Abstract

Integrating a catalytic ignitor into a fuel injector offers an opportunity to significantly improve ignition and flame stability, producing a number of important benefits. Compared to conventional spark ignition systems, benefits using an air blast ingector will include easier starting, reduced soot and NOx emissions, improved pattern factor, ignition independent of fuel droplet size, longer ignitor and hot section component life, and a smaller, lighter and less expensive ignition system (with no high voltage requirement). Faster, leaner light off will produce cooler starts with less smoke and hot end distress. In addition, an integral catalytic ignitor/injector will isolate the ignition function from the combustor liner geometry. In the Phase I of this project, a prototype produced leaner ignition at low power with diesel fuel was achieved at the liner lean limit of a production liner and even leaner in a lean primary zone liner. Lean flame out was suppressed with the ignitor power on. In Phase II we propose to build on Phase I results to develop and test the technology for Army gas turbine engines. Two major aerospace component manufacturers will be providing collaborative assistance.
