Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
78 words
THE METHOD OF PREPARING A LIQUID HYDROCARBON FOR COMBUSTION WHICH COMPRISES: BURNING FUEL AND AIR TO PRODUCE HOT PRODUCTS OF COMBUSTION, MIXING A SUPPLYING OF ADDITIONAL AIR WITH SAID PRODUCTS OF COMBUSTION, REGULATING THE SUPPLY OF FUEL TO MAINTAIN THE MIXTURE OF ADDITIONAL AIR AND PRODUCTS OF COMBUSTION AT A TEMPERATURE ABOVE THE TEMPERATURE OF VAPORIZATION OF SAID LIQUID HYDROCARBON, INJECTING LIIQUID HYDROCARBON INTO SAID HOT MIXTURE THEREBY THE VAPORIZE THE HYDROCARBON AND FORM A VAPOR-AIR MIXTURE, AND
Claim 2
Independent Claim

Claim 3
Dependent Claim
30 words
The method of claim 1 including measuring the temperature of the mixture of products of combustion and additional air and adjusting the supply of fuel in response to said temperature.
Claim 4
Dependent Claim
29 words
The method of claim 1 including burning a sample of said oil vapor-air mixture and adjusting the supply of air in response to a condition produced by said burning.
Claim 5
Dependent Claim
106 words
Apparatus for vaporizing a liquid hydrocarbon comprising means forming a combustion chamber, a burner firing into said chamber, a discharge from said chamber for products of combustion, means to supply fuel and air to said burner, means to measure the temperature of the products of combustion, means to supply air to mix with said products of combustion, the mixture flowing to a vaporization chamber, means to inject liquid hydrocarbon into said mixture in said vaporization chamber, means responsive to said temperature measuring means to adjust said fuel supply to said burner to maintain the temperature of said mixture above the vaporization temperature of said liquid hydrocarbon.
Claim 6
Dependent Claim
