow at temperatures up to 1200 degrees Fahrenheit, pressures exceeding ten atmospheres, and a maximum flow rate that exceeds three pounds per second. To provide the planned conditions, a modular test apparatus will be used.

Project Benefits

This project will focus on evaluating flameholding tendencies of various combustor premixer geometric features using high hydrogen content fuels. The development of design guides that accurately infer when flameholding will occur will lead to hydrogen combustor designs that produce fewer emissions at higher temperatures. Specifically, this project will evaluate flameholding of various fuels at high temperatures and pressures that are relevant to actual turbine conditions.
