Development of Criteria for Flameholding Tendencies within Premixer Passages for High Hydrogen Content Fuels

Performer: University of California, Irvine

Project No: FE0007045

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.
