Abstract

Abstract A liquid fuel atomizer is described which creates liquid pulses and gas pulses which are directed and timed to impact each other. The forces created during impact atomize the liquid fuel into droplets. Large and repeated atomizing forces can be thusly applied yielding fine atomization of even very high viscosity liquids. Applications of crossed pulse liquid atomizers to liquid fuel burner combustion systems are described.
