Experimental Study on Electrostatic Spraying Technique Effects of Gasoline Combustion Characteristics

Abstract

The combustion characteristics of gasoline, set up a test-bed combustion technology based on electrostatic spray, the combustion chamber along the axial position of the gas temperature and the variation of the combustion chamber flue gas composition of the key position of the test. Experiment iron drum simulation of the combustion chamber of 50cm and 80cm in diameter and height, respectively, in the longitudinal uniform on one side of the barrel with a straight line 10cm away from play a number of hole; Santana 3000 fuel injection enables fuel atomization; needle electrode and the electrostatic generator gasoline to bring the static. When the injector spray out of petrol continued to burn so that the thermocouple and the exhaust gas analyzer probe is inserted into the through hole to the metal pail each height of the center, respectively, to test the barrel along the axial position of the gas temperature before and after to bring static variation of gas composition and key positions. Experimental results show that the electrostatic spray combustion technology can significantly improve the thermal efficiency of gasoline combustion and improve flue gas emissions, the use of electrostatic spray combustion technology, near the nozzle temperature increases can be achieved in about 18%ï¼› HC emissions decrease can reach more than 60%, decrease of CO emissions can be achieved in more than 58%, the increase of CO2 emissions can be achieved more than 52%, NOX emissions decrease can reach more than 45% percent, a new idea for energy saving.
