Development of Criteria for Flashback Propensity in Jet Flames for High Hydrogen Content and Natural Gas Type Fuels

Project Description

The goal of this University of California, Irvine project is to develop design guides that can be used to predict jet flame flashback propensity as a function of pressure, temperature, fuel composition, free stream velocity, turbulence level, and fuel-air mixing profiles. This effort will lead to a better fundamental understanding of flashback tendencies and will also provide insight into strategies for preventing flashback.

Completed Test Apparatus


Program Background and Project Benefits

This project will develop design guides to predict flame flashback propensity for high hydrogen content fuels. A better fundamental understanding of flashback tendencies will also provide insight into strategies for preventing flashback when designing hydrogen combustors that operated with fewer emissions at higher temperatures. Specifically, this project will conduct experimental studies of jet flame flashback using a test facility designed to investigate flashback at gas turbine relevant conditions and correlating the results to local flow and injector tip conditions.
