Abstract

Abstract A system for blending and mixing a supplemental unconventional fuel or fuels with the regular fuel or fuels utilized by a fuel consuming device, such as an internal combustion engine, furnace or other device that uses conventional petroleum fuels which enables the owner or user of the fuel consuming device to utilize supplemental fuels. The system enables the owner or user of the fuel consuming device to control or adjust the quantity of supplemental fuel that is added to the fuel system of the device and enables the owner or user to operate the device selectively with or without using the supplemental fuel mixture. In order to enable the device that is consuming the supplemental fuel or fuels, blend of supplemental fuel or fuels and regular fuel or fuels or regular fuel or fuels there is a mechanism forming part of this invention to regulate the temperature to keep the temperature of the fuels consuming device within the desired operating range for the fuels consuming device. The mechanism to control the temperature of the fuels consuming device may add heat to or remove heat from the device when in operation. Also, there may be a need to add heat to or remove heat from the fuels that are consumed by the device in order to condition the fuels so that they are in a suitable state for use in the fuel consuming device. An oxidizing or purging agent can be used to remove deposits of either fuel or expended fuels from the fuel consuming device or system that is used to condition the fuels of the fuel consuming device.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 111 words
A system for selectively blending and mixing supplemental fuel or fuels with regular fuel for a fuel consuming device which includes a supply tank for regular fuel with a fuel line communicating directly with the fuel consuming device, a supply tank for supplemental fuel, fuel blender means, means selectively diverting regular fuel through the blender means prior to delivery to the fuel consuming device, and means selectively controlling flow or supplemental fuel to the blender means to enable a blended mixture of regular fuel and supplemental fuel to flow to the fuel consuming device and also enable only regular fuel or only supplemental fuel to flow to the fuel consuming device.
Claim 2
Independent Claim 111 words
A system for selectively blending and mixing supplemental fuel or fuels with regular fuel for a fuel consuming device which includes a supply tank for regular fuel with a fuel line communicating directly with the fuel consuming device, a supply tank for supplemental fuel, fuel blender means, means selectively diverting regular fuel through the blender means prior to delivery to the fuel consuming device, and means selectively controlling flow or supplemental fuel to the blender means to enable a blended mixture of regular fuel and supplemental fuel to flow to the fuel consuming device and also enable only regular fuel or only supplemental fuel to flow to the fuel consuming device.
Claim 3
Dependent Claim 40 words
The system as defined in claim 1 wherein said means controlling flow of supplemental fuel or fuels to the blender means includes a flow line with valve means therein adapted to be manually controlled or controlled by a programmed control.
Claim 4
Dependent Claim 75 words
The system as defined in claim 2 wherein said means diverting regular fuel through the blender means includes a bypass line communicated with the fuel line at spaced points, a valve in said fuel line between said spaced points, said blender means being incorporated in said bypass line, and control valves in said bypass line with one of said valves being upstream of the blender means and one valve being downstream of the blender means.
Claim 5
Dependent Claim 80 words
The system as defined in claim 3 together with a second supply tank for a second supplemental fuel, a supply line having a valve therein communicating said second supply tank with said blender means to selectively enable a controlled blended mixture of regular fuel and one supplemental fuel, regular fuel and two supplemental fuels, only regular fuel, only either of the supplemental fuels or only a controlled blended mixture of two supplemental fuels to flow to the fuel consuming device.
Claim 6
Dependent Claim 75 words
The system as defined in claim 4 together with a third supply tank for a third supplemental fuel, a supply line having a valve therein communicating said third supply tank with said blender means to selectively enable a controlled blended mixture of regular fuel and any one, any two or all three supplemental fuels, only regular fuel, and only any one, any two or all three supplemental fuels to flow to the fuel consuming device.
Claim 7
Dependent Claim 53 words
The system as defined in claim 5 together with a supply tank for an oxidizing or purging agent, and a valve controlled line communicating the oxidizing or purging agent supply tank with the fuel line downstream of the blender means to enable selective removal of residue or deposits from the fuel consuming device.
Claim 8
Dependent Claim 83 words
The system as defined in claim 6 together with heat exchange means associated with the fuel consuming device, a coolant supply line communicated with the heat exchange means, a valve in said coolant supply line for controlling the operating temperature thereof in accordance with the fuel being consumed, an air supply line communicating with the heat exchange means associated with the fuel consuming device, and a valve in said air supply line to control the exchange of heat in the heat exchange means.
