Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
168 words
A fuel burning apparatus including a burner, a primary fuel delivery system coupled to said burner and adapted to be connected to a source of primary fuel for delivery of primary fuel to said burner, a secondary fuel delivery system coupled to said primary fuel delivery system and adapted to be coupled to a source oF secondary fuel for delivering secondary fuel to said primary fuel delivery system, first selectively operable coupling means connected in said primary fuel delivery system and having an open state for permitting the flow of primary fuel and a closed state for preventing the same, second selectively operable coupling means coupled in said secondary fuel delivery system having an open state for permitting the flow of secondary fuel and a closed state for preventing the same, third means operatively associated with said first and second selectively operable means for preventing said second selectively operable means from being placed in its open state when said first selectively operable means is in its closed state.
Claim 2
Dependent Claim
168 words
A fuel burning apparatus including a burner, a primary fuel delivery system coupled to said burner and adapted to be connected to a source of primary fuel for delivery of primary fuel to said burner, a secondary fuel delivery system coupled to said primary fuel delivery system and adapted to be coupled to a source oF secondary fuel for delivering secondary fuel to said primary fuel delivery system, first selectively operable coupling means connected in said primary fuel delivery system and having an open state for permitting the flow of primary fuel and a closed state for preventing the same, second selectively operable coupling means coupled in said secondary fuel delivery system having an open state for permitting the flow of secondary fuel and a closed state for preventing the same, third means operatively associated with said first and second selectively operable means for preventing said second selectively operable means from being placed in its open state when said first selectively operable means is in its closed state.
Claim 3
Dependent Claim
71 words
The apparatus set forth in claim 1 including first flow regulating means in said primary fuel delivery system for regulating the flow rate of said primary fuel and second flow regulating means in said secondary fuel delivery system for regulating the flow rate of said secondary fuel, and fourth means operatively associated with said first and second flow regulating means for coordinating the flow rates of said primary and secondary fuel.
Claim 4
Dependent Claim
44 words
The apparatus set forth in claim 2 and including fifth means coupled to said fourth means and responsive to fuel demands for actuating said fourth means thereby to coordinate the flow rates of said primary and secondary fuels in accordance with said burner demands.
Claim 5
Dependent Claim
98 words
The apparatus set forth in claim 3 wherein said first and second flow regulating means include pressure responsive means, an air system for supplying combustion air to said burner, said air system also being coupled to the pressure responsive means of said first and second flow regulating means and to said fourth means, said fourth means being operative to regulate the pressure of said air system in accordance with burner conditions, changes in the pressure of said air system acting on said pressure responsive means being effective to modify the flow rate of said primary and secondary fuels.
Claim 6
Dependent Claim
94 words
The apparatus set forth in claim 4 wherein said secondary fuel delivery system includes pump means having an inlet coupled to receive secondary fuel and an outlet for delivering secondary fuel, pressure relief valve means coupled between the outlet of said pump and a return secondary fuel path, and first and second selectively operable valve means in said secondary fuel delivery system, said first selectively operative valve means being disposed adjacent the outlet of said pump, said second selectively operative valve means being disposed adjacent the connection between said primary and secondary fuel systems.
Claim 7
Dependent Claim
158 words
Fuel burning apparatus comprising a burner, a primary fuel delivery system coupled to said burner and adapted to be connected to a source of primary fuel for delivering primary fuel to said burner, a secondary fuel delivery system coupled to said primary fuel delivery system and adapted to be coupled to a source of secondary fuel for delivering secondary fuel to said primary system, first flow regulating means in said primary fuel delivery system for regulating the flow rate of said primary fuel, second flow regulating means coupled in said secondary fuel delivery system for regulating the flow rate of said second fuel, third means coupled to said first and second flow regulating means for simultaneously increasing or decreasing the flow rates of said primary and secondary fuels in accordance with burner fuel demands whereby the relative proportions of said primary and secondary fuels remains substantially constant as total fuel flow varies with variations in burner fuel demands.
Claim 8
Dependent Claim
158 words
Fuel burning apparatus comprising a burner, a primary fuel delivery system coupled to said burner and adapted to be connected to a source of primary fuel for delivering primary fuel to said burner, a secondary fuel delivery system coupled to said primary fuel delivery system and adapted to be coupled to a source of secondary fuel for delivering secondary fuel to said primary system, first flow regulating means in said primary fuel delivery system for regulating the flow rate of said primary fuel, second flow regulating means coupled in said secondary fuel delivery system for regulating the flow rate of said second fuel, third means coupled to said first and second flow regulating means for simultaneously increasing or decreasing the flow rates of said primary and secondary fuels in accordance with burner fuel demands whereby the relative proportions of said primary and secondary fuels remains substantially constant as total fuel flow varies with variations in burner fuel demands.
Claim 9
Dependent Claim
72 words
The apparatus set forth in claim 6 and including fourth means coupled to said third means and responsive to burner fuel demands for actuating said third means to simultaneously adjust the flow rates of said primary and secondary fuels in accordance with said burner fuel demands whereby the flow rates of both said primary and sEcondary fuels will both be increased or decreased in relation to burner fuel demands increase or decrease.
Claim 10
Dependent Claim
98 words
The apparatus set forth in claim 7 wherein said first and second flow regulating means include pressure responsive means, an air system for supplying combustion air to said burner, said air system also being coupled to the pressure responsive means of said first and second flow regulating means and to said fourth means, said fourth means being operative to regulate the pressure of said air system in accordance with burner conditions, changes in the pressure of said air system acting on said pressure responsive means being effective to modify the flow rate of said primary and secondary fuels.
Claim 11
Dependent Claim
91 words
The apparatus set forth in claim 8 whereby said secondary fuel system includes pump means having an inlet coupled to receive secondary fuel and an outlet for delivering secondary fuel, pressure relief valve means coupled between the outlet of said pump and a return secondary fuel path, and first and second selectively operable valve means in said secondary system, said first selectively operative valve means being disposed adjacent the outlet of said pump, said second selectively operative valve means being disposed adjacent the connection between said primary and secondary fuel systems.
Claim 12
Independent Claim
138 words
A method of incinerating waste fluid comprising the steps of: providing a primary fuel to a combustion device for burning the same, regulating the flow rate of said primary fuel to said burner, injecting the waste fluid to be incinerated into the stream of primary fuel, regulating the flow rate of said waste fluid, reducing the quantity of primary fuel provided to said burner in accordance with the quantity of waste fluid being injected into said fuel stream, mixing said primary fuel and waste fluid, providing said mixture to said burner, determining fuel requirements of said burner and proportionately adjusting the flow rates of both said primary fuel and waste fluid in accordance with increases or decreases in burner fuel requirements whereby the proportions of said primary and secondary fuels remain substantially constant as total fuel requirements vary.
Claim 13
Independent Claim
138 words
