Abstract

A pulse-fired burner is operated by modulating a fuel supply rate between a pilot level and a main level to provide a flame the level of which modulates respectively between a pilot level during a non-firing phase and a main flame level during a firing phase. Air supplied at a pilot rate is premixed with the fuel before ignition, the pilot air level being sufficient to support combustion of the fuel at the pilot rate but not at the main rate. The supply of fuel is terminated if no flame is sensed.
