Abstract
An on-site electrical power generation system utilizing environmentally hazardous waste oils as a combustible fuel. The disclosed invention utilizes the combustion of environmentally hazardous waste oils to drive a heat engine and electrical generator. In addition, the system is adapted to provide local space heating and hot water as a byproduct of the combustion process.
Claims25
A system related to mechanical power generation through the burning of environmentally hazardous waste oils, said system comprising:
- a) at least one combustion heater structured and arranged to produce combustion heat through the burning of such environmentally hazardous waste oils;
- b) at least one vaporizer structured and arranged to vaporize a working fluid using the combustion heat produced by said at least one combustion heater;
- c) at least one thermodynamic energy converter structured and arranged to convert heat extracted from combustion of the vaporized working fluid into at least one output of mechanical work;
- d) at least one condenser structured and arranged to condense vaporized working fluid exiting said at least one thermodynamic energy converter;
- and
- e) operably coupled with said at least one condenser, at least one fluid pump to pump condensed working fluid between said at least one condenser and said at least one vaporizer;
- f) wherein said at least one combustion heater comprises
- i) at least one air intake path, comprising at least one air blower, structured and arranged to deliver at least one combustion airflow to said at least one combustion heater,
- ii) at least one atomizer structured and arranged to produce an atomized mist of such environmentally hazardous waste oils within the at least one combustion airflow,
- iii) at least one ignition source to ignite the atomized mist of such environmentally hazardous waste oils within the at least one combustion airflow, and
- iv) at least one exhaust path to exhaust hot combustion gases from said at least one combustion heater;
- g) wherein said at least one air intake path comprises at least one first heat exchanger to preheat the at least one combustion airflow using the latent heat of vaporization extracted from the condensation of the working fluid within said at least one condenser;
- and
- h) wherein said at least one air intake path comprises at least one second heat exchanger to preheat the at least one combustion airflow using heat extracted from the hot combustion gases exhausted through said at least one exhaust path.

A system related to on-site burning of on-site-generated waste oils for the purpose of on-site electrical power generation, said system comprising:
- a) at least one holder structured and arranged to hold such on-site-generated waste oils;
- b) at least one combustion heater structured and arranged to produce combustion heat by burning such on-site-generated waste oils;
- c) at least one waste oil transfer component structured and arranged to transfer such on-site-generated waste oils from at least one holder to said at least one combustion heater;
- and
- d) operably coupled to said at least one combustion heater, at least one heat-energy converter structured and arranged to convert such combustion heat to electrical power;
- e) wherein said at least one heat energy converter comprises
- i) at least one Rankine-cycle external-combustion heat engine structured and arranged to convert such combustion heat to mechanical power, and
- ii) operationally coupled to said at least one Rankine-cycle external-combustion heat engine, at least one electrical generator adapted to the generate electrical power;
- f) wherein said at least one holder comprises at least one collector structured and arranged to assist in on-site collecting of such on-site-generated waste oils;
- g) wherein said at least one waste oil transfer component comprises at least one waste-oil pump to pump such on-site-generated waste oils from said at least one holder to said at least one combustion heater;
- h) wherein said at least one combustion heater comprises:
- i) at least one atomizer structured and arranged to atomize such on-site-generated waste oils prior to combustion;
- and
- ii) at least one igniter adapted to ignite such on-site-generated waste oils after such on-site-generated waste oils have passed through said at least one atomizer.
