Crossed pulse burner atomizer

DETAILED DESCRIPTION The liquid atomizers of this invention comprise a liquid pulser means, a gas pulser means, a drive and timing means, and these positioned and timed so that each liquid pulse is impacted by a gas pulse moving across its path at least once and it is the pressure wave and the gas flow of the gas pulse which create the atomizing forces.
Preferably a gas pulse reflector means is also used and positioned to reflect the gas pulses back toward the liquid pulses so that each gas pulse impacts liquid pulses several times and so that each liquid pulse is impacted by gas pulses several times.
In this way strong atomizing forces can be created and repeatedly applied to the liquid without using high liquid velocities and hence without the necessity of large liquid penetration along the path of atomization.
This short path of atomization makes possible the use of high viscosity fuels in small piston diameter diesel engines, the necessary fine atomization of the liquid fuel being secured by the repeated gas pulse impacts upon the liquid pulses essentially at right angles to the penetration direction and this is one of the beneficial objects of this invention.
Each gas pulse can be efficiently utilized to atomize the liquid since it repeatedly impacts the liquid, and at each impact the reflected gas pulse is moving contrary to the liquid motion induced by atomization.
Hence, only small quantities of atomizing gas need be used to secure fine atomization in burners using high viscosity fuels and this is another beneficial object of this invention.
