Abstract
A method for atomizing a fluid wherein a gas is heated with the heating facilitating the acceleration of the gas to a high velocity. The accelerated gas contacts the fluid transferring shear, pressure and inertial forces and heat to the fluid effecting efficient atomization of the fluid.
Claims9
A method for atomizing an atomizable liquid comprising:
- (A) heating a gas to a temperature of at least 300° F. to produce a hot gas and flowing the hot gas in an annular passage coaxially with a flow of the atomizable liquid in a central tube;
- (B) thereafter passing the hot gas through an opening to produce an accelerated hot gas stream having a velocity within a range of from 1000 to 6000 feet per second;
- (C) contacting the accelerated hot gas stream with the flow of atomizable liquid;
- and
- (D) applying shear, pressure and inertial forces from the accelerated hot gas stream to the flow of atomizable liquid and causing at least some of the flow of atomizable liquid to break off from the flow and form droplets.
