Abstract
Abstract The present invention relates to apparatus for incinerating combustible wastes wherein a pilot light for igniting the wastes is provided at a location remote from a source of fuel for said pilot light. By the present invention, a pilot light burner is provided at the remote location and a fuel jet-ejector for producing a combustible mixture of fuel and air is provided at the location of the source of fuel. A first conduit connects the fuel-air mixture discharge connection of the jet-ejector to the pilot light burner and a second conduit connects the source of fuel to the fuel inlet connection of the jet-ejector. A third conduit is provided connected to the second conduit and to the pilot light burner for conducting fuel directly to the burner separately from the fuel-air mixture conducted thereto by way of the first conduit.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
154 words
Apparatus for incinerating combustible wastes comprising: a flare stack connected to the source of said combustible wastes; a pilot flame burner attached to said flare stack and positioned with respect thereto so that combustible wastes discharged therefrom are ignited by said pilot flame; a first conduit attached to said pilot flame burner for continuously conducting fuel and air to said burner; a fuel jet-ejector for producing a continuous stream of a combustible mixture of fuel and air having a fuel inlet connection, an air inlet connection and a fuel-air mixture discharge connection, said discharge connection being connected to said first conduit; a second conduit connecting the fuel inlet connection of said fuel jet-ejector to a source of fuel; and a third conduit connected to said second conduit and to said pilot flame burner for conducting a continuous stream of fuel to said burner separately from the fuel-air mixture conducted thereto by said first conduit.
Claim 2
Dependent Claim
154 words
Apparatus for incinerating combustible wastes comprising: a flare stack connected to the source of said combustible wastes; a pilot flame burner attached to said flare stack and positioned with respect thereto so that combustible wastes discharged therefrom are ignited by said pilot flame; a first conduit attached to said pilot flame burner for continuously conducting fuel and air to said burner; a fuel jet-ejector for producing a continuous stream of a combustible mixture of fuel and air having a fuel inlet connection, an air inlet connection and a fuel-air mixture discharge connection, said discharge connection being connected to said first conduit; a second conduit connecting the fuel inlet connection of said fuel jet-ejector to a source of fuel; and a third conduit connected to said second conduit and to said pilot flame burner for conducting a continuous stream of fuel to said burner separately from the fuel-air mixture conducted thereto by said first conduit.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1 which is further characterized to include valve means disposed in the third conduit for controlling the rate of fuel flowing therethrough to said pilot flame burner.
Claim 4
Dependent Claim
35 words
The apparatus of claim 2 which is further characterized to include valve means disposed in said second conduit for controlling the rate of fuel flowing therethrough to the fuel inlet connection of said fuel jet-ejector.
Claim 5
Dependent Claim
30 words
The apparatus of claim 3 which is further characterized to include ignition means disposed in said first conduit for igniting the fuel-air mixture flowing therethrough to said pilot flame burner.
Claim 6
Dependent Claim
28 words
The apparatus of claim 4 which is further characterized to include means attached to said pilot flame burner for detecting the presence of fuel combustion at said burner.
Claim 7
Dependent Claim
66 words
The apparatus of claim 5 which is further characterized to include valve means disposed in said second conduit operably connected to said means for detecting the presence of fuel combustion at said pilot flame burner so that the flow of fuel to said jet-ejector and to said third conduit is shut off when combustion at said pilot light burner is not detected by said detection means.
Claim 8
Dependent Claim
137 words
Apparatus for providing a pilot light at a location remote from a source of fuel which comprises: a pilot light burner positioned at said remote location; a fuel jet-ejector for producing a continuous stream of a combustible mixture of fuel and air positioned at the location of said source of fuel, said jet-ejector having a fuel inlet connection, an air inlet connection and a fuel-air mixture discharge connection; a first conduit connecting the fuel-air mixture discharge connection of said jet-ejector to said pilot light burner; a second conduit connecting said source of fuel to the fuel inlet connection of said jet-ejector; and a third conduit connected to said second conduit and to said pilot light burner for conducting a continuous stream of fuel to said burner separately from the fuel-air mixture conducted thereto by said first conduit.
Claim 9
Dependent Claim
137 words
Apparatus for providing a pilot light at a location remote from a source of fuel which comprises: a pilot light burner positioned at said remote location; a fuel jet-ejector for producing a continuous stream of a combustible mixture of fuel and air positioned at the location of said source of fuel, said jet-ejector having a fuel inlet connection, an air inlet connection and a fuel-air mixture discharge connection; a first conduit connecting the fuel-air mixture discharge connection of said jet-ejector to said pilot light burner; a second conduit connecting said source of fuel to the fuel inlet connection of said jet-ejector; and a third conduit connected to said second conduit and to said pilot light burner for conducting a continuous stream of fuel to said burner separately from the fuel-air mixture conducted thereto by said first conduit.
Claim 10
Dependent Claim
31 words
The apparatus of claim 7 which is further characterized to include valve means disposed in the third conduit for controlling the rate of fuel flowing therethrough to said pilot light burner.
Claim 11
Dependent Claim
35 words
The apparatus of claim 8 which is further characterized to include valve means disposed in said second conduit for controlling the rate of fuel flowing therethrough to the fuel inlet connection of said fuel jet-ejector.
Claim 12
Dependent Claim
30 words
The apparatus of claim 9 which is further characterized to include ignition means disposed in said first conduit for igniting the fuel-air mixture flowing therethrough to said pilot light burner.
Claim 13
Dependent Claim
28 words
The apparatus of claim 10 which is further characterized to include means attached to said pilot light burner for detecting the presence of fuel combustion at said burner.
Claim 14
Dependent Claim
67 words
The apparatus of claim 11 which is further characterized to include valve means disposed in said second conduit and operably connected to said means for detecting the presence of fuel combustion at said pilot light burner so that the flow of fuel to said jet-ejector and to said third conduit is shut off when combustion at said pilot light burner is not detected by said detecting means.
