Characteristics of n-butane weak flames at elevated pressures in a micro flow reactor with a controlled temperature profile

The very first successful experiments at elevated pressures up to 1.2 MPa by an “in-pressure-chamber”-type micro flow reactor with a controlled temperature profile are demonstrated. n-Butane was applied to the micro flow reactor and the ignition characteristics at pressures of 0.1–1.2 MPa were investigated by observing weak flames. Among three kinds of separated weak flames which can be observed by the present reactor, the blue flame was only...
