TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: (I) further comprises: an intake receptacle having a coarse filter; an intake tank, where the receptacle and tank comprise a dumpster for fuel-laden waste; an inverter providing interconnection to a local electrical power distribution grid; a fuel heat exchanger in communication with or integrated with the fuel-warming system, where the fuel heat exchanger provides self-cleaning of waste-recovered fuel polymers from within the fuel heat exchanger; an exhaust bypass adapted to divert engine exhaust around the fuel heat exchanger and maintain the temperature of waste-recovered fuel exiting the heat exchanger at 212-275 degrees F; a secondary fuel tank adapted to heat waste-recovered fuel within the tank by a secondary source of energy other than thermal energy from engine combustion products; a solids processing unit adapted to transform waste organic solids into a fuel which is combustible by the internal combustion engine; a solids processing unit adapted to utilize thermal energy from engine combustion products to transform waste organic solids into liquid organic compounds; automated control apparatus adapted to start and run the engine periodically during periods when the ambient temperature is less than 20 degrees F; automated control apparatus adapted to start the engine after receiving an amount of waste-recovered fuel that exceeds a first threshold value and stop the engine when the amount of waste-recovered fuel falls below a second threshold value; and automated control apparatus adapted to deactivate the system during noise-sensitive hours, and reactivate the system at the expiration of noise-sensitive hours. In (I), waste-recovered fuel within the intake tank is in thermal communication with the fuel-warming system. The intake tank is connected to a grease trap. The intake receptacle receives waste fry oil directly from a fryer. The internal combustion engine is a diesel engine. The electrical generator provides electrical power to: a facility including a commercial business, a residential dwelling, a maritime vessel, a train, a storage facility, an industrial facility, a warehouse, a mobile dwelling, or a camp; a local electrical power distribution grid; and an electrical storage device. The electrical generator comprises a synchronous generator or inductive generator adapted to provide interconnection to a local electrical power distribution grid. The internal combustion engine provides power to the drive train of a vehicle comprising a hybrid diesel/electric vehicle. The excess thermal energy is used to heat domestic hot water or air in a building. The fuel heat exchanger is operated under reduced pressure to promote water removal at a temperature of less than 212 degrees F. The fuel heat exchanger is operated at a temperature and pressure such that long chain waxes within the fuel pass through a fine fuel filter disposed in a fuel line running from the fuel heat exchanger. The fuel heat exchanger provides direct thermal communication between an amount of flowing waste-recovered fuel and at least a portion of the fuel-warming system. The residence time of the amount of waste-recovered fuel flowing through the fuel heat exchanger is controlled such that water within the amount of fuel boils. The amount of waste-recovered fuel within the heat exchanger reaches a temperature of 212-275 degrees F. The secondary fuel tank is disposed between an intake tank or fuel heat exchanger and the internal combustion engine. The secondary source of energy comprises electricity, microwaves and/or solar radiation. The secondary fuel tank is further adapted to provide heated fuel to: the internal combustion engine for combustion; or a fluid circulation circuit disposed with the internal combustion engine. The fluid circulation circuit elevates the temperature of an engine component to promote combustion of the waste-recovered fuel. The fluid circulation circuit provides heat to the engine block of the internal combustion engine, to high-pressure fuel lines running to cylinders in the engine and/or to a fuel pump which provides fuel to the engine's cylinders. The solids processing unit utilizes thermal energy from engine combustion products. The organic solids are transformed by gasification or pyrolysis. (I) is sized to substantially match its fuel consumption rate to the rate of generation of fuel-laden waste by the source of fuel-laden waste over a selected period of time.
