Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
76 words
A method for controlling the combustion in a liquid fuel burner of the type utilizing a liquid fuel atomizer comprising a hollow horn which is oscillated at an ultrasonic frequency and includes a nozzle, said method comprising the step of supplying kerosene to a nozzle having a ratio of the area of the end surface of said nozzle to the area of the nozzle opening of 4.5 to 9, thereby controlling the liquid fuel atomization conditions.
Claim 2
Independent Claim
