Methods and device for low contamination energy generation

摘要

A method for low-contamination generation of energy comprising: (a) forming a gas mixture by mixing a treated gaseous effluent stream and air; (b) introducing the gas mixture and fuel at a given gas to fuel ratio into at least one diesel engine (3); (c) burning the fuel in the diesel engine to generate energy and a flue gas stream comprising particulate matter (PM), and nitrogen oxides (NOx); (d) treating at least a portion of the flue gas stream with an aqueous stream in a cyclone unit (27) comprising a housing defined by a cylindrical peripheral wall (2) and provided with at least one inlet opening (10) for receiving flue gas and at least one inlet opening for receiving fluids thereinto and with at least one swirling means, whereby a treated gaseous effluent stream and an aqueous effluent stream are formed; (e) emitting a portion of the treated gaseous effluent stream to form an emitted portion; (f) using a portion of the treated gaseous effluent stream to form the gas mixture, and (g) repeating steps (a) through (f) multiple times.

1. A method for low-contamination generation of energy comprising:
(a) forming a gas mixture by mixing a treated gaseous effluent stream and air; (b) introducing said gas mixture and fuel at a given gas to fuel ratio into at least one diesel engine; (c) burning said fuel in said diesel engine to generate energy and a flue gas stream comprising particulate matter (PM), and nitrogen oxides (NOx); (d) treating at least a portion of said flue gas stream with an aqueous stream in a cyclone unit comprising a housing defined by a cylindrical peripheral wall and provided with at least one inlet opening for receiving flue gas and at least one inlet opening for receiving fluids thereinto and with at least one swirling means, and wherein said cyclone unit is characterized in that the velocity of said flue gas stream inside said cyclone unit is between 20 m/sec and 120 msec, whereby a treated gaseous effluent stream and an aqueous effluent stream are formed; (e) emitting a portion of said treated gaseous effluent stream to form an emitted portion; (f) using a portion of said treated gaseous effluent stream to form said gas mixture, and (g) repeating steps (a) through (f) multiple times; whereby said emitted portion has reduced PM, and reduced NOx content when compared with a reference gaseous effluent stream formed by standard burning of the same fuel in an identical engine to which air and fuel are provided in the same given gas to fuel ratio as above.
